About M10.321

M10.321 is the ICD-10-CM diagnosis code for gout due to renal impairment, right elbow. It belongs to category M10 (gout), block M05-M14 (inflammatory polyarthropathies) and chapter 13 (diseases of the musculoskeletal system and connective tissue). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within M10.32 (gout due to renal impairment, elbow), M10.321 is specifically for gout due to renal impairment, right elbow. Related codes cover left elbow (M10.322) and unspecified elbow (M10.329).

Use an additional code to identify: Autonomic neuropathy in diseases classified elsewhere (G99.0), Calculus of urinary tract in diseases classified elsewhere (N22), Cardiomyopathy in diseases classified elsewhere (I43), Disorders of external ear in diseases classified elsewhere (H61.1-, H62.8-), Disorders of iris and ciliary body in diseases classified elsewhere (H22) and 1 more.

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 698 (Other Kidney and Urinary Tract Diagnoses with MCC, relative weight 1.6398), DRG 699 (Other Kidney and Urinary Tract Diagnoses with CC, relative weight 1.0003) and DRG 700 (Other Kidney and Urinary Tract Diagnoses without CC/MCC, relative weight 0.6741), in MDC 11 (Diseases and Disorders of the Kidney and Urinary Tract), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 274.10 (gouty nephropathy, unspecified).
