ICD-10 Code for Neuritis
Also indexed as (rheumatoid)
The ICD-10-CM code for neuritis is M79.2 — Neuralgia and neuritis, unspecified. This is the code the Alphabetic Index gives for neuritis 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 neuritis code should you use?
The Alphabetic Index lists 42 codes under Neuritis. 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.
