- 314Other Circulatory System Diagnoses with MCCmedical
- 315Other Circulatory System Diagnoses with CCmedical

Excludes1 — never code together — inherited from B50-B64
The conditions below can never be reported together with B57.0 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
