Excludes1 — never code together — inherited from B40

The conditions below can never be reported together with B40.8 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • Brazilian blastomycosis (B41.-)
  • keloidal blastomycosis (B48.0)

Use additional code — inherited from Chapter 1

Report an additional code alongside B40.8 to fully describe the condition. B40.8 is sequenced first.

  • code to identify resistance to antimicrobial drugs (Z16.-)
