About coding Hypercortisonism
The ICD-10-CM code for Hypercortisonism is E24.2 (Drug-induced Cushing's syndrome).
Within E24 (Cushing's syndrome), E24.2 is specifically for drug-induced Cushing's syndrome. Related codes cover Pituitary-dependent Cushing's disease (E24.0), Nelson's syndrome (E24.1), ectopic ACTH syndrome (E24.3), alcohol-induced pseudo-Cushing's syndrome (E24.4), other Cushing's syndrome (E24.8) and unspecified (E24.9).
Use an additional code for adverse effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5).
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.
