ICD-10 Code M05.151 – Rheumatoid lung disease with rheumatoid arthritis of right hip (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M05.151 – Rheumatoid lung disease with rheumatoid arthritis of right hip
What it is
This code identifies rheumatoid arthritis affecting the right hip in a patient who also has rheumatoid lung disease. Use it when the record links both conditions to the same rheumatoid disease process.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include inflammatory joint pain, stiffness, reduced hip motion, and documented pulmonary involvement related to rheumatoid disease.
When to use this code
Use this code when the provider documents rheumatoid arthritis of the right hip and rheumatoid lung disease together. It applies when the lung condition is part of the rheumatoid diagnosis, not a separate unrelated pulmonary disorder.
Choose this code only if the right hip is specifically identified. If the site is unspecified, bilateral, or another joint is documented, code the record exactly as written.
Do not use for
Do not use this code for rheumatoid arthritis without lung involvement, or for lung disease not documented as rheumatoid. Check documentation if the hip side is not stated.
Coding tip
Verify that the provider explicitly connects the lung disease and right hip arthritis to rheumatoid arthritis before assigning M05.151.
