ICD-10 Code M05.722 – Rheumatoid arthritis with rheumatoid factor of left elbow without organ or systems involvement (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M05.722 – Rheumatoid arthritis with rheumatoid factor of left elbow without organ or systems involvement
What it is
This code identifies rheumatoid arthritis affecting the left elbow in a patient who is rheumatoid factor positive and has no documented involvement of other organs or body systems.
Clinical signs
Typical findings include inflammatory joint pain, swelling, stiffness, and reduced range of motion in the left elbow. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record clearly states rheumatoid arthritis, rheumatoid factor positivity, and left elbow involvement. It also applies when documentation specifies no organ or system involvement beyond the joint.
If the note only says rheumatoid arthritis or does not identify the elbow side, check documentation before assigning this code. You need clear laterality and site specificity.
Do not use for
Do not use this code for rheumatoid arthritis without rheumatoid factor, unspecified elbow laterality, or disease with documented organ or systemic involvement. Check documentation.
Coding tip
Verify both rheumatoid factor status and left-sided elbow involvement in the same encounter note before coding.
