Other secondary gout, unspecified hand

This code signifies a form of gout that develops as a consequence of another underlying medical condition or medication, affecting an unspecified hand. Unlike primary gout, which arises from metabolic defects, secondary gout is an acquired hyperuricemia leading to urate crystal deposition.

This code is appropriate when documentation specifies secondary gout affecting the hand, but the specific hand (right or left) is not recorded. It should be used when the etiology is clearly secondary, such as due to renal insufficiency, myeloproliferative disorders, or diuretic use, and the affected joint is in the hand.

• Ensure documentation explicitly states "secondary gout" and specifies involvement of the hand.
• Avoid using this code if the laterality (right or left hand) is documented; instead, choose the more specific M10.441 or M10.442.
• Always code the underlying condition causing the secondary gout first, followed by this code.
