Ask any practice what wastes the most time for the least benefit, and prior authorization will be near the top of the list. Staff spend hours on the phone and on portals, care gets delayed, and a meaningful share of requests get denied on the first pass for reasons that have nothing to do with whether the care is appropriate.
The rules are changing
The federal CMS interoperability and prior authorization rule, often referenced as CMS-0057, pushes affected payers toward electronic, standards-based prior authorization using modern data exchange. The point is to replace faxes and phone trees with structured requests that can be processed quickly and tracked. That regulatory floor makes automation far more practical than it was even a few years ago.
Where AI actually helps
The biggest wins are unglamorous. AI can read the payer's own policy, compare it against the patient's chart, and tell you before you submit whether the documentation supports approval. It can assemble the request, attach the right clinical evidence, and route it through the electronic channel. When something is missing, it can say so while the patient is still in front of you, instead of three days later when the denial arrives.
This shifts the work from chasing denials after the fact to preventing them up front. A denial that never happens costs nothing to appeal.
Keeping a human in the loop
Automation should speed up the routine and surface the exceptions, not make clinical decisions on its own. The sensible pattern is to let software handle the paperwork and the rule-checking, then put a person on the cases that are genuinely borderline. That keeps speed where speed is safe and keeps judgment where judgment is needed.
