Prior authorization has long been one of the most friction-heavy processes in healthcare. For health plans and pharmacy benefit managers, it sits at the intersection of clinical judgment, regulatory compliance, and operational throughput. For years, most of that work has run through manual review, fax queues, and phone calls between payers and prescribers.
That's changing. As authorization volumes grow and CMS compliance requirements tighten, automation is shifting from a nice-to-have to a baseline expectation for utilization management (UM) programs.
A traditional prior authorization workflow requires staff to manually review clinical criteria,
cross-check formulary rules, and route requests between pharmacy and medical teams. Each of those handoffs adds time, and every extra day of review is a day a patient waits for care or a prescriber waits for a decision.
Manual review also makes it harder to scale. As health plans take on more lives and more complex specialty and medical benefit authorizations, staffing a growing request volume with manual reviewers becomes both expensive and difficult to sustain.
The most effective UM automation isn't about removing clinical judgment from the process. It's about removing the parts of the workflow that don't need a person. That includes:
Automatically applying payer-specific clinical criteria to route straightforward requests for auto-adjudication, while flagging genuinely ambiguous cases for clinical review.
Unifying medical and pharmacy authorization workflows so reviewers aren't working across disconnected systems for a single patient's care.
Giving prescribers and specialty pharmacies electronic submission options (ePA) instead of fax- and phone-based intake, which cuts turnaround time and reduces transcription errors.
Surfacing audit-ready documentation automatically, rather than reconstructing it after the fact when CMS or a health plan's compliance team comes calling.
Done well, this keeps humans in the loop for the decisions that actually require clinical expertise, while clearing the administrative backlog around them.
CMS-0057-F has raised the bar further, requiring payers to build faster, more transparent, and more interoperable prior authorization processes, including tighter decision timeframes and API-based data exchange. For UM teams still running largely manual workflows, that's a real deadline pressure, not just a technology upgrade decision.
Not every automation approach is built for the complexity of a modern health plan or PBM. The right platform needs to handle both medical and pharmacy authorizations in one system, apply configurable clinical criteria rather than a one-size-fits-all rules engine, and keep pace with CMS reporting and audit requirements as they evolve.
Agadia, whose PAHub platform is used by health plans and PBMs to manage prior authorization, formulary administration, appeals and grievances, and Part D Star Ratings compliance, is one example of a vendor built specifically around that unified
medical-and-pharmacy UM workflow rather than a general-purpose claims or intake tool.
The organizations that get ahead of CMS-0057-F and rising authorization volumes will be the ones that treat automation as core infrastructure, not a bolt-on. That means unifying medical and pharmacy UM, keeping clinical staff focused on the decisions that need them, and building the audit trail into the workflow itself rather than reconstructing it after the fact.
For health plans and PBMs evaluating where to start, the highest-leverage first step is usually the same one driving most of the administrative burden today: prior authorization.
