Other streptococcal arthritis, left shoulder

This diagnosis code signifies an inflammatory joint condition affecting the left shoulder, specifically caused by a streptococcal bacterial infection. It represents a form of septic arthritis where streptococcus is identified as the causative organism, leading to pain, swelling, and restricted movement in the shoulder joint.

Apply this code when documentation clearly indicates a diagnosis of streptococcal arthritis localized to the left shoulder. This typically follows positive joint fluid cultures or other laboratory evidence confirming streptococcal etiology in a patient presenting with acute left shoulder arthralgia and inflammation.

• Ensure the documentation specifies "streptococcal" as the causative agent and "left shoulder" as the affected joint.
• Distinguish from other bacterial arthritides or non-infectious inflammatory arthropathies.
• Consider sequencing with codes for the underlying streptococcal infection if applicable and still active.
