ICD-10 code for Sacks-Libman disease

The ICD-10-CM code for Sacks-Libman disease is M32.11 (Endocarditis in systemic lupus erythematosus).

Within M32.1 (systemic lupus erythematosus with organ or system involvement), M32.11 is specifically for endocarditis in systemic lupus erythematosus. Related codes cover systemic lupus erythematosus, organ or system involvement unspecified (M32.10), pericarditis in systemic lupus erythematosus (M32.12), lung involvement in systemic lupus erythematosus (M32.13), glomerular disease in systemic lupus erythematosus (M32.14), tubulo-interstitial nephropathy in systemic lupus erythematosus (M32.15) and other organ or system involvement in systemic lupus erythematosus (M32.19).

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.

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.
