A reference guide to the OB/GYN procedures most likely to require prior authorization, and how to avoid authorization-related denials.
Prior authorization requirements vary by payer, but certain categories of OB/GYN procedures are consistently likely to require it, and missing this step is one of the [top denial reasons](/blog/top-obgyn-denial-reasons) practices deal with.
Surgical Procedures
Most non-emergent gynecological surgeries — hysterectomy, myomectomy, and many pelvic floor repair procedures — typically require prior authorization from commercial payers. Emergency procedures are generally exempt, but the definition of "emergency" for authorization purposes is narrower than clinical urgency might suggest, so it's worth confirming rather than assuming.
Infertility Treatment
Nearly every step of infertility treatment, from diagnostic workup through IVF cycles, often requires separate authorization at each stage. Our [infertility billing challenges](/blog/infertility-billing-challenges) guide covers this in more depth.
Advanced Imaging
Certain advanced imaging ordered in an OB/GYN context — beyond routine obstetric ultrasound — frequently requires authorization, and this requirement is easy to miss since routine ultrasounds typically don't need it, creating an inconsistent expectation across visit types.
Building an Authorization Checklist by Payer
Because requirements vary so much, the most reliable approach is a payer-specific checklist reviewed and updated periodically, rather than relying on staff memory or assuming last year's requirements still apply.
Key Takeaways
- ›Non-emergent surgery, infertility treatment, and advanced imaging are the highest-risk categories
- ›"Emergency" exemptions are narrower than general clinical urgency
- ›Authorization requirements should be tracked per payer and reviewed periodically, not assumed
Missing a required authorization is one of the more frustrating denial types because the medical necessity usually isn't in question — it's a pure process gap. Our [eligibility verification](/eligibility-verification) and [denial management](/denial-management) services both address this from different angles — prevention and recovery.
