W16.41XD — Fall into unspecified water causing drowning and submersion, subsequent encounter
W16.41XD is a billable, specific ICD-10-CM code for fall into unspecified water causing drowning and submersion, subsequent encounter. It is valid for submission on a claim.
7th character "D" — subsequent encounter
The appropriate 7th character is to be added to each code from category W16
- A
- initial encounter
- D
- subsequent encounter
- S
- sequela
Excludes1 inherited from the categories above W16.41XD
These are not written on W16.41XD, but they bind it: a note on a category applies to every code beneath it. Billing W16.41XD with anything listed here is a denial.
Excludes2 inherited from the categories above W16.41XD
Also inherited, and the opposite of Excludes1: these conditions are not part of W16.41XD, but a patient can have both, so you may code both.
Other codes that can never be billed with W16.41XD
These codes carry an Excludes1 note pointing at W16.41XD. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading W16.41XD alone.
Risk adjustment
W16.41XD 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
W16.41XD has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
