Other streptococcal arthritis, right hip

This code signifies an inflammatory joint condition of the right hip caused by a streptococcal bacterial infection, but not classified as rheumatic fever or post-infection. It indicates an acute or chronic arthropathy resulting from the presence of Streptococcus in the joint space or a reactive process to a streptococcal infection elsewhere in the body.

Assign this code when documentation specifies streptococcal arthritis affecting the right hip, excluding cases directly linked to rheumatic fever. Supporting documentation should include a confirmed diagnosis of streptococcal infection (e.g., positive culture, elevated ASO titers) and clinical evidence of arthritis localized to the right hip joint.

• Differentiate from rheumatic arthritis (M00.0-) and other bacterial arthritides (M00.8-).
• Ensure laterality (right hip) is clearly documented; do not default if not specified.
• Code the underlying streptococcal infection (e.g., A49.1 for streptococcal infection, unspecified) as an additional diagnosis if still active and relevant.
