No. E25 is a non-billable header code. Code to a higher level of specificity using one of its child codes.

Where does E25 sit in the tabular list?

Endocrine, nutritional and metabolic diseases (E00-E89), in the block Disorders of other endocrine glands (E20-E35).

E25 carries an Excludes1 note, which means the conditions it lists can never be coded together with it on the same encounter.

E25

E25 — Adrenogenital disorders

Non-billable headerICD-10-CM

E25 is a non-billable header ICD-10-CM code for adrenogenital disorders. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

indeterminate sex and pseudohermaphroditism (Q56)
chromosomal abnormalities (Q90-Q99)

Includes

Conditions this code covers.

adrenogenital syndromes, virilizing or feminizing, whether acquired or due to adrenal hyperplasia consequent on inborn enzyme defects in hormone synthesis
Female adrenal pseudohermaphroditism
Female heterosexual precocious pseudopuberty
Male isosexual precocious pseudopuberty
Male macrogenitosomia praecox
Male sexual precocity with adrenal hyperplasia
Male virilization (female)

Other codes that can never be billed with E25

These codes carry an Excludes1 note pointing at E25. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading E25 alone.

Q56Indeterminate sex and pseudohermaphroditism
Q89.1Congenital malformations of adrenal gland
E24Cushing's syndrome
E30.1Precocious puberty

Risk adjustment

E25 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Code to one of these instead E25

3 child codes. Green means billable.
