H91 vs H93.01
H91 (Other and unspecified hearing loss) compared with H93.01 (Transient ischemic deafness), from the official CMS tabular data. Do not report these codes together: the official tabular list marks them Excludes1.
Can these codes be reported together?
No — do not report together. H91 carries an Excludes1 note covering H93.01: “transient ischemic deafness (H93.01-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
