Unsp injury of axillary or brachial vein, unsp side, subs

This code signifies an unspecified injury to either the axillary or brachial vein, located in the armpit or upper arm respectively, during a subsequent encounter for care. The exact nature of the injury (e.g., laceration, contusion, thrombosis) is not specified, nor is the laterality of the injury.

This code is appropriate when a patient presents for follow-up care, such as wound checks, medication adjustments, or physical therapy, related to an axillary or brachial vein injury where the specific type of injury is not documented. It is used when the initial injury has already been treated and the patient is in the healing or recovery phase.

• Only use this code for subsequent encounters; an initial encounter would require a different seventh character.
• Avoid this code if the specific type of vein injury (e.g., laceration, puncture) is known and documented.
• Ensure documentation clearly indicates an unspecified injury and a subsequent encounter.
