Pulmonary — codes without an RBCS family
13 CPT®/HCPCS codes, ranked by est. all-Medicare services — scaled from national Medicare Part B fee-for-service volume. Open any code for the full market view — ranked physician groups, geography, and 12-year trend.
CMS's RBCS classification leaves these codes at the subcategory level — no family is assigned. We list them; we don't invent a family.
