Monitor payer policy activity
Defines medical necessity, documentation, admission, and physician/therapy requirements for coverage of services in an inpatient rehabilitation facility (IRF) for Blue Cross & Blue Shield of Rhode Island products. Affects providers admitting or treating members in IRFs.
No material clinical or coverage changes in this revision.
Coverage criteria for inpatient rehabilitation facility (IRF) services
IRF admission medical necessity
Covered when ALL of the following are met:
Core admission requirements
- Therapy disciplines: Active and ongoing therapeutic intervention of multiple therapy disciplines (documentation that at least one discipline is physical therapy or occupational therapy; may include speech-language pathology or prosthetics/orthotics).
Documented in preadmission screening and IRF medical record
- Intensity of therapy: Either ≥3 hours of therapy per day on ≥5 days per week OR ≥15 hours of therapy within a 7-consecutive-calendar-day period beginning on the date of admission.See thresholds
Required therapy treatments must begin within 36 hours from midnight of the day of admission; brief interruptions ≤3 consecutive days may be allowed with documentation.
- Physician supervision: Rehabilitation physician involvement with at least 3 face-to-face visits per week throughout the stay; beginning in week 2, a qualified non-physician practitioner may conduct one of the three weekly visits if within scope of practice.>=3 visits/week
First week requires physician to visit minimum three times; visits documented in IRF medical record
- Documentation: Preadmission screening within 48 hours immediately preceding admission (or updated within 48 hours), overall plan of care completed within first 4 days, admission orders, IRF-PAI, and documentation of prior function, expected improvement and length of time, risk for complications, treatments required, and anticipated discharge destination.
Detailed documentation required to support medical necessity
Typical goal is safe return to home or community; document nature, degree, and expected timeframe of improvement
IRF admission and treatment criteria
Covered when ALL of the following are met
Supported by preadmission screening, post-admission physician evaluation, and overall plan of care
Team may be led in person or remotely; documentation should record participants and decisions
Visits emphasize interaction of medical and functional goals and modification of treatment
Typical goal is safe return to home or community
Plan of care must support medical necessity and be retained in the IRF medical record
An IRF stay is not covered when the patient's condition can be appropriately managed in a less intensive setting (for example, a skilled nursing facility or outpatient facility). The policy emphasizes that the primary distinction supporting IRF coverage is the need for the high level of physician supervision and intensive rehabilitation services that are not delivered in lower-acuity settings. If the clinical presentation and required services do not meet that threshold, coverage for an IRF admission is not indicated.
An IRF stay is not reasonable and necessary when the complexity of the patient’s nursing, medical management, and rehabilitation needs does not require an inpatient interdisciplinary team approach. The policy requires a documented expectation at admission that those complexities can only be addressed through periodic interdisciplinary team conferences (at least once weekly) and coordinated interventions by the required disciplines; absent that necessity, IRF-level care is not appropriate.
Admission to an IRF is not medically necessary when the patient’s condition can be managed safely and effectively in a less intensive setting (such as a SNF or outpatient facility). The overall plan of care must be completed within the first 4 days and must support that inpatient IRF services are required; if the plan of care or preadmission evaluation indicates the expected intensity, frequency, and duration of therapies can be delivered outside an IRF, admission should not be authorized.
Care is not appropriate for IRF level of care when the IRF medical record does not document a reasonable expectation that measurable, practical improvement in the patient’s functional condition can be achieved within a predetermined, reasonable period. The record must describe the nature and degree of expected improvement and the anticipated timeframe; without this reasonable expectation of measurable functional gain, IRF admission is not indicated.
Coding, therapy intensity, and visit requirements
| No codes listed |
Provider responsibilities, documentation, and authorization
Prior authorization requirement
Prior authorization must be obtained for Medicare Advantage members; prior authorization is recommended (but not required) for Commercial products.
Admission documentation of complexity and expected improvement
At the time of admission document that the complexity of the patient's nursing, medical management, and rehabilitation needs necessitates an inpatient stay and an interdisciplinary team approach, and that there is a reasonable expectation measurable functional improvement can be achieved within a predetermined, reasonable period.
Therapy intensity and initiation timing
Document an expectation of intensive therapy (either generally ≥3 hours/day on ≥5 days/week or ≥15 hours within a 7-consecutive-day period) and ensure required therapy treatments begin within 36 hours from midnight of admission (therapy evaluations count toward this requirement).
Required admission documentation and forms
Ensure the IRF admission is supported by a detailed preadmission screening and an overall plan of care completed within the first 4 days of admission; include admission orders and the IRF-PAI in the medical record.
- Preadmission screening within 48 hours (or updated within 48 hours) documenting prior function, expected improvement and length of time, risk for complications, treatments needed, and anticipated discharge destination.
- Overall plan of care completed within first 4 days detailing expected intensity, frequency, duration of therapies, medical prognosis, and anticipated discharge destination.
- Include admission orders and the IRF-PAI forms in the medical record.
Document physician visits and interdisciplinary conferences
Document face-to-face rehabilitation physician and qualified non-physician practitioner visits in the IRF medical record and record weekly interdisciplinary team conferences including participants, the rehabilitation physician's concurrence, decisions made, and documentation of the nature, degree, and expected timeframe for measurable functional improvement.
- Rehabilitation physician visits should generally occur at least three times per week and be recorded in the medical record.
- Interdisciplinary team conferences must occur at least once per week and documentation should list participants and the physician's concurrence.
- Document the expected nature, degree, and timeframe of measurable functional improvement.
Medicare coverage note
Coverage applies only when the policy’s medical criteria are met; Medicare coverage or criteria changes supersede this policy and will be applicable to Medicare Advantage members.
Triggers for denial if required documentation is missing
Failure to document required rehabilitation physician face-to-face visits (generally at least three times per week), absence of documented weekly interdisciplinary team conferences with physician concurrence, or lack of documentation showing a reasonable expectation of measurable functional improvement within a reasonable period may trigger denial of coverage.
- Missing or undocumented ≥3 weekly rehabilitation physician visits.
- No record of weekly interdisciplinary team conferences or missing documentation of participants and physician concurrence.
- No documentation of expected measurable improvement (nature, degree, and expected timeframe).
Admission criteria and preadmission requirements
IRF — admission criteria (1 top-level node)
Preadmission screening and plan of care are required documentation
IRF — admission criteria (2 top-level nodes)
Supported by preadmission screening and post-admission physician evaluation
Documentation should include participants and decisions
Criteria for continued IRF stay
IRF — continued stay criteria (1 top-level node)
Document interruptions and justification in IRF medical record; therapy evaluations count toward intensity
IRF — continued stay criteria (3 top-level nodes)
Beginning in week 2, a qualified non-physician practitioner may conduct one of the three weekly visits if within scope of practice
Documentation should include participants and decisions; signatures not required except physician concurrence
Typical discharge objective is safe return to home/community
Discharge planning and criteria
The overall plan of care should document anticipated discharge destination and expected functional outcomes, and discharge is appropriate when those goals are achieved or when the patient no longer requires IRF-level interdisciplinary and physician-supervised intensive services.
Patients should be discharged when rehabilitation goals have been met or when further measurable improvement is unlikely within a reasonable time. Documentation must support that goals are achieved or that transfer to another appropriate level of care (typically home or community) is indicated.
Definitions used in this policy
Background and scope
Inpatient Rehabilitation Facilities (IRFs) provide intensive rehabilitation therapy in a resource-intensive inpatient hospital environment for patients with medically complex or unstable problems who require close physician supervision and a coordinated interdisciplinary team. IRFs are intended for patients whose nursing, medical management, and therapy needs are sufficiently complex that they cannot be met in less intensive settings; the typical goal of IRF treatment is a safe return to home or community, supported by documented, measurable functional improvement within a reasonable timeframe.
