Other codes that can never be billed with A15

These codes carry an Excludes1 note pointing at A15. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading A15 alone.

  • A15.4Tuberculosis of intrathoracic lymph nodes
  • A15.6Tuberculous pleurisy
  • J03.8Acute tonsillitis due to other specified organisms
  • J47Bronchiectasis

  • J61Pneumoconiosis due to asbestos and other mineral fibers
  • J62Pneumoconiosis due to dust containing silica
  • J63Pneumoconiosis due to other inorganic dusts

A15 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Code to one of these instead A15

7 child codes. Green means billable.
