How do critical access hospitals handle utilization review?
Short answer
Most critical access hospitals handle utilization review with one or two people who also cover case management and discharge planning, and usually no physician advisor on staff. The model that works is a clear screening process for every admission and observation case, plus on-call access to an outside physician advisor for status questions, peer-to-peer calls and appeals.

What's different about critical access hospitals
- Up to 25 inpatient beds, usually in rural areas
- An annual average length of stay of 96 hours or less for acute inpatients
- A physician must certify that an inpatient can reasonably be expected to be discharged or transferred within 96 hours, a condition of Medicare payment
- Swing beds for skilled care, which for Medicare need a qualifying 3-day inpatient stay
Common pressure points
- Medicare Advantage denials, often handled by staff with little time to fight them
- No physician to escalate status questions to, especially nights and weekends
- Long observation stays because no one is sure the case meets inpatient criteria
- Denials written off because there's no time to appeal
A practical setup
- Screen every admission and observation case within one business day using consistent criteria
- Escalate unclear cases the same day to a physician advisor by phone or text
- Hand peer-to-peer calls to the physician advisor instead of the attending
- Appeal clinical denials on a schedule, with the physician advisor writing or reviewing the argument
- Run a short monthly review of denials and observation cases to target documentation training
What to measure
- Observation rate and average observation hours
- Denial rate by payer and by reason
- Appeal and peer-to-peer overturn rates
- Average inpatient length of stay against the 96-hour limit

Common questions
Does a critical access hospital need a physician advisor on staff?
Usually not full-time. Most get the coverage they need from an external physician advisor service, reachable the same day by phone or text.
How do swing beds affect utilization review?
For Medicare to cover skilled care in a swing bed, the patient generally needs a qualifying 3-day inpatient stay first. Observation days don't count, so status decisions directly affect swing-bed eligibility.
