Prior authorization for ophthalmology, ENT, and oral surgery in one workflow

Eye, ENT, and oral surgery share a clinical cadence that is nearly opposite of cardiology: high-frequency, moderate-complexity, scheduled in blocks. A retinal clinic runs 100+ intravitreal injections a day; a pediatric ENT group books tonsillectomy and tube blocks weekly; an oral surgery practice runs wisdom teeth blocks most afternoons. The PA burden is volume-driven, not acuity-driven, and automation wins on the portal-navigation tax that human coordinators pay per submission.

Ophthalmology: cataract, retina, glaucoma

Cataract surgery (66984 standard, 66982 complex) is one of the highest-volume PA procedures in outpatient medicine. Medicare traditional rarely requires PA for cataract but Medicare Advantage plans almost universally do, and commercial plans vary. Payers want the Snellen visual acuity (usually 20/50 or worse in the operative eye), symptom impact on ADLs, and documentation that conservative management is insufficient. Premium lens upgrades are patient-pay and not PA-relevant, but the base procedure PA applies regardless.

Retinal procedures (67028 intravitreal injection, 67036 vitrectomy, 67038 membrane peel, 67108 retinal detachment repair) are PA-heavy. Vitrectomy requires OCT documentation, the specific indication, and previous treatment history. Glaucoma procedures (trabeculectomy, MIGS codes 65820, 0191T, 0474T, 66174 canaloplasty, iStent and Hydrus codes) require IOP documentation, medication trial history, and visual field progression.

Intravitreal injections and anti-VEGF PA

Intravitreal anti-VEGF therapy (Eylea, Lucentis, Vabysmo, Avastin off-label) is the highest-frequency PA in ophthalmology. Each injection (67028) is billed with a separate J-code for the drug (J0178 Eylea, J2778 Lucentis, J2779 Eylea HD, J2777 Vabysmo). PA requirements differ per drug, per eye, per schedule. Many plans require step therapy through Avastin or a biosimilar before approving brand Eylea or Lucentis, and require OCT documentation of fluid to continue approvals.

Operationally, the PA cadence has to match the injection cadence. A patient on monthly injections has 12 PAs per eye per year, many of which have to renew every 3-6 months. Flexbone runs the PA renewal calendar off the injection schedule, submits the next authorization before the current one expires, and handles the drug-change PAs when the retinal specialist switches agents.

ENT: tonsillectomy, sinus surgery, tympanostomy, cochlear

Tonsillectomy and adenoidectomy (42820 T&A under 12, 42821 T&A over 12, 42830 adenoidectomy) are pediatric PA workhorses. Payers want documented recurrent tonsillitis (usually 7 episodes in one year or 5 per year for 2 years per Paradise criteria), sleep-disordered breathing documentation, or biopsy-level concern for malignancy. Tympanostomy tube insertion (69433, 69436) for otitis media requires documented episode frequency and audiogram.

Endoscopic sinus surgery (31254-31298) is the highest-documentation ENT PA. Payers want CT sinus findings, failed medical therapy (antibiotics, nasal steroids, saline irrigation over 3-4 weeks for acute, 12 weeks for chronic), and documented symptom burden. Balloon sinuplasty (31295-31298) is a separate and narrower PA category that some plans still treat as investigational.

Oral and maxillofacial surgery

Oral surgery PA is unusual because it crosses medical and dental policies. Impacted third molar extraction (D7240 dental, 41899 unlisted medical, sometimes 21030 excision of benign lesion of mandible) is billed to medical when impacted below bone or when there is pathology, and to dental otherwise. Orthognathic surgery (21193, 21196, 21198, 21199) is almost always medical-plan PA with photographic documentation, cephalometric analysis, orthodontic treatment documentation, and a justification of functional vs cosmetic. TMJ surgery (21010 arthrotomy, 29800 arthroscopy) is medical-plan with imaging, conservative therapy documentation, and often a specialist consult.

Tumor, cyst, and biopsy work (41850-41870 bone grafts, 41805-41830 alveoloplasty and removal of lesion) depends on the pathology and location. Full mouth reconstruction post-trauma crosses into medical for the trauma portion and dental for the restorative portion. Flexbone runs dual submission to medical and dental payers in parallel when the clinical work crosses the line.

Audiology and cochlear implants

Cochlear implant PA (69930 for the implant, 92601-92604 for programming) is a high-packet PA requiring audiogram, speech discrimination scores under the plan threshold (commonly 40-60 percent), failed hearing aid trial, medical clearance, and candidacy evaluation from a cochlear implant center. Bone-anchored hearing aids (BAHA, 69714) require similar documentation with a different audiologic profile.

Hearing aids themselves are commonly patient-pay and not PA-relevant for traditional Medicare, but many MA plans and Medicaid programs include hearing-aid benefits with PA requirements. Tympanoplasty (69620, 69631) and stapedectomy (69660) require audiogram and imaging.

Payer-specific rules for eye, ENT, and oral

Ophthalmology PA largely stays with the plan's pharmacy benefit manager for intravitreal drugs (OptumRx, CVS Caremark, Express Scripts) even when the injection is administered medically. Retina specialists run dual PA: the medical PA for 67028 and the drug PA through the PBM. ENT PA typically stays with the medical plan directly, not delegated to eviCore or Carelon in most plans, though some BCBS plans use a delegate for sinus surgery specifically. Oral surgery routes to medical or dental depending on the specific procedure.

How Flexbone handles eye, ENT, and oral PA

The three sub-specialties share one architectural pattern: high PA volume, low per-case variance, recurring renewals. Flexbone runs them as a PA factory with schedule-driven submission, calendar-driven renewal for intravitreal and TMJ, and dual-rail submission for oral surgery when medical and dental both apply.
