Drug-induced chronic gout, unspecified hip, without tophus

This diagnosis code signifies a form of chronic gout that has been medically determined to be caused by a pharmaceutical agent, affecting an unspecified hip joint. It indicates the absence of visible or palpable urate crystal deposits (tophi) associated with this chronic condition. The patient experiences persistent inflammation and pain in the hip due to drug-induced uric acid accumulation.

Use this code when documentation clearly states chronic gout of the hip is drug-induced and no tophi are present. This typically applies to patients with a history of medication use (e.g., diuretics, aspirin) that elevates uric acid levels, leading to chronic gouty arthritis in the hip. Supporting documentation should include a physician's assessment linking the drug to the gout and specifying the affected joint.

• Ensure the documentation explicitly states "drug-induced" and "chronic" gout.
• Confirm the affected joint is the hip and that "without tophus" is specified or implied by the absence of documentation of tophi.
• Always code the adverse effect of the drug (T36-T50 with 5th or 6th character 5) as a secondary diagnosis to identify the specific medication causing the gout.
