S65.515 ICD-10-CM Code: Laceration of blood vessel of left ring finger

S65.515 is the ICD-10-CM diagnosis code for laceration of blood vessel of left ring finger. S65.515 sits in the ICD-10-CM chapter for injury, poisoning and certain other consequences of external causes (s00-t88), within the section covering injuries to the wrist, hand and fingers (s60-s69).

Header codes like S65.515 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 S65.515'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.
