Independence Blue Cross updated MA08.125d to remove specific lung cancer ICD-10 diagnosis codes (C33, C34.xx series) and now requires providers to report the most appropriate diagnosis code supporting medical necessity criteria. Coverage for Lurbinectedin (Zepzelca®) for small cell lung cancer treatment remains substantively unchanged, but diagnosis code reporting is now more flexible and less prescriptive. This change affects all SCLC claims billed under this policy effective June 1, 2026.
