G52Disorders of other cranial nerves

G52 is the ICD-10-CM diagnosis code for disorders of other cranial nerves. It belongs to block G50-G59 (nerve, nerve root and plexus disorders) and chapter 6 (diseases of the nervous system). It is a header code, so it can't be reported by itself; one of its 7 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: G52.0 (nerve), G52.1 (nerve), G52.2 (nerve), G52.3 (nerve), G52.7 (nerves), G52.8 (nerves) and G52.9 (unspecified).

The conditions in its Excludes2 note aren't part of G52, but may be coded alongside it if the patient has both: disorders of acoustic [8th] nerve (H93.3), disorders of optic [2nd] nerve (H46, H47.0) and paralytic strabismus due to nerve palsy (H49.0-H49.2).

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