Inj cutan sensory nerve at forarm lv, left arm, sequela

This code indicates a long-term or late effect of an injury to a cutaneous sensory nerve in the left forearm. This type of injury affects the nerves responsible for sensation in the skin, potentially leading to persistent numbness, tingling, or altered sensation in the affected area. The "sequela" designation signifies that the initial injury has resolved, but its lasting effects are still present.

Use this code for patients presenting with residual sensory deficits, such as chronic paresthesia, dysesthesia, or anesthesia, in the left forearm, where the underlying cause was a past injury to a cutaneous sensory nerve. This applies when the acute phase of the injury has passed, and the current encounter addresses the ongoing consequences.

• Always assign a sequela code as the primary diagnosis when the residual condition is the reason for the encounter.
• Ensure documentation clearly specifies the left forearm and the cutaneous sensory nerve involvement.
• Consider additional codes for specific symptoms (e.g., pain, numbness) if they are also being treated.
