E78.2 vs M67
E78.2 (Mixed hyperlipidemia) compared with M67 (Other disorders of synovium and tendon), from the official CMS tabular data. Do not report these codes together: the official tabular list marks them Excludes1.
Can these codes be reported together?
No — do not report together. M67 carries an Excludes1 note covering E78.2: “xanthomatosis localized to tendons (E78.2)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
