Collaboration is a process of working together to complete a task or achieve a goal.

For the Clinical Documentation Integrity Specialist, the goal of ensuring a patient’s story can be accurately reflected in codes (ICD-10-CM/PCS, HCPCS, CPT), requires collaborating with a team that can include physicians, nursing, dietitians, physical therapists, case managers, social workers, and coding professionals.

For the Case Manager, to ensure a patient’s story supports medical necessity of the services being provided and the patient has an appropriate discharge plan in place, this process, in addition to the above professions, requires open communication with the patient and his or her “people.”

Physicians must also collaborate with a team. In fact, CMS recently updated their MLN Fact Sheet: Collaborative Patient Care is a Provider Partnership (link). This Fact Sheet opens with the following guidance:

“As a physician, supplier, or other health care provider, you may need to collaborate with other providers when providing care to your Medicare patients. For example, you may:

• Write orders
• Make referrals
• Request health care services or items for your patient

It’s important to understand Medicare coverage criteria and documentation requirements that apply for those services or items. This helps to ensure:

• Quality care for your patient
• Accurate and timely processing and payment of:
• Your claims, and
• The claims of other providers or suppliers who provide services or items for your patient

Note: This fact sheet is limited to information and documentation you need to support medical necessity when you partner with other providers. Other coverage and payment rules may also apply.”

Medicare Coverage Criteria and Documentation Requirements

Title XVIII of the Social Security Act, Section 1862 (a)(1)(A) states “No payment may be made under Part A or Part B for expenses incurred for items or services which…are not reasonable and necessary for the diagnosis or treatment of illness or injury or to improve the functioning of a malformed body member…”

At the national level, CMS publishes National Coverage Determinations (NCDs) and at the local level, Medicare Administrative Contractors (MACs) publish Local Coverage Determinations (LCDs) and Local Billing and Coding Articles (LCAs). Coverage documents provide guidance for when a service is covered or not covered, and include indications for coverage, limitations of coverage, documentation requirements and billing and coding guidance.

It is important to become familiar with where to find these documents (Medicare Coverage Database (link) and identify any NCDs, LCDs, and/or LCAs that apply to services that you provide. For example, at the national level, there is a NCD for Implantable Automatic Defibrillators (20.4) (link). In addition to the NCD, several MACs have published a related Billing and Coding article.

Ensuring the Story is Correct

Understanding Medicare coverage criteria and documentation requirements is important. So much so, CMS utilizes Contractors (i.e., Recovery Auditors, Supplemental Medical Review Contractor, and MACs) to audit claims.

CMS notes in the MLN Fact Sheet, “Medicare audits frequently show that provider-submitted documentation doesn’t provide enough information to establish medical necessity. To ensure proper claims processing and payment, you must follow documentation requirements and meet Medicare coverage criteria.”

They also underscore the importance of documenting everything needed to meet Medicare payment requirements when collaborating with other Providers. For example, let us once again focus on implantable automatic defibrillators and the Shared Decision Making (SDM) encounter requirement. The SDM encounter is:

• A requirement for all patients receiving a defibrillator for primary prevention,
• Must occur between the patient and a Physician or Non-Physician Practitioner (i.e., Physician Assistant, Nurse Practitioner, or Clinical Nurse Specialist),
• An Evidenced-Based Decision Tool must be used to ensure topics like patient health goals and preferences are discussed,
• The encounter must occur prior to the initial implantation, and
• The encounter may occur at a separate visit.

Given the timing of when the SDM encounter should occur, it is likely that this would be done in the Physician’s office. Therefore, the physician would need to include in documentation provided to the hospital that an SDM encounter had occurred and what tool had been used.

CMS advises that a providers documentation needs to be thorough and accurate to support the medical necessity of services provided and should:

• Provide a thorough picture of what happened during the patient’s visit, and
• Tell why services or items you ordered or gave are medically necessary.

I opened this article by noting that collaboration is a process of working together to complete a task or achieve a goal. I end this article by noting that a successful collaboration requires the physician to tell each patient’s story in a way that supports the medical necessity of services provided and allows for coding professionals to translate the story into code for accurate billing and payment of the claim.

Did You Know?

45 is the new 50 for colorectal cancer screening.

Why It Matters?

The U.S. Preventive Services Task Force’s indicated in their May 18, 2021 Final Recommendation statement for colorectal cancer screening that (link):

• It is estimated that 10.5% of new colorectal cancer cases occur in persons younger than 50 years,
• Incidence of colorectal cancer (specifically adenocarcinoma) in adults aged 40 to 49 years has increased by almost 15% from 2000-2002 to 2014-2016,
• In 2016, 25.6% of eligible adults in the US had never been screened for colorectal cancer, and
• In 2018, 31.2% were not up to date with screening.

What Can You Do?

There are five types of tests used to screen for colorectal cancer:

• Fecal occult blood test,
• Sigmoidoscopy,
• Colonoscopy,
• Virtual colonoscopy, and
• DNA stool test.

As a healthcare provider, be aware of Medicare’s colorectal screening coverage. According to the MLN Educational Tool Medicare Preventive Services (link), Medicare covers:

• Colorectal cancer screening using MT-sDNA and blood-based biomarker tests for patients with Medicare Part B who meet these criteria:
  • Aged 50-85 years,
  • Asymptomatic, and
  • At average risk of colorectal cancer risk.
• Screening colonoscopies, fecal occult blood tests (FOBTs), flexible sigmoidoscopies, and barium enemas for patients with Medicare Part B who meet at least one criterion:
• Aged 50 or older at normal colorectal cancer risk (there’s no minimum age requirement for screening colonoscopies), or
• Are at high colorectal cancer risk.

Also, Medicare has published a National Coverage Determination (NCD 210.3) Colorectal Cancer Screening Tests (link). The most current iteration of this NCD became effective on January 19, 2021, to include blood-based biomarker testing as an appropriate colorectal cancer screening test based on specific criteria.

My first screening colonoscopy was performed when I was 45 years old. During the procedure a pre-cancerous polyp was removed. As a healthcare consumer, I encourage everyone to talk with your doctor to discuss your risk for colorectal cancer and the need for screening tests.

Question

Our gastroenterologists rarely state if a patient’s personal history of colon polyps is adenomatous in nature or hyperplastic, or both. Typically, the documentation only reflects that the patient has a “history of colon polyps”. If the physician specifies the patient’s previous colon polyps as being hyperplastic, what ICD-10-CM diagnosis code should be assigned?

Answer

For a personal history of hyperplastic colon polyps, assign ICD-10-CM diagnosis code Z87.19 (personal history of other diseases of the digestive system).

Did You Know?

The advice from Coding Clinic, First Quarter 2021, page 12 advises that medications prescribed on a “PRN” or “as needed” basis are not considered to be long term drug therapy. This means that Z79, Long Term Drug Therapy would not be assigned for these medications.

Why It Matters?

Coding long term medication use for a drug that is given only on an “as needed” basis would be contradictory to the Z79 code description as it implies continuous use of a drug for an extended period of time.

What Can I Do?

Review Coding Clinic, 1ST Quarter 2021, page 12. Read the medication list, determine the medications to be coded and then look to see how they are prescribed.

Did You Know?

February is American Heart Month. Per NCD 210.11 (link), cardiovascular disease (CVD):

• Is the leading cause of mortality in the United States,
• Is comprised of hypertension, coronary artery disease (i.e., myocardial infarction and angina pectoris), heart failure and stroke, and
• Is the leading cause of hospitalizations.

Risk Factors for CVD includes:

• Being overweight,
• Obesity,
• Physical inactivity,
• Diabetes,
• Cigarette smoking,
• High Blood Pressure (HTN),
• High blood cholesterol,
• Family history of myocardial infarction, and
• Older age

Why this Matters?

Annually, the CERT publishes a supplemental improper payment data report. Table D4, in the supplemental report (link), highlights the top 20 service types with the highest improper payments for Part A IPPS Hospitals. This table also details the percentage of error by each of the CERT’s major error categories:

• No documentation,
• Insufficient documentation,
• Medical necessity.
• Incorrect coding, and
• Other.

In the 2021 supplemental data, nine of the top twenty service types with highest improper payments were DRGs in the major diagnostic category (MDC) 5 Diseases and Disorders of the Circulatory System. Insufficient documentation and medical necessity were the two most common type of errors cited for this group of service types.

The projected improper payment for the circulatory system service types is $714,632,739 representing 36% of the total projected improper payments for the top twenty service types.

What Can You Do?

Be proactive for your patients by becoming familiar with the cardiovascular disease screening tests and intensive behavioral therapy for cardiovascular disease covered by Medicare and additional resources published in the February 10, 2022 edition of MLN Connects (link):

• Preventive Services webpage (link)
• Achieving Health Equity web-based training (link)
• CMS Office of Minority Health, Health Observances webpage (link)
• Million Hearts® (link): HHS initiative to prevent a million heart attacks and strokes
• Cardiovascular disease screenings coverage (link) & behavioral therapy (link): information for your patients

Become familiar with coverage determinations related to the top services. For example:

• For DRGs 226 and 227 (Cardiac Defibrillator Implant without cardiac catheterization with MCC and without MCC respectively), there is a National Coverage Determination (NCD 20.4) and Medicare Administrative Contractor (MAC) specific Local Coding and Billing Articles.
• Transcatheter Aortic Valve Replacement (TAVR) and TEER (Transcatheter Edge-to-Edge Repair) procedures fall within DRGs 266 and 267. Both procedures have a related NCD (TAVR NCD 20.32 and TEER NCD 20.33).
• Percutaneous Left Atrial Appendage Closure (LAAC) procedures fall within DRGs 273 and 274 and has a related NCD (20.34).
• For DRG 313 (Chest Pain), Palmetto GBA the Jurisdiction J and M MAC, has a Local Coverage Determination (LCD L34551) titled, One Day Stays for Chest Pain.

Finally, respond to requests for documentation in a timely manner, sending adequate documentation to support the medical necessity of the services provided.

Question

We have a patient that was admitted through the ED with significant shortness of breath and acute respiratory distress, with the CT scan of the lungs showing bilateral infiltrates. The patient tested negative for COVID-19 on admission. The patient was treated for pneumonia and acute hypoxic respiratory failure. However, four days into the stay, a second COVID-19 test was performed and the results were positive. What POA do we assign in this case?

Answer

Due to the many nuances, complexities, and incubation period of COVID-19, we cannot assume that the infection was POA or occurred after admission, based on the date of the test. Any issues relating signs and symptoms, the timing of test results, or findings, should be referred to the provider for the most appropriate assignment of the POA.

Did You Know?

In October 2021, CMS published Change Request (CR) 12471 (link). There were two stated purposes for this CR noted in the Summary of Changes:

• • Implement system changes needed to update the Shared System Maintainer (SSM) interface with the Java MCE to accept new MCE Edit 20-Unspecific Code Edit, and
• • Provide a mechanism to systematically bypass the new edit when a specific billing note is present in the claim remarks field to indicate the primary reason why laterality could not be determined

The effective date for this CR is April 1, 2022.

Why this Matters?

In ICD-10-CM there are unspecified codes for when documentation in the record does not provide detail needed to report a more specific code. “However, in the inpatient setting, there should generally be very limited and rare circumstances for which the laterality (right, left, bilateral) of a condition is unable to be documented and reported.”

Effective for claims with dates of service on or after April 1, 2022, new Code Edit 20- will be triggered when an unspecified diagnosis code currently designated as either a Complication or Comorbidity (CC) or Major Complication or Comorbidity (MCC), that includes other codes in that code subcategory that further specify the anatomic site, is entered.

You will find the complete list of 3,432 ICD-10-CM unspecified codes subject to this edit in table 6P.3a associated with the FY 2022 IPPS/LTCH Final Rule (link).

This edit is meant to signal providers that there is a more specific laterality code available to report. It will be the providers responsibility to determine if documentation in the medical record support’s a more specific code. “If, upon review, additional information to identify the laterality from the available medical record documentation by any other clinical provider is unable to be obtained or there is documentation in the record that the physician is clinically unable to determine the laterality because of the nature of the disease/condition, then the provider must enter that information in the remarks section.

Mechanism to Bypass new MCE Edit 20-

The provider may enter a remark:

• • Either “UNABLE TO DET LAT 1” to indicate that they are unable to obtain additional information to specify laterality, or
• • “UNABLE TO DET LAT 2” to indicate the physician is clinically unable to determine laterality

However, “if there is no language entered into the remarks section as to the availability of additional information to specific laterality and the provider submits the claim for processing, the claim would be returned to the provider.”

“0 or 1 day” Length of Stay Claims

After reading this CR, my first thought was, how often are one of these codes being included on a claim. To find the answer, I turned to our sister company, RealTime Medicare Data (RTMD). Following are the numbers for Medicare Fee-for-Service paid claims data with dates of service from October 1, 2020, through August 31, 2021, available in RTMD’s footprint:

• • 57,951 claims included one of the unspecified codes in Table 6P.3a of the FY 2022 IPPS/LTCH Final Rule,
• • The paid claims total for this set of claims was $1,010,178,584.54, and
• • The top five states by claims volume included:
• o California: 5,926 claims - $135,738,052.81
• o Texas: 5,872 claims - $104,453,156.02
• o New York: 3,290 claims - $70,001,125.23
• o Pennsylvania: 3,192 claims - $48,281,839.67
• o Illinois: 2,750 claims - $41,821,442.35

What Can You Do?

This is not a large volume of claims in the world of Medicare Fee-for-Service Inpatient paid claims. However, just over $1 billion in paid claims is a significant amount of money. With a little over a month to prepare, you should make sure that CR 12471 and related MLN Matters article MM12471(link) are shared with key stakeholders at your facility (i.e., Billing, Coding, Clinical Documentation Integrity Specialists). You should also work with your IT department to anticipate the potential volume of claims that will be impacted by the new Code Edit 20-.

A related article in this week’s newsletter (link), provides detail from the 2021 Comprehensive Error Rate Testing (CERT) program annual report and annual supplement data to the report. This article provides key facts about the CERT.

About the CERT

• The objective of the CERT program is to monitor and report the accuracy of claims payment in the Medicare Fee-for-Service program.
• CMS uses the CERT error rate to evaluate the performance of the Medicare Administrative Contractors (MACs).
• There are two CERT contractors:
• The CERT Review Contractor (CERT RC), and
• CERT Statistical Contractor (CERT SC).
• The CERT claim selection includes a stratified random sample of approximately 50,000 claims that are chosen by claim type (Part A, Part B and Durable Medical Equipment, Prosthetics, Orthotics, and Supplies (DMEPOS), and includes paid and denied claims by the MAC.
• The CERT process is a federally mandated program and not responding to documentation requests will result in a denial of all services billed on the claim.
• CERT request letters are mailed to the correspondence address listed in the Provider Enrollment, Change and Ownership System (PECOS).
• You can submit requested documentation to the CERT via postal mail, fax, Electronic Submissions of Medical Documentation (esMD), via CD or via email attachment(s).
• For short (less than 24 – 48 hours stay) inpatient hospital stay, a discharge summary is not required when a beneficiary is seen for minor problems or interventions, as defined by the medical staff. In this instance, a final progress note may be substituted for the discharge summary.
• The billing provider is responsible for obtaining medical records from the third-party to substantiate the claim that was billed.
• The CERT makes every effort to obtain the request documentation. Providers have 45 days to respond to the first letter requesting documentation. When the CERT does not receive the requested documentation by the 75th day, a claim is counted as a non-response error and is subject to overpayment recovery by the MAC.
• Claims reviews by the CERT includes program checks for compliance with Medicare statutes and regulations, billing instructions, National Coverage Determinations (NDCs), Local Coverage Determinations (LCDs), Local Coverage Articles (LCAs), and provision in the CMS instructional manuals.
• Denied claims as well as overpayments and underpayments are all considered to be an improper payment by the CERT program.
• Improper payments are attributed to one of five major error categories (no documentation, insufficient documentation, medical necessity, incorrect coding, or other).
• The improper payment rate is not a “fraud rate,” but a measurement of payments that did not meet Medicare requirements.
• Providers that wish to appeal a CERT contractor’s determination can follow the normal redetermination process to appeal all CERT denials.
• The CERT A/B MAC Outreach & Education Task Force has a goal to ensure consistent communication and education to reduce the Medicare Part A and Part B error rates. The Task Force webpage (link) includes education resources for providers.
