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

This code signifies a long-term complication or residual effect stemming from an unspecific injury to an unspecified blood vessel in the right forearm. The original injury is no longer acute, and the patient is experiencing ongoing issues related to the vascular damage.

Apply this code when documenting a chronic condition or sequela resulting from a past, ill-defined blood vessel injury in the right forearm. This would be appropriate for patients presenting with persistent symptoms like chronic pain, swelling, or functional impairment directly attributable to the old vascular trauma.

• Requires a seventh character 'S' to indicate sequela.
• Only use when the specific type of blood vessel and the exact nature of the injury are unknown or not documented.
• Always sequence after the code(s) for the specific sequela being treated.
