Excludes1 — never code together — inherited from I80

The conditions below can never be reported together with I80.25 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 I80.25. I80.25 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
