E25.0 — Congenital adrenogenital disorders associated with enzyme deficiency
E25.0 is a billable, specific ICD-10-CM code for congenital adrenogenital disorders associated with enzyme deficiency. It is valid for submission on a claim.
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Congenital adrenal hyperplasia
- 21-Hydroxylase deficiency
- Salt-losing congenital adrenal hyperplasia
Other codes that can never be billed with E25.0
These codes carry an Excludes1 note pointing at E25.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading E25.0 alone.
Risk adjustment
E25.0 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.
Medicare coverage
E25.0 is named in 6 Medicare coverage policies — 6 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.

- A56421Billing and Coding: CT of the Abdomen and Pelvis
- A56619Billing and Coding: Nerve Conduction Studies and Electromyography
- A57204Billing and Coding: MRI and CT Scans of the Head and Neck
How E25.0 is indexed
Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to E25.0.
