Excludes1 — never code together — inherited from I80

The conditions below can never be reported together with I80.8 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

Code first — inherited from I80

The underlying condition below must be sequenced before I80.8. I80.8 describes a manifestation and cannot be the principal or first-listed diagnosis.

  • , if applicable: phlebitis and thrombophlebitis complicating abortion, ectopic or molar pregnancy (O00-O07, O08.7)
  • phlebitis and thrombophlebitis complicating pregnancy, childbirth and the puerperium (O22.-, O87.-)

Excludes2 — not included here — inherited from Chapter 9

The conditions below are not part of I80.8, but a patient may have both at the same time. When documentation supports it, I80.8 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)

  • transient cerebral ischemic attacks and related syndromes (G45.-)
