The short version: prior authorization is a payer's approval, obtained before care is delivered, confirming they'll cover it. Skip it or get it wrong, and the claim gets denied after the resident has already received weeks of care. The facility eats the cost.
In long-term care this is sharper than in most settings, because admissions often happen fast. A hospital discharge planner calls on a Friday afternoon, the bed is available, and the facility says yes before anyone has confirmed whether the payer will authorize the stay, for how many days, and under what level of care.
The three failure points
Authorizing the admission but not the continued stay. Initial approval covers a set number of days. Nobody tracks the expiry. Day 15 arrives, the extension request goes in late, and the payer denies the gap.
Treating auth as a billing task. It isn't. It's a clinical documentation task with a billing consequence. If the person requesting the authorization can't speak to the MDS and the care plan, the request gets kicked back.
No single owner. In facilities under 50 beds, prior auth usually lives in the gap between the admissions coordinator, the DON, and the biller. Work that belongs to three people belongs to none of them.
What good looks like
A working process has a named owner, a tracked expiry date for every active authorization, and a standing review before any Medicaid-pending admission is accepted. That review should answer one question honestly: if this application is denied, what does the facility lose?
Facilities that don't have the staff to run this internally typically hand it off. Prior authorization management for SNF admissions is one of the more common back-office functions to outsource, precisely because it's high-consequence and low-volume enough that a dedicated in-house hire is hard to justify.
LTCPro handles this alongside billing, AR, payroll, and general ledger work for Skilled Nursing and Assisted Living operators, which matters more than it sounds. When authorization and billing sit with the same team, the expiry tracking and the claim submission stop being two disconnected workflows.
The measurement that matters
Track your denial rate specifically for authorization-related denials, separate from coding and eligibility denials. Most facilities report a single blended denial number, which hides exactly where the problem is. Split it out for one quarter and the answer usually becomes obvious.
