Idiopathic gout, unspecified hip

This code signifies a diagnosis of gout where the underlying cause is unknown (idiopathic), specifically affecting the hip joint. Gout is an inflammatory arthritis characterized by the deposition of monosodium urate crystals in joints, leading to sudden, severe attacks of pain, redness, and tenderness.

Use this code when documentation confirms a diagnosis of idiopathic gout localized to the hip, without further specification of laterality (left or right). This code is appropriate when the provider has ruled out secondary causes of gout and the hip is the affected joint.

• Ensure the documentation explicitly states "idiopathic gout" and specifies the "hip" as the affected joint.
• Avoid using this code if the laterality (left or right hip) is documented; instead, use the more specific codes M10.051 or M10.052.
• Do not use this code for gout due to lead poisoning, drug-induced gout, or gout secondary to renal impairment; these have specific codes within the M1A category.
