Postdysenteric arthropathy, left hand

This code signifies inflammatory joint disease affecting the left hand that develops as a reactive sequela to a prior dysenteric infection. It is a form of reactive arthritis where the immune system, triggered by the gastrointestinal infection, mistakenly attacks the synovial lining of the joints.

Apply this code when documentation explicitly states a diagnosis of postdysenteric arthropathy localized to the left hand. This typically occurs after an episode of bacterial dysentery (e.g., Shigellosis, Salmonellosis) and presents with joint pain, swelling, and stiffness in the specified anatomical site.

• Ensure the documentation clearly links the arthropathy to a preceding dysenteric infection.
• Verify the specific joint involvement is documented as the "left hand" to support this laterality.
• Do not confuse with other forms of reactive arthritis or infectious arthritis where the pathogen is directly present in the joint.
