About coding syndrome or disease cushing's
The ICD-10-CM code for syndrome or disease cushing's is E24.9 (Cushing's syndrome, unspecified). The official index lists 4 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on E24.9.
Within E24, choose E24.9 (unspecified) only when documentation doesn't support a more specific option: Pituitary-dependent Cushing's disease (E24.0), Nelson's syndrome (E24.1), drug-induced Cushing's syndrome (E24.2), ectopic ACTH syndrome (E24.3), alcohol-induced pseudo-Cushing's syndrome (E24.4) and other Cushing's syndrome (E24.8).
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 643 (Endocrine Disorders with MCC, relative weight 1.6139), DRG 644 (Endocrine Disorders with CC, relative weight 1.0044) and DRG 645 (Endocrine Disorders without CC/MCC, relative weight 0.7459), 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.
