ICD-10 Code for Myeloma
Also indexed as (multiple)
The ICD-10-CM code for myeloma is C90.0 — Multiple myeloma. This is the code the Alphabetic Index gives for myeloma with no further qualifier, valid for FY2027 (October 1, 2026 – September 30, 2027).
C90.0 cannot be submitted on a claim. It is a header code, so a more specific code from the list below is required.
Which myeloma code should you use?
The Alphabetic Index lists 3 codes under Myeloma. 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.
By type
Myeloma monostotic
| plasma cell | C90.0 | Multiple myeloma | not billable |
Codes under C90.0
Index terms and codes are reproduced from the official ICD-10-CM FY2027 release. The Alphabetic Index is a finding aid — a code must always be verified in the Tabular List before it is reported. Data sources
