About E88.10

E88.10 is the ICD-10-CM diagnosis code for lipodystrophy, unspecified. It belongs to category E88 (other and unspecified metabolic disorders), block E70-E88 (metabolic disorders) and chapter 4 (endocrine, nutritional and metabolic diseases). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within E88.1, choose E88.10 (Lipodystrophy, unspecified) only when documentation doesn't support a more specific option: partial lipodystrophy (E88.11), generalized lipodystrophy (E88.12), localized lipodystrophy (E88.13), HIV-associated lipodystrophy (E88.14) and other lipodystrophy, not elsewhere classified (E88.19).

Use an additional code for: codes for associated conditions.

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 642 (Inborn and Other Disorders of Metabolism, relative weight 1.3219), in MDC 10 (Endocrine, Nutritional and Metabolic Diseases and Disorders), 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 was added in FY2026, effective October 1, 2025.
