Contusion of left ring finger with damage to nail, sequela

This code indicates a bruise on the left ring finger that has caused damage to the nail, and the current encounter is for the long-term effects or complications of that initial injury. This could include ongoing nail deformity, chronic pain, or other persistent issues stemming from the original contusion.

Apply this code when a patient presents for follow-up care related to a past contusion of the left ring finger with nail damage, and the current symptoms or conditions are a direct consequence of that prior injury. This is appropriate for encounters addressing residual problems that have stabilized but continue to impact the patient.

• Ensure documentation clearly links the current condition to the previous left ring finger contusion with nail damage.
• This "S" seventh character indicates a sequela, meaning the acute phase of the injury has passed.
• Do not use this code for the initial acute injury or for subsequent active treatment of the acute injury.
