ICD-10 Code for Parasomnia
The ICD-10-CM code for parasomnia is G47.50 — Parasomnia, unspecified. This is the code the Alphabetic Index gives for parasomnia with no further qualifier, valid for FY2027 (October 1, 2026 – September 30, 2027).
G47.50 is billable but unspecified. If the documentation names a type, site or cause, one of the more specific codes below is likely expected.
