Rheumatoid heart disease w rheumatoid arthritis of unsp hip

This code signifies a systemic autoimmune disorder characterized by chronic inflammation affecting the heart and an unspecified hip joint. It indicates the presence of both rheumatoid arthritis and cardiac involvement, such as pericarditis, myocarditis, or valvular disease, stemming from the same underlying rheumatoid process.

Assign this code when documentation clearly states a diagnosis of rheumatoid heart disease in a patient also suffering from rheumatoid arthritis affecting an unspecified hip. This code is appropriate when the specific hip (left or right) is not documented by the provider.

• Ensure documentation explicitly links the cardiac condition to the rheumatoid arthritis.
• Do not use this code if the hip involvement is due to osteoarthritis or another non-rheumatoid etiology.
• If the specific hip is documented (e.g., left or right), a more specific code from the M05.35- subcategory should be used.
