Non-Billable/Non-Specific Code

J66 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 J66 - other international versions of ICD-10 J66 may differ.

Type 2 Excludes

Type 2 Excludes Help

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 (J66) and the excluded code together.
