Inj extensor musc/fasc/tend unsp finger at forarm lv, init

This code signifies an injury to an extensor muscle, its surrounding fascia, or a tendon of an unspecified finger, where the injury is located at the forearm level. This indicates damage to the structures responsible for extending the fingers, occurring proximally to the hand itself. The "initial encounter" designation means this code is used for the first time a patient is seen for this specific injury.

Use this code when documentation clearly indicates an injury to an extensor structure (muscle, fascia, or tendon) affecting any finger, and the injury site is specified as being within the forearm. This would apply to acute traumatic events such as lacerations, strains, or ruptures impacting these structures at the forearm level.

• Ensure the documentation specifies an extensor structure and not a flexor.
• Verify the injury location is at the "forearm level" and not within the hand or wrist.
• Confirm that the encounter is the initial treatment for this specific injury.
