ICD-10-CM Code C74.00
Malignant neoplasm of cortex of unspecified adrenal gland
Billable Code
Billable codes are sufficient justification for admission to an acute care hospital when used a principal diagnosis.C74.00 is a billable ICD code used to specify a diagnosis of malignant neoplasm of cortex of unspecified adrenal gland. A 'billable code' is detailed enough to be used to specify a medical diagnosis.
The ICD code C740 is used to code Adrenocortical carcinoma
Adrenocortical carcinoma, also adrenal cortical carcinoma (ACC) and adrenal cortex cancer, is an aggressive cancer originating in the cortex (steroid hormone-producing tissue) of the adrenal gland. Adrenocortical carcinoma is a rare tumor, with incidence of 1–2 per million population annually. Adrenocortical carcinoma has a bimodal distribution by age, with cases clustering in children under 5, and in adults 30–40 years old. Adrenocortical carcinoma is remarkable for the many hormonal syndromes which can occur in patients with steroid hormone-producing ("functional") tumors, including Cushing's syndrome, Conn syndrome, virilization, and feminization. Adrenocortical carcinoma has often invaded nearby tissues or metastasized to distant organs at the time of diagnosis, and the overall 5-year survival rate is only 20–35%. The widely used angiotensin-II-responsive steroid-producing cell line H295R was originally isolated from a tumor diagnosed as adrenocortical carcinoma.

Equivalent ICD-9 Code GENERAL EQUIVALENCE MAPPINGS (GEM)
This is the official approximate match mapping between ICD9 and ICD10, as provided by the General Equivalency mapping crosswalk. This means that while there is no exact mapping between this ICD10 code C74.00 and a single ICD9 code, 194.0 is an approximate match for comparison and conversion purposes.
