Ending the 13 Hour Week: Automating Prior Authorization
According to the American Medical Association's most recent physician survey, the average practice completes close to 40 prior authorization requests per physician every week, consuming roughly 13 hours of physician and staff time. Ninety four percent of physicians say the process contributes directly to burnout.
Why this keeps costing you
Prior authorization has grown from an occasional check on high cost procedures into a routine gate on ordinary care, and the process is still largely manual: faxes, payer portals, phone holds, and forms that vary by insurer and procedure. Staff spend hours tracking down clinical justification from the chart, resubmitting rejected requests, and following up on approvals that should take minutes but take days. Every hour spent on this is an hour not spent on patients, and every delay is a delay in care a physician has already decided a patient needs.
How we build it
The intake agent parses the physician's order and matches it against payer specific criteria using a retrieval pipeline — a vector search over an indexed library of payer policy documents held in a Pinecone index — so the correct form and clinical criteria are pulled automatically instead of looked up by hand. The drafting agent then queries the EHR through the same integration layer used for documentation, extracting the specific diagnosis, prior treatments, and clinical rationale needed to justify the request, and pre fills the payer's exact form fields rather than a generic template. A submission agent manages delivery across whichever channel the payer actually requires — portal, fax, or API — and polls for status on a schedule, only interrupting staff when a request is denied or flagged for peer review.
What this looks like once it is running
- 1Automatic payer policy lookup so the correct requirements are used the first time
- 2Clinical justification drafted directly from existing chart data
- 3Cross channel submission and status tracking without manual follow up calls
- 4Staff alerted only on denials or genuine exceptions, not routine approvals
- 5AI assisted appeal letter drafting for denied requests, grounded in payer policy
Practices automating this workflow have reported cutting the administrative burden of prior authorization by roughly half, which for a multi physician practice can mean recovering dozens of staff hours every week — hours that go straight back into patient facing work instead of hold music.
