E75.1

E75.1 — Other and unspecified gangliosidosis

Non-billable headerICD-10-CM

Excludes1 inherited from the categories above E75.1

These are not written on E75.1, but they bind it: a note on a category applies to every code beneath it. Billing E75.1 with anything listed here is a denial.

Written on E75 — Disorders of sphingolipid metabolism and other lipid storage disorders

mucolipidosis, types I-III (E77.0-E77.1)
Refsum's disease (G60.1)

Other codes that can never be billed with E75.1

These codes carry an Excludes1 note pointing at E75.1. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading E75.1 alone.

Risk adjustment

E75.1 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.

E75.1 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
