ICD-10 Code for Myofibromatosis
The ICD-10-CM code for myofibromatosis is D48.19 — Other specified neoplasm of uncertain behavior of connective and other soft tissue. This is the code the Alphabetic Index gives for myofibromatosis with no further qualifier, valid for FY2027 (October 1, 2026 – September 30, 2027).
D48.19 is billable but unspecified. If the documentation names a type, site or cause, one of the more specific codes below is likely expected.
