Cigna modified MM 0335 covering otoplasty and external ear reconstruction, effective September 26, 2025. Here's what billing teams need to do.
Cigna Healthcare updated its coverage policy for otoplasty and external ear reconstruction under MM 0335 in the Cigna system. This policy draws a sharp line between cosmetic and medically necessary procedures—and where that line falls has direct consequences for your reimbursement. The seven CPT codes in scope include 69300, 69310, 69320, 20910, 20912, 21230, and 21235. Get these sorted before September 26, 2025.

Cigna Otoplasty and Ear Reconstruction Coverage Criteria and Medical Necessity Requirements 2025
The Cigna otoplasty and external ear reconstruction coverage policy under MM 0335 splits into two distinct categories. Understand which bucket your procedure falls into before you bill.
CPT 69300 — Cosmetic, full stop. Cigna classifies otoplasty for protruding ears as cosmetic and not medically necessary. That's the procedure described by CPT 69300, "Otoplasty, protruding ear, with or without size reduction." There is no path to medical necessity coverage for this code under MM 0335. If your team bills 69300 to Cigna expecting reimbursement, expect a claim denial.
CPT 69310 and 69320 — Covered when criteria are met. Reconstruction of the external auditory canal (meatoplasty) under CPT 69310 and reconstruction for congenital atresia under CPT 69320 are considered medically necessary when the applicable criteria are satisfied. The policy language ties coverage to specific clinical indications—stenosis due to injury or infection for 69310, congenital atresia for 69320. Document those clinical justifications thoroughly in the chart before submitting.
Cartilage graft codes — Conditionally covered. CPT codes 20910, 20912, 21230, and 21235 are considered medically necessary when submitted with a medically necessary primary procedure. These are graft codes—they don't stand alone. If the primary ear reconstruction procedure doesn't meet medical necessity, the graft codes fall with it. If the primary procedure is covered, the graft codes follow—but only if that primary procedure is documented and supported.
Prior authorization requirements are common on reconstructive ear procedures across commercial plans. Check Cigna's prior authorization list for CPT 69310, 69320, and associated graft codes before scheduling. A missing prior auth on a reconstructive procedure is a preventable claim denial, and MM 0335 gives Cigna clear grounds to deny if the documentation doesn't hold up.
Cigna Otoplasty Exclusions and Non-Covered Indications
MM 0335 is explicit: otoplasty for protruding ears is cosmetic. Cigna does not cover CPT 69300 under any medical necessity argument. This isn't a gray area.
The real risk here is upcoding or misclassification. Some practices attempt to frame a protruding-ear correction as a reconstructive procedure to get coverage. Cigna's coverage policy addresses this directly by carving out CPT 69300 as cosmetic. That means diagnosis coding and operative notes need to match the actual procedure performed.
If a patient wants otoplasty for aesthetic reasons, have that financial conversation before surgery—not after you've submitted a claim. Collecting on CPT 69300 means collecting from the patient, not from Cigna.
Coverage Indications at a Glance
| Indication | Status | Relevant Codes | Notes |
|---|---|---|---|
| Otoplasty for protruding ears | Not Covered (Cosmetic) | 69300 | No path to medical necessity under MM 0335 |
| Reconstruction of external auditory canal — stenosis due to injury or infection | Covered (criteria must be met) | 69310 | Document clinical indication explicitly; verify prior auth |
| Reconstruction of external auditory canal — congenital atresia | Covered (criteria must be met) | 69320 | Congenital atresia must be documented; verify prior auth |
| Cartilage graft — costochondral | Covered (when primary procedure is medically necessary) | 20910 | Dependent on covered primary procedure |
| Cartilage graft — nasal septum | Covered (when primary procedure is medically necessary) | 20912 | Dependent on covered primary procedure |
| Rib cartilage graft — autogenous, to face, chin, nose, or ear | Covered (when primary procedure is medically necessary) | 21230 | Dependent on covered primary procedure |
| Ear cartilage graft — autogenous, to nose or ear | Covered (when primary procedure is medically necessary) | 21235 | Dependent on covered primary procedure |
Cigna Otoplasty and Ear Reconstruction Billing Guidelines and Action Items 2025
The effective date of September 26, 2025 is your line in the sand. Here's what your billing team needs to do before then.
| # | Action Item |
|---|---|
| 1 | Flag all pending claims with CPT 69300. Pull any outstanding Cigna claims that include 69300. These will not be covered under MM 0335. If they're not yet submitted, have the financial counseling conversation with the patient now. If they've already been submitted, prepare for denial and shift to patient responsibility collections. |
| 2 | Audit your charge capture for CPT 69310 and 69320. Make sure your team is linking the correct clinical indications to these codes. For 69310, the chart must reflect stenosis due to injury or infection. For 69320, congenital atresia must be documented. Vague documentation won't hold up on audit. |
| 3 | Check prior authorization requirements before scheduling. Cigna's otoplasty and ear reconstruction billing process often requires prior auth on reconstructive procedures. Confirm current prior authorization requirements for CPT 69310 and 69320 with Cigna directly. Don't assume last year's process still applies after the September 26, 2025 effective date. |
| 4 | Never submit cartilage graft codes without a supported primary procedure. CPT codes 20910, 20912, 21230, and 21235 are medically necessary only when submitted alongside a covered primary procedure. Build a charge capture rule or billing guideline that flags these codes if the primary procedure is missing or classified as cosmetic. |
| 5 | Update your ABN process for CPT 69300. If your practice performs otoplasty for protruding ears and you have Cigna patients, your advance beneficiary notice—or equivalent patient financial responsibility notice—needs to be in place before the procedure. Waiting until post-claim denial creates patient relations problems and delays collections. |
| 6 | Train your surgical schedulers on the cosmetic vs. reconstructive distinction. The front end of the revenue cycle is where this goes wrong most often. Schedulers need to know that 69300 is a self-pay procedure for Cigna patients, while 69310 and 69320 require prior auth and documented clinical criteria. If your schedulers don't know this distinction, your denials will tell you. |
| 7 | Review your operative note templates for ear reconstruction cases. The medical necessity criteria for 69310 and 69320 need to appear in the operative note—not just the diagnosis code on the claim. Work with your clinical documentation team to make sure the standard note template captures the cause of stenosis or the congenital atresia diagnosis in a way that maps directly to the Cigna medical necessity standard. |
If your practice has a high volume of ear reconstruction cases billed to Cigna, loop in your compliance officer before September 26, 2025. The distinction between cosmetic and reconstructive procedures is exactly the kind of line that triggers audits when claims patterns shift.
