Excludes1 — never code together — inherited from Z15

The conditions below can never be reported together with Z15.8 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • chromosomal anomalies (Q90-Q99)

Use additional code — inherited from Z15

Report an additional code alongside Z15.8 to fully describe the condition. Z15.8 is sequenced first.
