T75.1 — Unspecified effects of drowning and nonfatal submersion

Non-billable headerICD-10-CM

The appropriate 7th character is to be added to each code from category T75

A: initial encounter
D: subsequent encounter
S: sequela

Risk adjustment

T75.1 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.
