Summary
Independence Blue Cross has reissued policy 11.03.17 on Peroral Endoscopic Myotomy (POEM) procedures, maintaining its existing coverage position: POEM is covered only for achalasia type III (spastic) in patients age 18+ with Eckardt symptom score >6 and confirmed esophageal manometry. All other POEM variants (G-POEM, D-POEM, Z-POEM) remain experimental/investigational and not covered. This is a policy reaffirmation with no substantive coverage changes from the prior version.
Action Required
No immediate action required. This is a policy reaffirmation (last reviewed 07/09/2025) with no coverage changes. Billing team should verify that claims for CPT 43497 (standard POEM) are only submitted when all three medical necessity criteria are met: (1) patient age ≥18, (2) achalasia type III diagnosis via esophageal manometry, and (3) Eckardt symptom score >6. Ensure claims using CPT 43999 or 43499 for G-POEM, D-POEM, or Z-POEM variants are denied as experimental/investigational. Confirm ICD-10 diagnosis code K22.0 (achalasia of cardia) is present on medically necessary claims. No system updates or workflow changes are required at this time.
