ICD-10 Code for Lymphoma
Also indexed as (of) (malignant)
The ICD-10-CM code for lymphoma is C85.90 — Non-Hodgkin lymphoma, unspecified, unspecified site. This is the code the Alphabetic Index gives for lymphoma with no further qualifier, valid for FY2027 (October 1, 2026 – September 30, 2027).
BillableUnspecified
C85.90 is billable but unspecified. If the documentation names a type, site or cause, one of the more specific codes below is likely expected.
Which lymphoma code should you use?
The Alphabetic Index lists 52 codes under Lymphoma. 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.
