Contusion of left ring finger w/o damage to nail, sequela

This code signifies a bruise to the left ring finger that does not involve injury to the nail or nail bed. It specifically indicates a long-term effect or complication arising from an initial contusion.

Apply this code when documenting a current condition that is a residual effect of a past contusion to the left ring finger, where the nail was not damaged. This is appropriate for follow-up encounters addressing persistent symptoms or complications from the original injury.

• Always assign an external cause code (V00-Y99) in conjunction with this code to describe the circumstances of the original injury.
• Ensure documentation clearly states the contusion is of the left ring finger and that the nail was not involved.
• The "S" seventh character indicates a sequela, meaning the patient is being seen for a late effect of the initial injury.
