Where does V91.39 sit in the tabular list?

External causes of morbidity (V00-Y99), in the block Water transport accidents (V90-V94).

What cannot be coded together with V91.39?

V91.39 carries Excludes1 notes, which means the conditions they list can never be coded together with it on the same encounter. Some are written on the categories above V91.39 (V91) and apply to it just the same.

V91.39 — Hit or struck by falling object due to accident to unspecified watercraft

Non-billable headerICD-10-CM

V91.39 is a non-billable header ICD-10-CM code for hit or struck by falling object due to accident to unspecified watercraft. It cannot be billed on its own: choose one of the more specific child codes below. This code also requires a 7th character before it is complete.

Excludes1 inherited from the categories above V91.39

These are not written on V91.39, but they bind it: a note on a category applies to every code beneath it. Billing V91.39 with anything listed here is a denial.

Written on V91 — Other injury due to accident to watercraft

civilian water transport accident involving military watercraft (V94.81-)
military watercraft accident in military or war operations (Y36, Y37.-)

Excludes2 inherited from the categories above V91.39

Also inherited, and the opposite of Excludes1: these conditions are not part of V91.39, but a patient can have both, so you may code both.

Written on V91.3 — Hit or struck by falling object due to accident to watercraft

drowning or submersion due to fall or jumping from damaged watercraft (V90.2-, V90.3-)

Written on V91 — Other injury due to accident to watercraft

drowning and submersion due to accident to watercraft (V90.-)

Other codes that can never be billed with V91.39

These codes carry an Excludes1 note pointing at V91.39. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading V91.39 alone.

V93Other injury due to accident on board watercraft, without accident to watercraft

Risk adjustment

V91.39 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.

How V91.39 is indexed

Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to V91.39.
