Staphylococcal arthritis, left hand

This code signifies an inflammatory condition of the left hand joints caused by a Staphylococcus bacterial infection. It indicates the presence of pus and inflammation within the synovial membrane and joint space, leading to pain, swelling, and restricted movement in the affected hand.

Apply this code when documentation clearly states a diagnosis of staphylococcal arthritis specifically affecting the left hand. This typically occurs following a bacterial culture confirming Staphylococcus as the causative agent in a patient presenting with acute joint inflammation. Ensure the laterality of the hand is explicitly documented.

• Confirm the infectious agent is Staphylococcus; other bacterial arthritides have different codes.
• Verify the affected joint is in the left hand; codes exist for other sites and laterality.
• Sequence this code first if it is the primary reason for the encounter.
