 | Billing 

Did You Know?

The Code of Federal Regulations defines colorectal cancer screening tests as being any of the following procedures furnished to an individual for the purpose of early detection of colorectal cancer:

  • Screening fecal-occult blood tests.
  • Screening flexible sigmoidoscopies.
  • Screening colonoscopies, including anesthesia furnished in conjunction with the service.
  • Screening barium enemas.
  • Other tests or procedures established by a national coverage determination, and modifications to tests under this paragraph, with such frequency and payment limits as CMS determines appropriate, in consultation with appropriate organizations.

Why It Matters?

Effective January 1, 2023: If you code outpatient colonoscopy procedures, be aware of new Medicare guidelines where a positive stool-based colorectal cancer-screening test can, in some cases, constitute a screening colonoscopy.

The excerpt below is from the Code of Federal Regulations and can be seen in section K at this link: eCFR :: 42 CFR 410.37 -- Colorectal cancer screening tests: Conditions for and limitations on coverage.

“A complete colorectal cancer screening. Effective January 1, 2023, colorectal cancer screening tests include a follow-on screening colonoscopy after a Medicare covered non-invasive stool-based colorectal cancer screening test returns a positive result.”

Also refer to Coding Clinic for HCPCS 4th quarter 2022, page 17 for additional information.

What Can I Do?

Share this information with your outpatient coding professionals. For non-Medicare payers, it may be necessary to contact them directly for guidance.

March 2023 PAR PRO Tip: Facet Joint Interventions to Require Prior Authorization July 1, 2023
Published on Mar 15, 2023

MMP’s Protection Assessment Report (P.A.R.) combines current Medicare Fee-for-Service review targets (i.e., MAC, RAC, OIG) with hospital specific paid claims data made possible through a collaboration with RealTime Medicare Data (RTMD). Monthly, we spotlight review activities. This month, we bring you highlights from the MACs as they prepare for and provide education related to facet joint interventions being added to Prior Authorization for Certain Hospital Outpatient (OPD) Services CMS initiative.

Prior Authorization for Certain Hospital Outpatient Department Services

CMS implemented this initiative through the Calendar Year 2020 Outpatient Prospective Payment System/Ambulatory Surgical Center (OPPS/ASC) Final Rule (CMS-1717-FC). Effective for claims on or after July 1, 2023, CMS has added facet joint interventions to the list of services requiring prior authorization. This service category includes facet joint interventions, medial branch blocks, and facet joint nerve destruction. A list of the specific CPT codes is in Table 103 of the CY 2023 OPPS/ASC Final Rule (CMS-1772-FC). Following is current guidance available on MAC websites:

J15: CGS Administrators LLC 

 “CGS will accept prior authorization requests for these services beginning on June 18, 2023…Information specific to facet joints will be added as it becomes available.” 

JN: First Coast Service Options Inc.

On March 14th, First Coast added information regarding facet joint interventions to their Prior Authorization for certain hospital OPD services webpage ( At the same time, they published a separate article titled Be sure you are billing correctly for Prior authorization (PA) for face jont interventions ( 

JE/JF: Noridian Healthcare Solutions, LLC

“Introductory letters will be mailed during the month of May 2023, to providers currently billing for facet joint interventions in hospital OPDs.” 

J6/JK: National Government Services Inc.

“On 6/15/2023, National Government Services will begin accepting prior authorization requests for facet joint services.” 

JH/JL: Novitas Solutions Inc.

As of March 14th, information about facet joint interventions as part of the prior authorization initiative has not been added to the Novitas website. Novitas does have a very informative webpage dedicated to this program ( I encourage you to check this webpage often for updates. 

JJ/JM: Palmetto GBA, LLC

“On June 15, 2023, Palmetto GBA will begin accepting prior authorization requests for facet joint services (” 

Also, Palmetto GBA is hosting a webinar on April 13, 2023. During this webinar they will discuss the OPD process, the new CPT codes that are being added for Facet Joint Interventions and required documentation. If you are interested in attending this webinar, the webinar announcement includes a link to sign up ( 

J5/J8: Wisconsin Physicians Service Government Health Administrators

The topic for WPS’s monthly medical review errors webinar on March 21st is Facet Joint documentation. During this webinar, WPS will focus on the documentation requirements for facet joint interventions, to aid in avoiding future denials. 

Moving Forward

Visit your MACs website frequently to:

Identify when they will begin to accept prior authorization requests and for any updates or planned educational sessions, 

 Identify applicable Medicare Coverage Documents (Local Coverage Determinations (LCDs) and Local Billing and Coding Articles (LCAs)), and

Ensure key stakeholders are aware of the need for prior authorization effective July 1, 2023 (i.e., Outpatient Department Nurse Manager, Scheduling, Physicians performing these procedures) and educate them on applicable documentation requirements found in the LCDs and LCAs.

February 2023 PAR Physician Part B Pro Tip: Transthoracic Echocardiography
Published on Feb 22, 2023
 | Billing 
 | Coding 

MMP’s Protection Assessment Report (P.A.R.) combines current Medicare Fee-for-Service review targets (i.e., MAC, RAC, OIG) with hospital specific paid claims data made possible through a collaboration with RealTime Medicare Data (RTMD). Monthly, our newsletter spotlights current review activities.


February 22nd is National Heart Valve Disease (HVD) Awareness Day. One way to diagnose HVD is to perform an echocardiogram. You can read more about causes, risk factors, symptoms, and treatment of HVD  in a related article in this week’s newsletter. This article highlights one MAC’s Targeted Probe and Educate (TPE) review results for Transthoracic Echocardiography (CPT® code 93306).  


Palmetto GBA Jurisdiction J Part B TPE Review Results for Transthoracic Echocardiography July through September 2022

Palmetto GBA recently published their review results for CPT® code 93306: Echocardiography, Transthoracic, Real-Time with Image Documentation, for July through September 2022 claims. Jurisdiction J includes Alabama, Georgia, and Tennessee.


Review Results by the Numbers

  • Thirty-seven providers received additional documentation requests (ADRs) for claims for this review.
  • Palmetto GBA reviewed 1,480 claims.
  • The state specific claim denial rate was 35% in Tennessee, 46% in Alabama and 50% in Georgia.
  • Overall, 45% of the claims were denied.
  • The total dollar denied amount was $101,664.11.
  • Twenty-five providers were found to be “non-compliant” and will progress to a second TPE review of records.


    National Volume and Payment for CPT® 93306 July – September 2022 Claims

    In Palmetto GBA’s article Medicare Coverage of Echocardiography, they “identified CPT 93306 as an area of vulnerability” and noted “this code is a major risk.” As this is a TPE review target, is seems Palmetto GBA continues to identify CPT® 93306 as “an area of vulnerability” and “major risk.”


    Since the RTMD database now covers all 50 states and D.C. and inpatient discharges, outpatient hospital services and CMS 1500 Professional Services, I wanted to quantify this “major risk” at the national level.


    RTMD July-September 2022 Part B Professional Claims by Site of Service

    • Non-Hospital: 710,467 claims volume and $107,785,891 payment
    • 21-Inpatient Hospital: 569,770 claims volume and $30,110,417 payment
    • 22-Outpatient Hospital: 556,523 claims volume and $29,110,491 payment
    • 19-Off Campus-Outpatient Hospital: claims 85,517 volume and $4,624,688 payment
    • 23-Emergency Room Hospital: 12,983 claims volume and $674,203 payment


    The Total Volume was 1,935,260 and the Total Payment was $172,305,690. For this three-month time, a 45% claims denial rate equates to 870,867 non-paid claims with a loss in revenue of just over $77.5 million.


    Reasons for Claim Denial

  • 26% of the denials were due to Palmetto GBA not receiving the documentation requested or the documentation was incomplete, and they were unable to make a reasonable and necessary determination.
  • 24% of denials were due to the documentation that was submitted not supporting medical necessity of the services billed based on Palmetto GBA’s applicable Local Coverage Determination (LCD L37379).
  • 19% of the denials were due to documentation containing an incorrect, incomplete, or illegible patient identification or date of service.
  • 18% of the denials were due to a claim billed in error by the Provider.
  • Finally, 11% of the denials were due to documentation not being signed by the rendering Provider.


    Specific to documentation not supporting medical necessity, Palmetto GBA noted in the article mentioned above, that “Echocardiography performed for screening purposes is not covered. Screening includes testing performed on patients who present with risk factors (including the risk factor such as having a positive family history, e.g., familial history of Marfan’s disease). Screening service for high-risk patients is considered good medical practice but is not covered by Medicare. When a screening test is performed, use the appropriate screening ICD-10 code to indicate the test is being done for screening purposes. When the result of the test is abnormal, subsequent diagnostic services may be billed with the test-result diagnosis; however, the initial screening test must be listed as screening, even though the result of the screening test may be a covered condition. Symptoms or an existing condition must be present in the medical record to meet medical necessity.”


    Moving Forward

    For Providers in Palmetto GBA’s Jurisdiction J or M, Take the time to read LCD L37379 and related Local Coverage Article (LCA) A56625 to identify covered indications and diagnoses for this procedure. Palmetto GBA has also made available an on-demand webinar Medicare Coverage of Echocardiography CPT® Code 93306, noting it should be of interest to the Part B Providers staff, managers, supervisors, medical record departments or third parties that respond on behalf to medical records requests from Palmetto GBA or any other CMS review contractor.


    For Providers in other MAC jurisdictions, search the Medicare Coverage Database to identify any applicable LCDs or LCA in place for CPT® 93306.

National Medicare Claims Review Contractor Year One Review Results
Published on Feb 15, 2023
 | Billing 
 | Coding 

We are fast approaching the ten-year anniversary of the Two-Midnight Rule that went into effect on October 1, 2013. Following the start date of this rule, CMS provided sub-regulatory guidance. Specific to claims reviews, CMS directed Medicare review contractors to apply the Two-Midnight presumption that “directs medical reviewers to select Part A claims for review under a presumption that the occurrence of 2 midnights after formal inpatient hospital admission pursuant to a physician order indicates an appropriate inpatient status for a reasonable and necessary Part A claim.”

Initially, Medicare Administrative Review Contractors (MACs) were tasked with auditing short stay claims. Next, this task was turned over to the two Beneficiary and Family Centered Care Quality Improvement Organizations (BFCC-QIOs) KEPRO and Livanta. In 2019, reviews were halted as CMS began the process of selecting one contractor to perform Short Stay Reviews (SSRs) and Higher Weighted DRG (HWDRG) reviews nationally.

In April 2021, Livanta announced they had been awarded the contract to be the National Medicare Claim Review Contractor. Livanta notes on their website that “claim review services represent an important activity of advancing Medicare’s triple aim of better health, better care, and lower costs.”

In October 2021, Livanta began requesting records monthly and they have recently posted their First Year Review Findings for SSRs and HWDRG reviews.

First Year Review Findings for Short Stay Reviews

Livanta notes in this report that SSRs focus on appropriate application of the Two-Midnight Rule, they are not incentivized to find errors, providers may provide supplementation documentation for initially denied claims, and a hospital may request education sessions at any point in the review process.

Livanta developed a review strategy, approved by CMS, to score each eligible paid claim to account for the influences of volume, cost, and clinical risk of improper payment. This score also scores a claim by length of stay (LOS) with a 0-day LOS scoring higher than a 1-day LOS.


Year 1 Report Highlights

  • Livanta reviewed 18,672 short stay claims,
  • 2,663 (14%) reviews were denied,
  • The 0-Day LOS error rate was eighteen percent,
  • The 1-Day LOS error rate was thirteen percent,
  • The highest volume of claims denied were circulatory system claims, and
  • The principal diagnosis with the highest number of denials was I480 (Paroxysmal atrial fibrillation).

    Higher Weighted DRG Reviews

    A HWDRG review occurs when a claim is resubmitted by a hospital with a higher weighted DRG as a correction to an original claim. The focus of this type of review is “on medical necessity of the inpatient admission and DRG validation.” Further, “this review activity helps ensure that the patient’s diagnostic, procedural, and discharge information is coded and reported properly on the hospital’s claim and matches documentation in the record.” Similar to SSRs, each claim is scored to account for the influences of volume, cost, and clinical risk.

    Year 1 Report Highlights

  • Livanta completed 54,251 reviews.
  • A Livanta physician identified 4,804 clinical coding errors due to lack of evidence to support the diagnosis code.
  • >There were 6,480 technical coding errors that involved inappropriate application of ICD-10-CM/PCS coding guidelines.

Top Three Reasons for a Denial

  1. The principal diagnosis was not supported by the medical record and coding guidelines.
  2. Submission of a major complication or comorbidity (MCC) or CC not supported by documentation in the medical record. Common diagnoses cited in the report were sepsis, encephalopathy, and malnutrition.
  3. Inappropriate query submissions and unsupported responses.

Moving Forward

Share this information with your Coding and Clinical Documentation Integrity professionals. I also encourage you to review information available to Providers on Livanta’s website and sign up for their monthly newsletter, The Livanta Claims Review Advisor.

The COVID-19 PHE is Coming to an End
Published on Feb 07, 2023

In an August 18, 2022 special edition of MLN connects, CMS sounded the call for providers to begin to prepare hospitals for operations after the COVID-19 Public Health Emergency (PHE) comes to an end.

Some five months later, On January 30, 2023, the Biden administration communicated their intent to end the COVID-19 national emergency and public health emergency (PHE) on May 11, 2023, noting that “This wind-down would align with the Administration’s previous commitments to give at least 60 days’ notice prior to termination of the PHE.”

CMS was quick to follow-up on this announcement and on February 1, 2023, they posted an update to the coronavirus waivers & flexibilities CMS webpage:   

  • “Update: On Thursday, December 29, 2022, President Biden signed into law H.R. 2716, the Consolidated Appropriations Act (CAA) for Fiscal Year 2023. This legislation provides more than $1.7 trillion to fund various aspects of the federal government, including an extension of the major telehealth waivers and the Acute Hospital Care at Home (AHCaH) individual waiver that were initiated during the federal public health emergency (PHE).
  • Additionally, on January 30, 2023, the Biden Administration announced its intent to end the national emergency and public health emergency declarations on May 11, 2023, related to the COVID-19 pandemic.
  • CMS is committed to updating supporting resources and providing updates as soon as possible. Please continue to use the provider-specific fact sheets for information about COVID-19 Public Health Emergency (PHE) waivers and flexibilities.” Note, all provider-specific fact sheets were recently updated on February 1, 2023 and include information about the status of waivers when the PHE ends, for example:  


Fact Sheet: Physicians and Other Clinicians: CMS Flexibilities to Fight COVID-19

  • Medicare Telehealth: The Consolidated Appropriations Act of 2023 provides for an extension for some of the flexibilities through December 31, 2024. However, when the PHE ends Clinicians must once again have an established relationship with the patient prior to providing remote patient monitoring (RPM).
  • Reducing Administrative Burden: “Stark Law” waivers: When the PHE ends, all Stark Law waivers will terminate, and physicians and entities must immediately comply with all provisions of the Stark Law.
  • National Coverage Determinations (NCDs) for Percutaneous Left Atrial Appendage Closure, Transcatheter Aortic Valve Replacement, Transcatheter Mitral Valve Replacement and Ventricular Assist Devices: CMS has not enforced the procedural volume requirements contained in these four NCDs for facilities and providers that, prior to the public health emergency for COVID-19, met the volume requirements. This enforcement discretion ensures that beneficiaries continue to have access to the services that are covered under these NCDs. This waiver will end at the conclusion of the PHE. 


Fact Sheet: Hospitals and CAHs (including Swing Beds, DPUs), ASCs and CMHCs: CMS Flexibilities to Fight COVID-19

  • Enhanced Medicare Payments for New COVID-19 Treatments: Hospital Inpatient Stays: Immediately following the end of the PHE, effective for discharges occurring on or after November 2, 2020, and through the end of the FY in which the COVID-19 PHE ends, the Medicare program has provided an enhanced payment for eligible inpatient cases that involve use of certain new products authorized or approved to treat COVID-19 (86 FR 45162). The enhanced payment is equal to the lesser of 1) 65% of the operating outlier threshold for the claim; or 2) 65% of the costs of the case beyond the operating Medicare payment (including the 20% add-on payment under section 3710 of the CARES Act) for eligible cases.
  • Separate Medicare Payment for New COVID-19 Treatments: Hospital Outpatient Departments: CMS has excluded FDA-authorized or approved drugs and biologicals (including blood products) authorized or approved to treat COVID-19 (and for which the FDA authorization or approval does not limit use to the inpatient setting) from being packaged into the Comprehensive Ambulatory Payment Classification (C-APC) payment when these treatments are billed on the same claim as a primary C-APC service. Instead, Medicare has been paying for these drugs and biologicals separately for the duration of the PHE. After the PHE, payment for these treatments will be packaged into the payment for a C-APC when these services are billed on the same outpatient claim.
  • Utilization Review: CMS has been waiving the entire Utilization Review Conditions of Participation (CoP) at §482.30 as “removing these administrative requirements allows hospitals to focus more resources on providing direct patient care.” This waiver will end at the conclusion of the PHE.


I have provided only a select few examples of what will happen when the PHE ends and encourage you to check for updates to the provider-specific fact sheets often as you develop a plan for your hospital beyond the end of the COVID-19 PHE.

FY 2022 HHS Agency Financial Report
Published on Jan 30, 2023
 | Coding 
 | Billing 

Payment Integrity: Medicare FFS Hospital Outpatient

The FY 2022 HHS Agency Financial Report ( was published in late 2022.  Section 3 of this document includes the Payment Integrity Report where HHS indicates “the actual overpayments identified by the Comprehensive Error Rate Testing program during the FY 2022 report period were $24,004,089.28. The MACs recovered the identified overpayments via standard payment recovery methods. As of the report publication date, MACs reported collecting $15,552,853.67 or 64.79 percent of the actual overpayment dollars.”


The improper payment estimate for hospital outpatient claims increased from 4.57 percent in RY 2021 to 5.43 percent in RY 2022. However, this increase was not statistically significant. The primary reason cited for hospital outpatient errors was “missing documentation to support the order, or the intent to order for certain services.   


Mitigation Strategies and Corrective Actions

HHS addresses improper payments through mitigation strategies and corrective actions believing that “targeted actions will prevent and reduce improper payments in these areas.” Strategies and corrective actions in the hospital outpatient setting cited in this report includes:  


Internal Policy Change: In 2020, HHS implemented the Prior Authorization for Certain Hospital Outpatient Department (OPD) Services process. This initiative was once again expanded in the CY 2023 OPPS Final Rule to include Facet Joint interventions effective July 1, 2023.


Internal Process: Medical Review Strategies

Medical review strategies are developed “using improper payment data to target the areas of highest risk and exposure. HHS requires its Medicare review contractors to identify and prevent improper payments due to documentation errors in certain error-prone claim types,” including hospital outpatient claims.


Audits: Targeted Probe & Educate (TPE)

Medicare Administrative Contractors (MACs) perform the TPE process. In 2022, MACs continued to offer extensions as needed due to the continued impacts of COVID-19. Approximately 3,280 hospital outpatient providers were reviewed by the MACs in 2022.


Audits: Supplemental Medical Review Contractor (SMRC)

The SMRC conducts reviews on a post-payment basis at the direction of CMS. When the SMRC completes a review, the results are shared with the MACs for claim adjustments. Providers receive detailed review result letters and MAC demand letters for overpayment recovery. Letters include educational information regarding what was incorrect in the original billing of the claim. In 2022, the SMRC performed post-payment medical reviews for 26,777 hospital outpatient claims.


Audits: Recovery Audit Contractor (RAC) Reviews

In 2022, the largest share of Medicare FFS RAC collections (37.4 percent) were from hospital outpatient overpayments.


Moving Forward

  • Prepare for the July 1, 2023 addition of Facet Joint interventions to the Prior Authorization for Certain OPD Services process.
  • Identify active TPE, SMRC and RAC review targets to assess your compliance with related documentation, coding, and billing requirements.
  • Respond to additional documentation requests in a timely manner.

COVID-19 Updates

January 11, 2023: Public Health Emergency Declaration Renewed

As expected, on January 11, 2023, the Public Health Emergency (PHE) renewed for the twelfth time. PHE declarations last for the duration of the emergency of 90 days and may be extended by the Secretary. Ninety days from January 11th will be April 11, 2023. Specific to the COVID-19 PHE, HHS has indicated that they will provide a 60-day notice prior to termination of the COVID-19 PHE (March 12, 2023). It is unclear if the PHE will last beyond April 2023.

Other Updates

New ICD-10 Diagnosis and Procedure Codes Effective April 1, 2023

As a reminder, there are 34 new procedure codes and 42 new diagnosis codes that will be effective April 1, 2023. In their announcement listing the new diagnosis codes they note that “In an effort to better enable the collection of health-related social needs (HRSNs), defined as individual-level, adverse social conditions that negatively impact a person’s health or healthcare, are significant risk factors associated with worse health outcomes as well as increased healthcare utilization, the Centers for Disease Control and Prevention’s (CDC) National Center for Health Statistics (NCHS) is implementing 42 new diagnosis codes into the International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM), for reporting effective April 1, 2023.”

Coverage Updates

Percutaneous Transluminal Angioplasty (PTA) of the Carotid Artery Concurrent with Stenting

In June 2022, the Multispecialty Carotid Alliance (MSCA) submitted a formal request for reconsideration of the National Coverage Determination (NCD) 20.7: PTA that provides coverage for carotid artery stenting (CAS). In their letter they indicated evidence supports the following changes to the NCD:

  1. Expand patient selection criteria to reflect the established data from research:
    1. Revise the patient selection criteria for PTA and CAS with embolic protection to cover the following:
      1. Patients who have asymptomatic carotid artery stenosis ≥ 70%, and
      2. Patients who have symptomatic carotid artery stenosis ≥ 50%.
    2. Eliminate the requirement that patients be at high risk for CEA:
  2. Eliminate the minimum standards for facility requirements; and
  3. Leave coverage for any CAS procedures not described by the NCD to the discretion of the local Medicare Administrative Contractors (MACs).

On January 12, 2023, CMS accepted the formal request, initiated a National Coverage Analysis (link) and are accepting public comments from January 12, 2023 through February 11, 2023. The expected due date for a proposed decision memo is July 12, 2023.
