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

This code describes the long-term effects or complications resulting from a previous blunt force injury to the middle finger of the left hand. Specifically, it indicates that the nail itself was not damaged during the initial contusion, but the patient is now experiencing residual issues from that past injury.

This code is appropriate when a patient presents with ongoing symptoms such as pain, stiffness, or limited range of motion in the left middle finger, and these symptoms are directly attributed to a contusion that occurred in the past. It should be used when the initial injury has healed, but its lasting impact is still being addressed.

• Always assign this code as a secondary diagnosis, following the code for the current condition or symptom being treated.
• Ensure documentation clearly links the current symptoms to a past contusion of the left middle finger.
• Verify that the medical record explicitly states "without damage to nail" and that the injury is a sequela, not an acute event.
