ICD-10 Code M06.20 – Rheumatoid bursitis, unspecified site (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M06.20 – Rheumatoid bursitis, unspecified site
What it is
M06.20 identifies bursitis caused by rheumatoid arthritis when the affected bursa is not specified. It tells you the bursitis is part of a rheumatoid disease process, but the site is not documented.
Clinical signs
Clinical features vary; refer to documentation. Typical bursitis findings include localized swelling, tenderness, and pain over a bursa, with evidence that the inflammation is related to rheumatoid arthritis.
When to use this code
Use this code when the record clearly links bursitis to rheumatoid arthritis and no anatomic site is named. It is appropriate in outpatient, inpatient, or specialist notes that document rheumatoid bursitis without further detail. If the site is identified, code the specific location instead.
Do not use for
Do not use it for nonspecific bursitis without a rheumatoid cause, or when the bursitis is traumatic, infectious, or due to another condition. Check documentation if the site or cause is unclear.
Coding tip
Confirm both the rheumatoid etiology and the absence of a documented site before assigning M06.20.
