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

This code signifies a long-term complication or late effect stemming from an injury to an axillary or brachial vein. The specific nature of the original injury and the affected side are not documented or are unknown. This diagnosis indicates that the patient is currently experiencing residual issues directly attributable to a past venous trauma in the upper arm or shoulder region.

Apply this code when a patient presents with a current condition (e.g., chronic pain, lymphedema, venous insufficiency, or scar tissue) that is a direct consequence of a previously sustained, but now healed, injury to an axillary or brachial vein. This is appropriate when the initial injury details are no longer available or were never specified, and the laterality is also unrecorded.

• Only use this code for sequelae; the original acute injury should have been coded previously.
• Ensure documentation clearly links the current condition to a past axillary or brachial vein injury.
• Avoid using this code if the laterality or specific vein injury type is known and can be coded with a more precise sequela code.
