Chronic gout due to renal impairment, mult sites, w/o toph

This code signifies a persistent form of gout that arises as a direct consequence of impaired kidney function, affecting multiple joints throughout the body. It specifically indicates the absence of visible tophi, which are deposits of uric acid crystals. The underlying renal dysfunction leads to elevated uric acid levels, precipitating gout attacks.

Use this code for patients diagnosed with chronic gout where the etiology is clearly linked to renal impairment, and the gout manifests in more than one anatomical site. Documentation should explicitly state "chronic gout due to renal impairment" and confirm the absence of tophi, along with specifying multiple affected joints.

• Always sequence a code for the underlying chronic kidney disease (CKD) first, as it is the causal factor for the gout.
• Ensure documentation clearly distinguishes between acute and chronic gout; this code is for chronic presentations.
• Verify the absence of tophi; if tophi are present, a different M1A.39X_ code would be appropriate.
