Postimmunization arthropathy, unspecified hip

This code describes inflammation and pain in an unspecified hip joint that develops as a reaction to a recent immunization. It indicates a non-infectious arthritic condition occurring after vaccination, without specifying the exact type of arthropathy.

Use this code when documentation clearly links hip joint pain and inflammation to a recent immunization, and the specific type of arthropathy is not further defined. This code is appropriate when the laterality of the affected hip is not specified in the medical record.

• Always sequence the immunization encounter code (Z23.-) or the adverse effect of vaccine code (T50.B1-) as the primary diagnosis, if applicable, followed by this code.
• If the specific type of postimmunization arthropathy (e.g., reactive, seronegative) or the laterality of the hip is documented, use a more specific code from the M02.2- series.
• Ensure documentation explicitly states the connection between the immunization and the hip arthropathy; otherwise, a general arthropathy code may be more appropriate.
