Non-Billable/Non-Specific Code

O22 should not be used for reimbursement purposes as there are multiple codes below it that contain a greater level of detail.

This is the American ICD-10-CM version of O22 - other international versions of ICD-10 O22 may differ.

Type 1 Excludes

Type 1 Excludes Help

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 O22. 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.

A type 2 excludes note represents "not included here". A type 2 excludes note indicates that the condition excluded is not part of the condition it is excluded from but a patient may have both conditions at the same time. When a type 2 excludes note appears under a code it is acceptable to use both the code (O22) and the excluded code together.
