Unsp open wound of l idx fngr w/o damage to nail, sequela

This code signifies a past open wound on the left index finger that did not involve the nail structure. It indicates that the patient is now experiencing a residual condition or complication directly resulting from that previous injury. Examples of sequelae include scarring, chronic pain, or functional impairment.

Apply this code when documenting a current condition that is a late effect of an open wound to the left index finger, where the original injury did not damage the nail. This is appropriate for follow-up encounters addressing long-term consequences after the initial wound has healed.

• Always use a seventh character of 'S' for sequela when the current encounter addresses a complication or residual effect of a healed injury.
• Ensure documentation clearly links the current condition to the previous open wound of the left index finger.
• Do not use this code for the initial treatment of the acute open wound; that would require an 'A' or 'D' seventh character.
