S65.510 Laceration of blood vessel of right index finger

ICD-10-CM Code S65.510: Laceration of blood vessel of right index finger

ICD-10-CM code S65.510 identifies a laceration of a blood vessel of the right index finger and is classified as an injury or poisoning concept. The code is active and has no narrower concepts. It is distinct from initial encounter codes like S65.511A, which appear in payer billing articles. 1 3 5

Plain-language overview

Code S65.510 identifies a laceration of a blood vessel in the right index finger, and the terminology record classifies this concept as an injury or poisoning. 1

What this code represents

The S65.510 terminology record is active for the 2026 ICD-10-CM version, and this specific code has no narrower child concepts within the terminology. 1

The parent concept for S65.510 is S65.51, which is the laceration of a blood vessel of another and unspecified finger in the ICD-10-CM hierarchy. [S1] 1

Coding details

A billing and coding article lists S65.511A for a right index finger blood vessel laceration during an initial encounter, distinguishing it from the S65.510 base code. 3

The S65.510 code identifies a right index finger blood vessel laceration, whereas S65.512A identifies a left index finger blood vessel laceration during an initial encounter. 3

Clinical context

A compromised blood supply in a finger might cause downstream complications for nerve healing and function, and each finger receives its blood supply from two proper digital arteries. 2

Documentation considerations

Following a traumatic finger injury, verifying blood supply and sufficient perfusion is necessary, and a clinical study used clinical assessments and circulatory imaging for this verification. 2

What the sources add

The terminology record defines S65.510 as an active injury concept, while the billing article lists related initial encounter codes for right and left index finger blood vessel lacerations. 1 3

A clinical study found no major differences in functional outcomes based on one-vessel or two-vessel blood supply following unilateral traumatic finger injuries. 2
