Who is Responsible for Prior Authorization? (Provider vs. Payer vs. Patient)

Patients ask it at the front desk every week: "Isn't my insurance supposed to handle this?" The short answer is no — in nearly every case the provider's office is responsible for obtaining prior authorization, not the patient and not the payer. Here's how the responsibility actually breaks down, and why most independent practices end up doing more than their fair share.

The provider's office owns the process

When a service requires prior authorization, the rendering provider — the physician, clinic, imaging center, or specialty practice that will deliver the care — is the party contractually responsible for requesting it. That means verifying eligibility, confirming whether a PA is required for the specific CPT code, gathering clinical documentation, submitting the request through the payer's portal/fax/API, and following up until a decision is rendered.

What the payer is (and isn't) responsible for

Payers are responsible for publishing their PA requirements, accepting standardized requests, and rendering a decision within the timelines set by their plan and applicable regulations (in 2026, CMS-0057-F requires 7 days for standard and 72 hours for urgent on impacted plans). They are not responsible for initiating the request or assembling the clinical record.

What patients are responsible for

• Providing accurate insurance information at intake.
• Disclosing other coverage (secondary insurance, workers' comp, MVA).
• Signing required consents and ABNs.
• Filing a member appeal if a denial stands after the provider's appeal.

Patients are not expected to chase prior authorizations — and asking them to do so usually delays care and damages the relationship.

Where most practices get stuck

Because the provider owns the process, the cost lands inside the practice: dedicated staff time, denials from missing documentation, last-minute reschedules, and lost revenue when authorizations expire. MGMA surveys consistently show PA as the #1 administrative burden in independent practice.

The outsourcing alternative

Outsourcing prior authorization moves the responsibility off your front office and onto a dedicated specialist whose only job is approvals. A good partner will verify eligibility before the visit, prepare documentation to each payer's specific medical-necessity criteria, submit through the correct channel, follow up daily, and manage denials and appeals end-to-end.

The responsibility doesn't shift to the payer or the patient — it stays with the provider. But the work, the burnout, and the revenue leakage no longer have to.
