Other secondary gout, unspecified site

This code signifies a form of gout that develops as a consequence of another underlying medical condition, rather than primary metabolic dysfunction, but the specific anatomical location of the gouty arthritis is not documented. It indicates the presence of uric acid crystal deposition and inflammation in a joint, secondary to a known cause, without specifying which joint is affected.

Utilize this code when the medical record clearly states "secondary gout" or "gout secondary to [another condition]" but lacks documentation of the specific joint(s) involved. This is appropriate when the physician has identified a secondary cause for the gout, such as renal insufficiency, myeloproliferative disorders, or certain medications, but the affected site remains unspecified.

• Ensure documentation explicitly states "secondary gout" and that no specific joint is identified.
• Always code the underlying condition causing the secondary gout first, followed by this code.
• If a specific site of secondary gout is documented, use the more precise M10.4- subcategory codes (e.g., M10.411 for right shoulder).
