ICD-10 Code for Kyphosis
Also indexed as (acquired)
The ICD-10-CM code for kyphosis is M40.209 — Unspecified kyphosis, site unspecified. This is the code the Alphabetic Index gives for kyphosis with no further qualifier, valid for FY2027 (October 1, 2026 – September 30, 2027).
M40.209 is billable but unspecified. If the documentation names a type, site or cause, one of the more specific codes below is likely expected.
