Unsp inj unsp blood vess at forarm lv, unsp arm, sequela

This code signifies a long-term complication or residual effect stemming from an unspecified injury to an unspecified blood vessel in the forearm. The original injury occurred on an unspecified arm, and the current encounter addresses a sequela, not the acute injury itself.

Apply this code when documenting a chronic or late-effect condition directly attributable to a past, ill-defined blood vessel injury in the forearm. This is appropriate for follow-up care or evaluation of persistent issues after the initial injury has healed.

• Only use this code for sequelae; never for the initial acute injury.
• Avoid this code if more specific information about the blood vessel, type of injury, or arm is available.
• Always sequence this code after the code(s) for the specific sequela being treated.
