Cigna modified MM 0019 covering anti-reflux procedures and POEM, effective September 26, 2025. Here's what billing teams need to know.
Cigna Healthcare updated its Minimally Invasive Anti-Reflux Procedures and Peroral Endoscopic Myotomy (POEM) coverage policy under MM 0019 Cigna system. The change maintains POEM (CPT 43497) as medically necessary for achalasia while keeping the majority of anti-reflux procedures — including CPT 43210, 43236, 43257, and 43284 — firmly in experimental/investigational status. If your practice bills for any esophageal or GERD-related procedures to Cigna patients, this policy update sets the lines you need to know before September 26, 2025.

Cigna Anti-Reflux and POEM Coverage Criteria and Medical Necessity Requirements 2025
The Cigna anti-reflux and POEM coverage policy draws a hard line between two categories: POEM-related procedures for esophageal motility disorders, and endoscopic anti-reflux procedures for GERD.
POEM for Achalasia — Covered
CPT 43497 (lower esophageal myotomy, transoral — POEM) meets Cigna's medical necessity standard for the treatment of achalasia. This is the clearest covered indication in the policy. If your team bills 43497 for achalasia patients, you're on solid ground — but document the diagnosis explicitly. Cigna's medical necessity criteria live and die on what's in the chart.
CPT 43999 (unlisted procedure, stomach) is also considered medically necessary, but specifically for refractory gastroparesis. This is a narrow indication. Don't assume 43999 gets the same treatment across all stomach procedures — the coverage applies to refractory gastroparesis specifically, and you'll want prior authorization locked in before billing.
GERD Anti-Reflux Procedures — Experimental Across the Board
For GERD, Cigna's position is unambiguous: the minimally invasive and endoscopic anti-reflux procedures are experimental and investigational. That designation applies to CPT 43210 (EGD with esophagogastric fundoplasty), CPT 43236 (EGD with directed submucosal injection), CPT 43257 (EGD with delivery of thermal energy to the lower esophageal sphincter — this is the Stretta procedure), and CPT 43284 (laparoscopic sphincter augmentation — the LINX procedure).
These are not borderline calls. These procedures have been the subject of ongoing coverage debate for years, and Cigna isn't moving off experimental status with this update.
Prior Authorization
Given the experimental designation on the majority of these codes, prior authorization is effectively a non-starter for the GERD anti-reflux procedures — you won't get it approved. For CPT 43497 and CPT 43999, confirm prior auth requirements with your Cigna rep directly, since individual plan contracts can vary. Never assume reimbursement is automatic even for medically necessary codes.
Cigna Anti-Reflux Procedure Exclusions and Non-Covered Indications
Six of the ten codes in this policy carry an experimental/investigational/unproven designation. That's not a gray area — it means Cigna won't pay, and billing these codes for Cigna patients without clear documentation of a different clinical scenario is a fast path to claim denial.
CPT 43210 covers EGD with esophagogastric fundoplasty (partial or complete). This is the transoral incisionless fundoplication (TIF) procedure. Cigna considers it experimental when used for GERD treatment.
CPT 43236 covers EGD with directed submucosal injection. Used in some anti-reflux protocols, it carries the same experimental designation here.
CPT 43257 is the Stretta procedure — radiofrequency energy delivered to the lower esophageal sphincter muscle. Cigna has held this position on Stretta for years. Nothing in this update changes it.
CPT 43284 is the LINX magnetic sphincter augmentation procedure. Also experimental. This one surprises some billing teams because LINX has FDA approval, but FDA clearance and payer coverage are different conversations.
CPT 43289 (unlisted laparoscopy procedure, esophagus), CPT 43499 (unlisted procedure, esophagus), and CPT 43659 (unlisted laparoscopy procedure, stomach) are all experimental in this context. Unlisted codes require special handling even when the underlying procedure is covered — when the underlying procedure is experimental, you're dealing with a double barrier.
The real issue with the experimental designations on unlisted codes is that practices sometimes use 43289, 43499, or 43659 to bill emerging or modified anti-reflux techniques. Under this coverage policy, that approach doesn't work for Cigna patients.
Coverage Indications at a Glance
| Indication | Status | Relevant Codes | Notes |
|---|---|---|---|
| Esophageal achalasia (POEM) | Covered / Medically Necessary | CPT 43497 | Document achalasia diagnosis clearly; confirm prior auth requirements per plan |
| Refractory gastroparesis | Covered / Medically Necessary | CPT 43999 | Narrow indication — "refractory" must be documented; confirm prior auth |
| GERD — transoral fundoplasty (TIF) | Experimental/Investigational/Unproven | CPT 43210 | Not covered; expect claim denial |
| GERD — submucosal injection | Experimental/Investigational/Unproven | CPT 43236 | Not covered |
| GERD — Stretta (radiofrequency) | Experimental/Investigational/Unproven | CPT 43257 | Not covered; long-standing Cigna position |
| GERD — LINX (sphincter augmentation) | Experimental/Investigational/Unproven | CPT 43284 | Not covered despite FDA approval |
| Unlisted esophageal/laparoscopic procedures for GERD | Experimental/Investigational/Unproven | CPT 43289, 43499, 43659 | Not covered in anti-reflux context |
| Unlisted stomach procedures (non-gastroparesis) | Experimental/Investigational/Unproven | CPT 43999 (non-refractory gastroparesis) | Only refractory gastroparesis qualifies |
Cigna Anti-Reflux and POEM Billing Guidelines and Action Items 2025
| # | Action Item |
|---|---|
| 1 | Audit your charge capture for all ten codes before September 26, 2025. Pull claims from the past 12 months for CPT 43210, 43236, 43257, 43284, 43289, 43289, 43497, 43499, 43659, and 43999. Identify which are going to Cigna patients. Flag anything that doesn't align with the covered indications. |
| 2 | Verify the achalasia diagnosis is explicit in every chart where you bill 43497. Medical necessity for POEM under this policy is diagnosis-specific. A chart that references dysphagia or motility disorder without confirming achalasia is a claim denial waiting to happen. Your clinical documentation needs to match Cigna's criteria exactly. |
| 3 | Stop billing CPT 43210, 43257, and 43284 to Cigna without a prior authorization or appeal pathway. These are the most common anti-reflux procedures — TIF, Stretta, and LINX — and all three are experimental under this policy. If a physician is still performing these on Cigna patients expecting coverage, that conversation needs to happen now, before the effective date. |
| 4 | Treat CPT 43999 carefully. This unlisted stomach code is medically necessary only for refractory gastroparesis. If your practice uses 43999 for other stomach procedures, segment those claims by indication. Billing 43999 for a non-refractory gastroparesis indication to Cigna will result in denial. |
| 5 | Confirm prior authorization requirements for CPT 43497 and 43999 on a plan-by-plan basis. Cigna's employer-sponsored plans can have different prior auth rules than their commercial individual plans. Don't assume a blanket rule applies. Call to verify before scheduling the procedure. |
| 6 | Brief your clinical team on the LINX and Stretta position. Physicians sometimes assume FDA-approved devices carry automatic payer coverage. CPT 43284 (LINX) is the clearest example of that gap. If a surgeon is booking LINX or Stretta cases on Cigna patients, revenue cycle needs to be in that conversation before the case is scheduled. |
| 7 | If you use unlisted codes for novel anti-reflux techniques, talk to your compliance officer now. The experimental designation on CPT 43289, 43499, and 43659 under this coverage policy limits your options. Some practices use unlisted codes to bill newer variations of established anti-reflux procedures. Under MM 0019, that approach faces a structural barrier with Cigna. Your compliance officer and billing consultant need to weigh in before the effective date of September 26, 2025. |
