Non-Billable/Non-Specific Code

I34 should not be used for reimbursement purposes as there are multiple codes below it that contain a greater level of detail.
The 2023 edition of ICD-10-CM I34 became effective on October 1, 2022.
This is the American ICD-10-CM version of I34 - other international versions of ICD-10 I34 may differ.

Type 1 Excludes

A type 1 excludes note is a pure excludes. It means "not coded here". A type 1 excludes note indicates that the code excluded should never be used at the same time as I34. A type 1 excludes note is for used for when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
