ICD-10 Code M06.029 – Rheumatoid arthritis without rheumatoid factor, unspecified elbow (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M06.029 – Rheumatoid arthritis without rheumatoid factor, unspecified elbow
What it is
This code identifies rheumatoid arthritis affecting an unspecified elbow when rheumatoid factor is not present. Use it for inflammatory arthritis documented in the elbow without a more specific laterality or site detail.
Clinical signs
Typical findings include joint pain, swelling, stiffness, and reduced range of motion in the elbow. Clinical features vary; refer to documentation for evidence of rheumatoid arthritis and seronegative status.
When to use this code
Use M06.029 when the provider documents rheumatoid arthritis without rheumatoid factor and does not specify right or left elbow. It also fits when the elbow is named as the affected joint but laterality is unavailable. If the record is unclear, check documentation before coding.
Do not use for
Do not use this code for rheumatoid arthritis with positive rheumatoid factor, or when the diagnosis is limited to another joint. Do not assign it if the elbow side is documented and a more specific code applies.
Coding tip
Confirm both the serologic status and elbow laterality in the note before selecting M06.029.
