Other secondary gout, unspecified wrist

This code signifies a form of gout that develops as a consequence of another underlying medical condition or medication, specifically affecting an unspecified wrist joint. It indicates the presence of urate crystal deposition and inflammation in the wrist, but the primary cause is not idiopathic.

Apply this code when documentation clearly states "secondary gout" affecting the wrist, and the specific wrist (right or left) is not identified. This diagnosis is typically supported by clinical findings of gouty arthritis in the wrist, elevated serum uric acid levels, and the presence of a known secondary cause such as chronic kidney disease, diuretic use, or myeloproliferative disorders.

• Ensure documentation specifies "secondary gout" and not primary gout, which has different code assignments.
• If the laterality of the wrist is documented (right or left), use the more specific codes M10.431 or M10.432.
• Always code the underlying secondary condition first, followed by this code for the manifestation of secondary gout.
