Unsp open wound of l little finger w damage to nail, sequela

This code signifies a healed or residual effect from an open wound to the left little finger, specifically involving damage to the nail. The original injury's nature is not specified, but its lasting impact on the nail is the key clinical feature.

Use this code when documenting follow-up care for a patient who previously sustained an open wound to their left little finger with nail damage, and the current encounter addresses a sequela of that injury. This applies to conditions like nail deformities, chronic pain, or functional limitations directly attributable to the past wound.

• Ensure documentation clearly links the current condition to a previous open wound of the left little finger with nail involvement.
• Always use this "S" seventh character for sequela, indicating a late effect of the original injury.
• Code any current, active complications or specific nail pathologies in addition to this sequela code, if applicable.
