On July 15, 2025, the Facilities for Medicare & Medicaid Service (CMS) issued a proposed rule for the Calendar 12 months (CY) 2026 Outpatient Potential Cost System (OPPS). As a part of the proposed rule, CMS outlines a plan to eradicate the Inpatient Solely (IPO) record over a three-year interval, starting with the elimination of 285 procedures in 2026. The preliminary group faraway from the record contains principally musculoskeletal providers, together with 16 non-musculoskeletal procedures spanning cardiovascular, lymphatic, digestive, gynecological, and endovascular classes. Though CMS said that these procedures will initially stay exempt from medical overview underneath the Two-Midnight Rule, that exemption will apply solely till Medicare claims knowledge exhibits they’re extra generally carried out in outpatient settings. The proposal displays a broader shift towards extra restrictive oversight of inpatient utilization.
Created by CMS in 2000, the IPO record features a fluctuating record of 1,700 to 1,800 high-risk procedures deemed too advanced for outpatient care and which aren’t payable underneath the OPPS. CMS beforehand tried to eradicate the IPO record in 2021 however reversed course within the CY 2022 OPPS Remaining Rule. CMS cited “a lot of stakeholder feedback all through the CY 2021 rulemaking cycle and following issuance of the ultimate rule with remark interval that opposed the elimination of the IPO record primarily attributable to affected person security issues, stating that the IPO record serves as an vital programmatic safeguard.” The reversal mirrored issues that eradicating the IPO record would result in inappropriate site-of-service denials and create pointless administrative burden for hospitals and clinicians managing advanced procedures.
The proposed elimination of the IPO record would introduce new reimbursement danger by changing categorical protections with case-by-case determinations. With out the protections of the IPO record, physicians can be anticipated to foretell upfront potential problems to justify inpatient admission, whereas utilization overview groups face elevated documentation calls for and scrutiny. If the proposal is finalized, hospitals might see a rise in post-payment audits, reimbursement denials, and appeals.
Administrative burden elevated instantly following the elimination of complete hip arthroplasty (THA) and complete knee arthroplasty (TKA) from the IPO record in 2018. A 2020 survey of the American Affiliation of Hip and Knee Surgeons discovered that 81% of surgeons reported higher administrative workload, 54% reported needing to acquire preauthorization or attraction a denial of preauthorization for inpatient admissions at the least month-to-month, and 61% had sufferers contact them over sudden copayments when surgical procedures had been billed outpatient. 10% had already undergone audits associated to inpatient standing regardless of CMS’s preliminary audit moratorium.
Monetary financial savings had been a serious driver behind CMS’s resolution to take away THA and TKA from the IPO record. Research present that outpatient TKA value CMS roughly $8,527 lower than prolonged inpatient stays of three–4 days and $3,155 lower than inpatient admissions general. By 2020, 57.2% of Medicare TKA sufferers had been categorised as outpatients, and 72% of these outpatients nonetheless remained within the hospital for greater than 24 hours (common size of keep 2.7 days). In contrast with inpatient TKAs, outpatients had been discharged to expert nursing services extra regularly (3.1% vs. 2.0%), had extra emergency division visits (5.1% vs. 3.9%), and had larger 90-day readmission charges (2.2% vs. 0.9%). One other research discovered that about one-third of TKA sufferers booked for outpatient surgical procedure stayed longer than 48 hours however had been nonetheless billed as outpatient, resulting in underpayment and misplaced reimbursement regardless of resource-intensive hospital stays.
Elimination from the IPO record shifts extra circumstances into outpatient or commentary standing, affecting each affected person out-of-pocket prices and entry to post-acute care. Inpatient stays are billed underneath Medicare Half A, which covers most hospital prices and expert nursing facility care after discharge. Remark stays fall underneath Medicare Half B, which requires sufferers to pay 20% coinsurance for all hospital and doctor providers and doesn’t cowl post-acute expert nursing care. Researchers discovered that pushing revision TKA and THA procedures to outpatient ends in pointless affected person copayments, exclusion from bundled cost packages, and restricted entry to post-acute care sources corresponding to rehabilitation services and residential well being providers.
The monetary pressure of IPO removals is illustrated by a single-hospital research of the Bundled Funds for Care Enchancment (BPCI) program after TKA was faraway from the IPO record. Hospital directors modified 25% of Medicare TKA admissions to commentary standing, disqualifying these circumstances from BPCI and leading to an estimated $24,332 loss in financial savings to the physician-owned bundle. The research projected that if 50% of TKA circumstances had been moved to commentary, the bundle would not be financially viable. Analysis additionally warns that as lower-risk sufferers shift outpatient, remaining inpatients can be extra medically advanced, driving up post-acute prices and additional eroding financial savings. Comparable issues have been raised for advanced revisions, the place excessive implant prices, longer restoration instances, and exclusion from bundled cost packages might make these circumstances financially unsustainable for hospitals.
Shifting extra circumstances outpatient discouraged surgical procedure for sufferers with comorbidities who’re poor candidates for same-day discharge, concentrating the sickest, most resource-intensive sufferers in fewer hospitals. A cohort research discovered that following the elimination of TKA from the IPO record elimination, older, Black, and feminine sufferers, in addition to sufferers at safety-net hospitals, had been much less more likely to obtain outpatient TKAs. State-level knowledge from New York equally confirmed that sufferers with vital comorbidities had been far much less more likely to endure complete hip or knee alternative in ambulatory surgical procedure facilities (ASCs) in comparison with hospital inpatient departments, reflecting surgeon choice patterns that restrict ASC entry for sicker sufferers.
Whereas research replicate outcomes from the elimination of choose orthopedic procedures, the present CMS proposal contemplates eliminating all the IPO record, affecting a far broader vary of advanced surgical procedures. If these patterns maintain, the implications, monetary pressure, lowered entry for medically advanced and marginalized sufferers, and elevated administrative burden, are more likely to be amplified.
As CMS finalizes this coverage, suppliers ought to concentrate on the fast compliance and reimbursement dangers related to the phase-out. The proposed rule is open for public remark by means of September 15, 2025.
