About H93.3X

H93.3X is the ICD-10-CM diagnosis code for disorders of acoustic nerve. It belongs to category H93 (other disorders of ear, not elsewhere classified), block H90-H94 (other disorders of ear) and chapter 8 (diseases of the ear and mastoid process). It is a header code, so it can't be reported by itself; one of its 4 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: H93.3X1 (nerve), H93.3X2 (nerve), H93.3X3 (nerves) and H93.3X9 (nerve).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
