Lacerat extn musc/fasc/tend l idx fngr at forarm lv, sequela

This code describes a laceration affecting the extensor muscle, fascia, and tendon of the left index finger, with the injury site located at the forearm level. It specifically indicates that this is a sequela, meaning it represents a late effect or complication of an initial injury, rather than an acute event. The depth of the laceration involves all three specified tissue layers.

This code is appropriate for documenting follow-up care, complications, or chronic conditions resulting from a previous laceration to the extensor structures of the left index finger. It should be used when the original injury occurred at the forearm level and the patient is now presenting with issues directly related to that past trauma, such as scar tissue, chronic pain, or functional impairment.

• Ensure the documentation clearly specifies the left index finger and that the injury occurred at the forearm level.
• Verify that the laceration involves the extensor muscle, fascia, AND tendon.
• Confirm that the encounter is for a sequela, not an acute injury, and link it to the appropriate external cause code if applicable.
