Chronic gout due to renal impairment, unsp hip, with tophus

This diagnosis code signifies a persistent inflammatory arthritis affecting an unspecified hip joint, specifically caused by chronic kidney disease leading to elevated uric acid levels. The distinguishing feature is the presence of tophi, which are subcutaneous or intra-articular deposits of urate crystals.

Apply this code when documentation clearly indicates chronic gout as a sequela of renal impairment, with the hip joint being affected, and the presence of tophaceous deposits. This diagnosis requires a confirmed link between the patient's kidney dysfunction and their gout.

• Ensure documentation specifies "chronic" gout and explicitly links it to "renal impairment."
• Verify the presence of "tophus" or "tophi" in the clinical notes.
• Do not use this code if the laterality of the hip is specified; instead, select the appropriate laterality code.
