Postdysenteric arthropathy, right shoulder

This code signifies an inflammatory joint condition affecting the right shoulder that develops as a reactive sequela to a previous 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 joint.

Apply this code when documentation clearly indicates a diagnosis of reactive arthropathy of the right shoulder following a confirmed or suspected dysenteric episode. The patient typically presents with acute, sterile arthritis symptoms in the right shoulder, often weeks or months after the initial gastrointestinal infection has resolved.

• Ensure documentation specifies the laterality (right shoulder) and the post-dysenteric etiology.
• Do not confuse with other forms of reactive arthritis (e.g., post-streptococcal) or septic arthritis.
• Sequence this code as the primary diagnosis if it is the reason for the encounter, or as a secondary diagnosis if managing other conditions concurrently.
