ICD-10 code for adrenal gland cyst

The ICD-10-CM code for adrenal gland cyst is E27.8 (Other specified disorders of adrenal gland). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on E27.8.

Within E27, choose E27.8 (Other specified disorders of adrenal gland) only when documentation doesn't support a more specific option: other adrenocortical overactivity (E27.0), primary adrenocortical insufficiency (E27.1), Addisonian crisis (E27.2), drug-induced adrenocortical insufficiency (E27.3), other and unspecified adrenocortical insufficiency (E27.4), Adrenomedullary hyperfunction (E27.5) and disorder of adrenal gland, unspecified (E27.9).

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 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.
