M71.5 vs M76.4
M71.5 (Other bursitis, not elsewhere classified) compared with M76.4 (Tibial collateral bursitis [Pellegrini-Stieda]), 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. M71.5 carries an Excludes1 note covering M76.4: “enthesopathies (M76-M77)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
Yes, when both are documented. M71.5 carries an Excludes2 note covering M76.4: “bursitis of tibial collateral [Pellegrini-Stieda] (M76.4-)”
Excludes2 marks distinct conditions — both may be reported when both are documented.
