Other secondary chronic gout, unspecified elbow, with tophus

This code signifies a chronic form of gout that is secondary to another underlying condition, affecting an unspecified elbow joint. The distinguishing feature is the presence of tophi, which are deposits of uric acid crystals that form visible lumps under the skin or within joints. This indicates a long-standing and often severe manifestation of gout.

Use this code when documentation clearly indicates chronic gout in the elbow, specifically noting that it is secondary to another disease process. The presence of tophi must be explicitly documented, and the affected elbow should not be specified as right or left. This code is appropriate when the provider has not identified the specific underlying cause of the secondary gout.

• Ensure documentation specifies "secondary" gout and the presence of "tophi" in the elbow.
• Avoid using this code if the laterality (right or left elbow) is documented; instead, use the more specific M1A.4211 or M1A.4221.
• Always code the underlying condition causing the secondary gout first, followed by this code.
