Other specified crystal arthropathies, right hip

This code signifies a diagnosis of an arthropathy of the right hip caused by the deposition of crystals other than those associated with gout (e.g., calcium pyrophosphate dihydrate, calcium hydroxyapatite). It indicates an inflammatory joint condition resulting from these crystal formations.

Use this code when documentation specifies crystal-induced arthritis affecting the right hip, and the crystal type is identified but is not uric acid (gout). This diagnosis is typically supported by synovial fluid analysis showing non-urate crystals, imaging findings, and clinical presentation of hip pain and inflammation.

• Ensure the documentation clearly specifies "right hip" and identifies the crystal type as "other specified" (i.e., not gout).
• Do not use this code for gouty arthropathy; instead, refer to codes in the M10 category.
• Consider sequencing this code with an external cause code if the crystal deposition is secondary to a specific medical condition or medication.
