Idiopathic chronic gout, left wrist, without tophus (tophi)

This code signifies a diagnosis of chronic gout where the underlying cause is unknown (idiopathic), specifically affecting the left wrist joint. It indicates the absence of tophi, which are deposits of uric acid crystals that can form under the skin or in joints in advanced gout.

Apply this code when documentation confirms a diagnosis of chronic idiopathic gout localized to the left wrist, and explicitly states that no tophi are present. This would typically be supported by physician notes detailing chronic joint pain, swelling, and tenderness in the left wrist, along with laboratory findings consistent with gout, and imaging studies if performed.

• Ensure documentation clearly specifies "idiopathic" and "chronic" to differentiate from acute or secondary gout.
• Verify the affected joint is the "left wrist" and confirm the absence of "tophi" to ensure specificity.
• Consider sequencing this code after any codes for underlying conditions if the gout is secondary, though this code specifies idiopathic.
