Why prior authorizations get delayed, and how to stop it

The uncomfortable part first

Payers are slow and their portals are bad. Both true. But when a practice tracks the reason each authorization stalled, most of the delay turns out to be ours: a request submitted without the clinical the payer always asks for, sent to the wrong entity, or never followed up after the first submission.

The eight causes, in the order they occur

1. Nobody knew one was required

Requirements change quarterly and are not announced to practices. A service authorized without question last year now needs one. This is the most expensive cause because it is discovered after the service, when nothing can be done.

2. Sent to the wrong entity

Radiology, behavioural health, laboratory and specialty drugs are frequently carved out to a separate vendor. A request sent to the health plan for a carved-out service is not slow, it is in the wrong place.

3. Submitted without the clinical the payer always wants

Every payer has a list of what it needs for a given service, and it is usually knowable in advance. Submitting without it guarantees a request for information and adds a week.

4. The diagnosis does not meet the coverage policy

Not a delay so much as a refusal in slow motion. If the policy lists covered indications and the submitted diagnosis is not among them, no amount of chasing changes the outcome.

5. Nobody followed up

The single largest cause in most practices. A request was submitted, a confirmation number received, and nothing happened again until the patient rang. Authorizations do not chase themselves.

6. A peer-to-peer window was offered and missed

When a request is pended, many payers offer a peer-to-peer review with a short window. It is the strongest route available and it closes fast, usually without anybody at the practice noticing it opened.

7. The provider on the request is not the provider who will perform

An authorization is often specific to the rendering provider and the facility. A last-minute change to either invalidates it, and the claim denies for an authorization that genuinely exists.

8. It expired

Authorizations have date ranges and unit counts. A course of treatment that runs past either denies from that point onward, and the denial is usually unappealable because the service already happened.

What actually fixes it

A tracked queue with a named owner, a per-payer note of what each request needs, and a follow-up cadence measured in days rather than weeks. That is the whole intervention, and it is more effective than any technology.

Record four things on every authorization the moment it is granted: the codes it covers, the rendering provider, the date range and the unit count. Every one of those is a way the authorization stops matching the claim, and all four are free to record and expensive to discover.
