Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Acid sphingomyelinase deficiency type A (ASMD type A)
- Infantile neurovisceral acid sphingomyelinase deficiency
Excludes1 inherited from the categories above E75.240
These are not written on E75.240, but they bind it: a note on a category applies to every code beneath it. Billing E75.240 with anything listed here is a denial.
Other codes that can never be billed with E75.240
These codes carry an Excludes1 note pointing at E75.240. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading E75.240 alone.
- R79Other abnormal findings of blood chemistry
Risk adjustment
E75.240 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
E75.240 is named in 13 Medicare coverage policies — 13 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
