Excludes1 — never code together — inherited from I80
The conditions below can never be reported together with I80.29 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 I80.29. I80.29 describes a manifestation and cannot be the principal or first-listed diagnosis.
