How is H46.1 listed in the Alphabetic Index?
These are the routes through the Alphabetic Index that lead to H46.1. They show the wording a clinician may have documented, which often differs from the Tabular description.

Excludes1 — never code together
The conditions below can never be reported together with H46.1 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
