Analysis based on CMS's July 31 CJR-X final rule, press release, model guidance, and prior CJR evaluation findings, with AOTA acute-care guidance for occupational therapy context.
CMS has taken the familiar joint-replacement bundle out of its regional laboratory and put it on a national map. Starting January 1, 2028, most eligible acute care hospitals will answer for Medicare spending and quality from a hip, knee, or ankle replacement through 90 days after discharge. The surgeon's work opens the episode. The hospital's financial responsibility follows the patient into home health, outpatient therapy, skilled nursing, and ordinary life. For occupational therapy, the decisive question is whether the discharge plan can withstand a kitchen, a bathroom, a caregiver's schedule, and a bad Tuesday.
In brief
- CJR-X will be mandatory for most eligible hospitals nationwide and will cover related Medicare Part A and Part B spending through 90 days after a qualifying joint-replacement discharge.
- CMS explicitly recognized occupational therapists as important to discharge planning and said decisions should account for functional status, rehabilitation needs, the home environment, caregiver availability, and patient preference.
- CMS declined to change Medicare's home-health qualifying-service or assessment rules for OT, while finalizing separate home-visit, telehealth, and skilled-nursing flexibilities inside the model.
A national bundle with a long memory
CJR-X, short for Comprehensive Care for Joint Replacement Expanded, will become the first nationwide mandatory test of an episode-based Medicare payment model. It covers qualifying hip, knee, and ankle replacements performed in inpatient and hospital outpatient settings for people in Original Medicare. The episode begins with the procedure and keeps running for 90 days after discharge.
Most hospitals paid under the Inpatient Prospective Payment System and also paid under the outpatient system will participate. Hospitals already in the Transforming Episode Accountability Model, Maryland hospitals, and some facilities outside those payment systems are exempt. TEAM uses a 30-day episode and includes several surgeries; CJR-X keeps its attention on lower-extremity joint replacement for three times as long.
One CMS webpage currently displays an October 1, 2027 start. The final rule's executive summary and CMS's same-day announcement both state January 1, 2028. Until the agency reconciles those pages, hospitals should plan from the final-rule date and watch the model site for a correction. The disagreement is a calendar problem, not a reason to postpone the operational work.
The hospital's spreadsheet follows the patient home
Medicare will continue paying every provider and supplier through the usual payment system. After a performance year, CMS will compare the episode's actual spending with the hospital's target price. Quality and spending results determine whether the hospital receives a reconciliation payment or owes money back. The bundle therefore lives behind the claims, where it can still influence the referral, the length of a post-acute stay, and the intensity of follow-up.
CMS is expanding the model after its predecessor produced an estimated $112.7 million in net Medicare savings for more than 98,000 hip and knee replacement patients at 323 hospitals during 2021 through 2023. Claims-based measures showed no loss of quality. CMS says lower post-acute spending supplied most of the savings.
That last finding deserves a highlighter. Home health, skilled nursing, outpatient therapy, and rehabilitation facilities occupy the portion of the episode where hospitals have already found the largest economies. A lower-cost setting can be the right setting. A thinner service plan can also fail when it ignores cognition, self-care, the home layout, caregiver capacity, or the practical demands of living alone. The model gives hospitals a financial reason to know the difference.
CMS named the functional questions, and OT
Commenters asked CMS to require occupational therapists in joint-replacement discharge decisions. The agency declined to prescribe one staffing model for every hospital, then described the judgment those teams must make. Post-acute decisions should account for the patient's medical condition, functional status, rehabilitation needs, home environment, caregiver availability, preferences, and other individual circumstances.
CMS also recognized occupational therapists, physical therapists, physiatrists, and other rehabilitation professionals as important to recovery. It expects hospitals to involve the clinical expertise appropriate to the beneficiary when arranging rehabilitation, coordinating post-acute care, and handling medically complex cases. That is a useful invitation with no automatic seat assignment attached.
OT departments will have to make the seat useful enough that joint-replacement programs keep pulling it to the table. A clear evaluation should connect dressing, bathing, toileting, meal preparation, medication routines, cognition, equipment, transportation, and caregiver demands to a safe destination. A generic recommendation gives the bundle little to work with. A functional account can explain why home is realistic, why a facility is necessary, or which services must arrive quickly after discharge.
Patient choice remains a guardrail
Hospitals may build relationships with preferred post-acute providers and share information about performance. They cannot require a patient to use a particular agency, clinic, or facility. CJR-X preserves access to medically necessary covered care and the beneficiary's freedom to choose Medicare-participating providers and suppliers.
CMS is also keeping model-specific notices. Hospitals must tell affected patients about the model and their rights, and providers with a financial relationship to the hospital must disclose it. That paperwork matters because a nationwide bundle can make a preferred network feel like the only network unless the patient hears otherwise.
Occupational therapy documentation can make the guardrail visible. Record the patient's goals and preferences, the home and caregiver facts, the options discussed, and the clinical basis for the recommended level of care. When cost pressure and clinical judgment point in different directions, a functional record gives the team something sturdier than an assertion.
The home-health request stopped at the door
Some commenters asked CMS to let occupational therapy qualify a patient for the Medicare home health benefit and to permit rehabilitation therapists to perform home health assessments when therapy and nursing are ordered. CMS praised therapists' role in functional recovery and safe transitions, then declined the request. The agency said home-health eligibility, qualifying services, and assessment requirements sit in separate Medicare rules and may be considered in future rulemaking.
CJR-X does create a narrower home option. A beneficiary who does not qualify for Medicare home health may receive up to nine post-discharge visits from clinical staff under the general supervision of a physician or nonphysician practitioner. The new service can address safety, fall risk, functional status, daily activities, medication routines, adherence, education, and links to community services. The final regulation defines clinical staff according to law, facility policy, supervision, and the specific service; it does not create an independent OT billing benefit. Organizations will need a compliant staffing and billing design before assigning those visits.
CMS also finalized telehealth flexibilities and a waiver of the usual three-day hospital-stay requirement for qualifying skilled-nursing care, subject to model conditions. Those tools expand the care-pathway menu. Existing Medicare coverage rules still govern the therapy a patient needs, and CMS says it will monitor for premature discharge, steering, and reductions in medically necessary care.
Quality has five chances to interrupt the savings story
A hospital must clear a minimum composite quality score before it can receive a positive reconciliation payment. CJR-X will use five measures covering complications after elective hip and knee replacement, hospital visits within seven days of outpatient surgery, inpatient experience, outpatient surgical experience, and patient-reported outcomes after hip or knee replacement.
There is no OT-specific measure in that group. OT work can still reach several of the outcomes the model values: a home routine the patient can manage, caregiver training that survives discharge, equipment that arrives in time, warning signs the patient understands, and a transition that does not bounce back through the emergency department. Patient-reported outcomes also make the person's account of recovery part of the payment conversation.
Quality measures cannot see every missed shower, unsafe transfer, abandoned meal, or exhausted caregiver. Hospitals should add operating measures that can: time from discharge to the first therapy contact, failed referrals, equipment delays, changes in recommended destination, unplanned calls, and functional goals carried across settings. The 90-day clock is long enough for small handoff failures to become expensive ones.
What OT and rehabilitation leaders should do now
First, determine which model will govern the hospital. A TEAM participant stays outside CJR-X while TEAM is active; another eligible hospital should expect CJR-X. Ask who owns joint-replacement episodes, target-price data, quality reporting, beneficiary notices, post-acute relationships, and care-redesign meetings. OT needs a named route into each of those conversations.
Next, test the pathway with real patients. Follow an elective knee replacement, a hip fracture case, a patient living alone, and a patient with cognitive or caregiver complications from the preoperative screen through 90 days. Check whether functional findings travel with the referral, whether the receiving provider accepts it promptly, and whether the chosen outcome measure appears again after discharge.
Post-acute providers should bring hospitals more than a promise of good care. Bring access times, acceptance rates, functional outcomes, readmissions, missed visits, equipment coordination, rural reach, and the process for escalating a failing home plan. Acute-care OT teams should bring the details that predict whether the plan will work outside the hospital. CJR-X turns those details into part of a national payment model. They were already the substance of a safe recovery.
