Excludes1 inherited from the categories above Y37.250A
These are not written on Y37.250A, but they bind it: a note on a category applies to every code beneath it. Billing Y37.250A with anything listed here is a denial.
Written on Y37.2 — Military operations involving other explosions and fragments
Written on Y37 — Military operations
- military aircraft involved in aircraft accident with civilian aircraft (V97.81-)
- military vehicles involved in transport accident with civilian vehicle (V09.01, V09.21, V19.81, V29.818, V39.81, V49.81, V59.81, V69.81, V79.81)
- military watercraft involved in water transport accident with civilian watercraft (V94.81-)
- war operations (Y36.-)
Other codes that can never be billed with Y37.250A
These codes carry an Excludes1 note pointing at Y37.250A. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading Y37.250A alone.
Risk adjustment
Y37.250A 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
Y37.250A has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
