ICD-10 code for adrenal calcification

The ICD-10-CM code for adrenal calcification is E27.49 (Other adrenocortical insufficiency). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on E27.49.

Within E27.4, choose E27.49 (Other adrenocortical insufficiency) only when documentation doesn't support a more specific option: unspecified adrenocortical insufficiency (E27.40).

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.
