About coding disease or syndrome addison's
The ICD-10-CM code for disease or syndrome addison's is E27.1 (Primary 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 E27.1.
Within E27 (other disorders of adrenal gland), E27.1 is specifically for primary adrenocortical insufficiency. Related codes cover other adrenocortical overactivity (E27.0), Addisonian crisis (E27.2), drug-induced adrenocortical insufficiency (E27.3), other and unspecified adrenocortical insufficiency (E27.4), Adrenomedullary hyperfunction (E27.5), other specified disorders of adrenal gland (E27.8) and disorder of adrenal gland, unspecified (E27.9).
Don't report E27.1 together with the conditions in its Excludes1 note: Addison only phenotype adrenoleukodystrophy (E71.528), amyloidosis (E85.-), tuberculous Addison's disease (A18.7) and Waterhouse-Friderichsen syndrome (A39.1).
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.
