S55.891A
ICD-10-CMOther specified injury of other blood vessels at forearm level, right arm, initial encounter
This code signifies an injury to a named, but not specifically categorized, blood vessel in the right forearm. This could involve arteries or veins other than the major named vessels (e.g., radial, ulnar, brachial) that are more specifically coded. The "initial encounter" designation indicates the patient is receiving active treatment for this fresh injury.
Apply this code when documentation specifies an injury to a blood vessel in the right forearm that isn't the radial, ulnar, or brachial artery/vein, and the patient is presenting for the first time for this specific injury. Examples include trauma to smaller, unnamed arteries or veins, or a specified but less common vessel. This code is appropriate for initial evaluations and treatments of such injuries.
