ICD-10 Code M05.141 – Rheumatoid Lung Disease with Rheumatoid Arthritis of Right Hand (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M05.141 – Rheumatoid lung disease with rheumatoid arthritis of right hand
What it is
This code identifies rheumatoid arthritis affecting the right hand, with associated rheumatoid lung disease. Use it when the record clearly links the lung involvement to rheumatoid arthritis.
Clinical signs
Findings may include inflammatory joint symptoms in the right hand plus documented pulmonary involvement related to rheumatoid disease. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents rheumatoid arthritis in the right hand and also states rheumatoid lung disease. It is appropriate when both conditions are linked in the assessment or problem list. Check documentation if laterality or the lung manifestation is unclear.
Do not use for
Do not use it for rheumatoid arthritis without lung disease, or for lung disease not documented as rheumatoid in origin. Check documentation if the right hand is not specified.
Coding tip
Assign the code only when the record supports both the right-hand site and the rheumatoid lung manifestation.
