The Calendar Year (CY) 2021 Outpatient Prospective Payment System (OPPS) and Ambulatory Surgical Center (ASC) Payment System Final Rule (CMS-1736-FC) was released on December 2, 2020. This article focuses on changes to the Medicare Inpatient Only Procedure (IPO) List including medical reviews of procedures being removed from the list and additions to the Hospital Outpatient Prior Authorization Program that went into effect July 1, 2020.

Inpatient Only Procedure List

Currently, there are approximately 1,740 services on the IPO List. In the proposed rule, CMS proposed the following changes for CY 2021: 

  • Eliminate the IPO list over a three-year transitional period with the list completely phased out by CY 2024, and
  • Begin with the removal of nearly 300 musculoskeletal-related services.

They also requested comments on “whether three years is an appropriate time frame for transitioning to eliminate the IPO list; other services that are candidates for removal from the IPO list for CY 2021; and the sequence in which to remove additional clinical families and/or specific services from the IPO list in future rulemaking.”

Not surprisingly, CMS has finalized their proposal to phase out the IPO list by CY 2024. For CY 2021, 298 services are being removed from the IPO list and can be found in Table 48 of the final rule. This list includes:

  • 266 musculoskeletal related services,
  • 16 anesthesia codes related to the musculoskeletal procedures being removed, and
  • 16 additional procedures that were recommended for removal by the Hospital Outpatient Panel (HOP).

“All 298 services that are being removed from the IPO list beginning in CY 2021 are assigned status indicator “J1” and will receive payment through C-APCs, except for 34 services that are assigned status indicator “N”, which indicates that payment for the service is packaged into payment for other services and there is no separate APC payment, and two services assigned status indicator “Q1) which indicates conditionally packaged payment. CPT code 44314 (Revision of ileostomy; complicated (reconstruction in-depth) (separate procedure)), is the only code to be removed from the IPO list that is assigned status indicator “T”, indicating that it is a separately paid procedure. The vast majority of the procedures being removed from the IPO list for CY 2021 are assigned to C-APCs or packaged into payment for other services, which will result in beneficiaries paying one copayment amount.”

“Commenters urged CMS to develop national guidelines outlining beneficiaries who are appropriate candidates for the inpatient vs outpatient setting, particularly for services that generally have a short length of stay (i.e. do not meet 2-midnight benchmark).”

In response, CMS again stated that this decision is a complex medical judgment and should be based on a “beneficiary’s individual clinical needs.” However, they did note that they “agree with the commenters that, in the near term, in light of the elimination of the IPO list over a three-year period, physicians and providers could benefit from having access to general considerations for physicians regarding the types of services that may continue to be more appropriately performed in the inpatient setting for Medicare beneficiaries. Therefore, in the future, we plan to provide information on appropriate site of service selection to support physicians’ decision-making. We note that these considerations will be for informational or educational purposes only and will not supersede physicians’ medical judgment about whether a procedure should be performed in the inpatient or outpatient hospital setting.”

‍Medical Review of Certain Inpatient Hospital Admissions under Medicare Part A for CY 2021 and Subsequent Years (2-Midnight Rule)

The Two-Midnight Rule, as finalized in the FY 2014 IPPS Final Rule, clarified when an inpatient admission is to be considered reasonable and necessary for purposes of Medicare Part A payment. Per CMS “when a beneficiary enters a hospital for a surgical procedure not designated as an inpatient-only (IPO) procedure as described in 42 CFR 419.22(n), a diagnostic test, or any other treatment, and the physician expects to keep the beneficiary in the hospital for only a limited period of time that does not cross 2 midnights, the services would be generally inappropriate under Medicare Part A.”

 

Additionally, CMS has consistently indicated that “removal of a service from the IPO list has never meant that a beneficiary cannot receive the service as a hospital inpatient – as always, the physician should use his or her complex medical judgment to determine the generally appropriate setting.”

 

So, what exactly does this mean? It means that when a surgical procedure has been removed from the IPO List, if you admit a patient as an inpatient for a surgical procedure not on the IPO list, documentation in the record must support the need for the inpatient admission.

In the CY 2020 OPPS Final Rule, CMS finalized a two-year exemption from site-of-service claim denials, Beneficiary and Family Centered Care Quality Improvement Organization (BFCC-QIO) referrals to RACs, and RAC reviews for “patient status” (that is, site-of-service) for procedures that are removed from the IPO list under the OPPS beginning on January 1, 2020.

For CY 2021, CMS proposed to continue the two-year exemption for procedures removed from the IPO list beginning on January 1, 2021. They also requested comments on whether this continues to be the appropriate time frame, or if a longer or shorter period may be warranted.

Ultimately, CMS finalized a policy where procedures removed from the IPO list beginning January 1, 2021 “will be indefinitely exempted from site-of-service claim denials under Medicare Part A, eligibility for Beneficiary and Family-Centered Care-Quality Improvement Organization (BFCC-QIO) referrals to Recovery Audit Contractors (RACs) for noncompliance with the 2-midnight rule, and RAC reviews for “patient status.”

CMS plans to maintain this exemption until they “have Medicare claims data indicating that the procedure is more commonly performed in the outpatient setting than the inpatient setting.”

As a provider, it is important to be mindful that this exemption is specific to site-of-service claim denials. This exemption does not include medical necessity based on a National or Local Coverage Determinations (NCDs and LCDs). Ultimately, irrespective of site-of-service, a short stay claim can still be denied for lack of documentation supporting medical necessity of the surgical procedure.

Hospital Outpatient Department Prior Authorization Program: Proposed New Service Categories

With the CY 2020 OPPS/ASC Final Rule (CMS-17-17-FC), CMS established the nationwide prior authorization process and requirements for certain hospital outpatient department (OPD) services.  Effective July 1, 2020 blepharoplasty, botulinum toxin injections, panniculectomy, rhinoplasty, and vein ablation all required a prior authorization.  

CMS indicates in the CY 2021 OPPS final rule that they received over 100 comments to their proposal to add cervical fusion with disc removal and implanted spinal neurostimulators to this program effective for services provided on or after July 1, 2021.

Several commenters expressed the concern “that the MACs have not demonstrated the ability to handle the volume of prior authorization requests since the OPD process began July 1, 2020. These commenters stated that MACs have taken longer than the 10 days specified for communicating the results of prior authorization requests.” CMS responded by acknowledging “there have been occasions when a few of the MACs were not able to issue decisions within this timeframe, as they adjusted to this new workload.” They went on to indicate they have worked with the MACs to ensure outstanding requests were resolved as soon as possible and “as this program continues, we will continue tracking MAC timeliness metrics and are confident that the MACs will be able to meet the required review and decisions timeframes so as not to cause additional burden for OPD providers or delay medically necessary services.” Only time will tell.

Ultimately, CMS finalized their proposal without modifications. Table 74 of the final rule includes the overall list of outpatient department services that will require a prior authorization. Following are the new procedure codes effective July 1, 2021.

Cervical Fusion with Disc Removal

  • 22551: Fusion of spine bones with removal of disc at upper spinal column, anterior approach, complex, initial, and
  • 22552: Fusion of spine bones with removal of disc in upper spinal column below second vertebra of neck, anterior approach, each additional interspace

Implanted Spinal Neurostimulators

  • 63650: Implantation of spinal neurostimulator electrodes, accessed through the skin,
  • 63685: Insertion or replacement of spinal neurostimulator pulse generator or receiver, and
  • 63688: Revision or removal of implanted spinal neurostimulator pulse generator or receiver

Timely to the concerns raised about this Medicare Fee-for-Service prior authorization program, on December 2nd, the American Hospital Association (AHA) published the document Addressing Commercial Health Plan Abuses to Ensure Fair Coverage for Patients and Providers.  The AHA notes that “Inappropriate use of prior authorization can negatively impact the quality of care. A survey of more than 1,000 physicians found that more than 90 percent of respondents said prior authorization “had a significant or somewhat negative clinical impact, with 28 percent reporting that prior authorization had led to a serious adverse event such as a death, hospitalization, disability or permanent bodily damage, or other life-threatening event for a patient in their care.”
