ICD-10 Code for Neuralgia
Also indexed as (acute)
The ICD-10-CM code for neuralgia is M79.2 — Neuralgia and neuritis, unspecified. This is the code the Alphabetic Index gives for neuralgia with no further qualifier, valid for FY2027 (October 1, 2026 – September 30, 2027).
M79.2 is billable but unspecified. If the documentation names a type, site or cause, one of the more specific codes below is likely expected.
Which neuralgia code should you use?
The Alphabetic Index lists 27 codes under Neuralgia, neuralgic. Which one applies depends on the qualifier documented in the record — the type, site, cause, or associated condition. Find the qualifier below, then verify the code in the Tabular List before using it.
