Excludes1 — never code together — inherited from G90

The conditions below can never be reported together with G90.A on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • dysfunction of the autonomic nervous system due to alcohol (G31.2)

Excludes2 — not included here — inherited from Chapter 6

The conditions below are not part of G90.A, but a patient may have both at the same time. When documentation supports it, G90.A and the excluded code may both be reported.

  • certain conditions originating in the perinatal period (P04-P96)
  • certain infectious and parasitic diseases (A00-B99)
  • complications of pregnancy, childbirth and the puerperium (O00-O9A)
  • congenital malformations, deformations, and chromosomal abnormalities (Q00-Q99)
  • endocrine, nutritional and metabolic diseases (E00-E88)
  • injury, poisoning and certain other consequences of external causes (S00-T88)
  • neoplasms (C00-D49)
  • symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (R00-R94)
