Laceration of unsp blood vessel at forarm lv, left arm, subs

This code signifies a laceration of an unspecified blood vessel located in the left forearm. The injury has been previously treated, and the patient is now presenting for follow-up care, such as wound checks, dressing changes, or medication adjustments, during the healing phase.

Use this code for a patient presenting for subsequent care of a left forearm blood vessel laceration where the specific vessel (e.g., radial artery, ulnar vein) was not documented or identified. This applies to encounters occurring after the initial treatment of the acute injury.

• Ensure documentation clearly indicates the encounter is for follow-up care of a previously treated injury, not the initial presentation.
• If the specific blood vessel is identified, a more precise code from the S55 category should be used instead.
• Always verify laterality (left arm) is accurately documented to support this code.
