Action Required
Verify current applicability: Aetna CPB 0744 classifies bronchial thermoplasty (CPT 31660, 31661) as experimental, investigational, or unproven for asthma and chronic lower respiratory diseases. The policy was reviewed on 2026-10-21 but no change effective date is stated in the source. Billing team should confirm whether this non-coverage stance remains in effect for Aetna commercial plans and ensure that claims for CPT 31660 and 31661 with ICD-10 codes J41.0–J47.9 and J67.0–J67.9 are either denied or require prior authorization denial before submission. Update billing system edits to flag these code combinations and communicate to providers that this procedure is not covered under Aetna plans.
