Oth rheumatoid arthritis with rheumatoid factor of left hip

This code signifies a diagnosis of rheumatoid arthritis that is seropositive for rheumatoid factor, affecting the left hip joint. It indicates a specific type of inflammatory arthritis where the body's immune system attacks its own tissues, with the presence of rheumatoid factor in the blood, and the left hip is the primary site of manifestation.

Use this code when documentation confirms a diagnosis of rheumatoid arthritis with positive rheumatoid factor and the left hip is the affected joint. This code is appropriate for patients presenting with pain, swelling, and stiffness in the left hip, along with laboratory evidence of rheumatoid factor.

• Ensure documentation explicitly states "left hip" and "rheumatoid factor positive" to support this specific code.
• Distinguish from seronegative rheumatoid arthritis (M06.0-) or other specified rheumatoid arthritis (M05.8-) affecting different joints.
• Consider sequencing with codes for associated complications or manifestations of rheumatoid arthritis if present.
