The Growing Prior Authorization Burden
As Medicare Advantage enrollment has grown, prior authorization has become a routine operational challenge for home health agencies. CMS data shows that MA plans collectively denied 6% of prior authorization requests in 2023, but the burden extends beyond outright denials. Requests requiring supplemental documentation, plan medical director reviews, and peer-to-peer calls consume significant clinical and administrative time before authorization is granted.
For home health agencies, the timing dimension of prior authorization is particularly challenging. Patients discharged from hospitals or SNFs need home health services immediately—delays in authorization directly delay care and create patient safety concerns.
Building a Pre-Discharge Authorization Workflow
The most effective prior authorization management starts before a patient is admitted to home health services. High-performing agencies have established pre-discharge workflows with their primary hospital and SNF referral sources—protocols that initiate the authorization request while the patient is still in the facility, ensuring authorization is in hand before the first home health visit.
Agencies that have implemented pre-discharge authorization workflows report 70–80% reduction in authorization-related admission delays.
Documentation That Gets Authorizations Approved
Prior authorization denials most frequently occur because the clinical documentation submitted does not clearly establish medical necessity under the plan’s specific criteria. The supporting documentation for authorization requests must address three elements: homebound status established through specific functional limitations, skilled care need demonstrated through clinical complexity, and an appropriate plan of care that matches the services being requested.
Building plan-specific authorization templates—pre-populated with the language and clinical elements each plan’s reviewers look for—dramatically improves first-submission approval rates.
Peer-to-Peer Review: When and How to Use It
When a prior authorization request is denied, most MA plans offer a peer-to-peer review process in which your clinical team can speak directly with the plan’s medical director. Peer-to-peer reviews succeed at significantly higher rates than written appeals when conducted by clinicians who are prepared with the right clinical arguments.
Effective peer-to-peer reviews are concise, clinically focused, and prepared in advance. Agencies that develop standard peer-to-peer scripts for their most common service types report peer-to-peer approval rates above 70%.
