Other secondary gout, left shoulder

This code signifies an inflammatory arthritis of the left shoulder joint caused by the deposition of uric acid crystals, where the gout is a consequence of another underlying medical condition or medication. It indicates that the patient is experiencing a gout attack in the left shoulder, not as a primary condition, but secondary to another disease process.

Apply this code when documentation clearly states "secondary gout" affecting the left shoulder. This typically occurs in patients with conditions like chronic kidney disease, myeloproliferative disorders, or those on certain diuretics or chemotherapy, where these underlying factors contribute to hyperuricemia and subsequent gout. Ensure the medical record specifies the laterality of the affected joint.

• Differentiate from primary gout (M10.0-) and lead-induced gout (M10.1-).
• Always code the underlying condition causing the secondary gout first.
• Verify documentation specifies "left shoulder" and "secondary" to avoid miscoding.
