Other reactive arthropathies, unspecified shoulder

This code signifies an inflammatory joint condition affecting an unspecified shoulder, triggered by an infection elsewhere in the body, but without a specific causative organism or detailed arthropathy type documented. It represents a post-infectious arthritis where the immune system reacts to a prior infection, leading to joint inflammation.

Use this code when documentation indicates reactive arthropathy of the shoulder, but the specific type (e.g., Reiter's, post-dysenteric) is not specified, nor is the laterality of the shoulder. This code is appropriate when the physician explicitly diagnoses "reactive arthropathy, shoulder, unspecified" or similar, and no further details are available.

• Avoid using this code if a more specific type of reactive arthropathy (e.g., M02.3- for Reiter's disease) or a specific shoulder (e.g., M02.811 for right shoulder) is documented.
• Always query the provider for laterality (right, left, bilateral) if not specified, as more specific codes exist.
• Ensure documentation supports the "reactive" nature of the arthropathy, distinguishing it from other forms of inflammatory or degenerative arthritis.
