Other streptococcal arthritis, right wrist

This code signifies an inflammatory condition of the right wrist joint caused by a streptococcal bacterial infection, excluding specific forms like post-infectious or reactive arthritis. The infection leads to acute arthritis, characterized by pain, swelling, and limited range of motion in the affected joint.

Apply this code when documentation clearly indicates a diagnosis of streptococcal arthritis affecting the right wrist. This typically occurs following a streptococcal infection elsewhere in the body, with subsequent hematogenous spread to the joint. Supporting documentation should include positive streptococcal cultures from synovial fluid or blood, or strong clinical evidence of streptococcal etiology.

• Ensure laterality is precisely documented; this code is specific to the right wrist.
• Distinguish from other forms of infectious arthritis (e.g., staphylococcal, gonococcal) and non-infectious inflammatory arthropathies.
• Code any underlying streptococcal infection (e.g., pharyngitis, cellulitis) as a primary diagnosis, if applicable, following sequencing guidelines.
