M32.14Glomerular disease in systemic lupus erythematosus

M32.14 is the ICD-10-CM diagnosis code for glomerular disease in systemic lupus erythematosus. It belongs to category M32 (systemic lupus erythematosus (SLE)), block M30-M36 (systemic connective tissue disorders) 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 M32.1 (systemic lupus erythematosus with organ or system involvement), M32.14 is specifically for glomerular disease in systemic lupus erythematosus. Related codes cover systemic lupus erythematosus, organ or system involvement unspecified (M32.10), endocarditis in systemic lupus erythematosus (M32.11), pericarditis in systemic lupus erythematosus (M32.12), lung involvement in systemic lupus erythematosus (M32.13), tubulo-interstitial nephropathy in systemic lupus erythematosus (M32.15) and other organ or system involvement in systemic lupus erythematosus (M32.19).

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 545 (Connective Tissue Disorders with MCC, relative weight 2.3892), DRG 546 (Connective Tissue Disorders with CC, relative weight 1.1745) and DRG 547 (Connective Tissue Disorders without CC/MCC, relative weight 0.7526), in MDC 08 (Diseases and Disorders of the Musculoskeletal System and Connective Tissue), 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 583.81 (nephritis and nephropathy, not specified as acute or chronic, in diseases classified elsewhere) and 710.0 (systemic lupus erythematosus).
