E72.0 — Disorders of amino-acid transport
E72.0 is a non-billable header ICD-10-CM code for disorders of amino-acid transport. 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.
- disorders of tryptophan metabolism (E70.5)
Excludes1 inherited from the categories above E72.0
These are not written on E72.0, but they bind it: a note on a category applies to every code beneath it. Billing E72.0 with anything listed here is a denial.
Other codes that can never be billed with E72.0
These codes carry an Excludes1 note pointing at E72.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading E72.0 alone.
Risk adjustment
E72.0 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.
Code history
E72.0 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
Code to one of these instead E72.0

- Endocrine, nutritional and metabolic diseases (E00-E89), in the block Metabolic disorders (E70-E88).
- What cannot be coded together with E72.0?
