V90 ICD-10-CM Code: Drowning and submersion due to accident to watercraft

V90 is the ICD-10-CM diagnosis code for drowning and submersion due to accident to watercraft. V90 sits in the ICD-10-CM chapter for external causes of morbidity (v00-y99), within the section covering water transport accidents (v90-v94).

Header codes like V90 cannot be reported on claims directly, they organize child codes that share clinical context but the actual diagnosis must be coded to the highest level of specificity supported by the documentation. Coders should look at V90's child codes and select the one that matches the patient's documented presentation, since payers reject header codes submitted as the primary diagnosis. For risk adjustment workflows, header codes never contribute to a Medicare Advantage member's RAF score on their own; only billable child codes that happen to map to a payment HCC affect risk-adjusted plan payments.
