Injury of blood vessels at shoulder and upper arm level (S45) ICD-10-CM

The S45 code range covers injury of blood vessels at shoulder and upper arm level with 241 ICD-10-CM diagnosis codes. 162 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.

Code Also

A "code also" note instructs that two codes may be required to fully describe a condition, but this note does not provide sequencing direction.

Type 2 Excludes

A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

7th Character Note

Certain ICD-10-CM categories have applicable 7th characters. The applicable 7th character is required for all codes within the category, or as the notes in the Tabular List instruct. The 7th character must always be the 7th character in the data field. If a code that requires a 7th character is not 6 characters, a placeholder X must be used to fill in the empty characters.

7th Character

Indicates that a seventh character is to be assigned to codes in a subcategory.

About the S45 Code Range

The ICD-10 codes in the S45 section are used to classify injuries to blood vessels located at the shoulder and upper arm level. These codes cover a range of injuries affecting arteries, veins, and superficial veins including lacerations, unspecified injuries, and other specific damage types.

This section specifically includes detailed codes for injuries to the axillary artery (such as S45.001A for unspecified right side axillary artery injury during initial encounter), brachial artery, and veins like the axillary or brachial veins. Some codes address injuries by side (right, left, or unspecified) and further specify encounter stages—initial, subsequent, or sequela. For example, S45.111A indicates a laceration of the right brachial artery at initial treatment, while S45.219D refers to a laceration of an unspecified side axillary or brachial vein during a subsequent encounter. Synonyms such as "injury of right axillary artery" and "laceration of brachial artery" help clarify medical documentation for coders seeking the precise ICD-10 codes for blood vessel injuries at shoulder and upper arm level. This range facilitates accurate coding of vascular trauma allowing for clear differentiation of injury type, location, and treatment phase.

Questions About This Page

How many billable codes are in the S45 range?

Of the 241 codes in this range, 162 are billable and valid for claim submission from October 1, 2025 through September 30, 2026. Category header codes group them but cannot be reported on claims.

What does the S45 range classify?

The range classifies injury of blood vessels at shoulder and upper arm level. Each code links to its own reference page with billing status, MS-DRG grouping, coding notes, and clinical information.
