In simple words: This code describes an injury to the structures that help straighten your right middle finger at the wrist/hand area.It's used when you're seeing the doctor again for this injury, and the type of injury (like a tear or sprain) isn't specified in your medical records.
Unspecified injury of the extensor muscle, fascia, and/or tendon of the right middle finger at the wrist and hand level. This code applies to a subsequent encounter for the injury, and the nature of the injury is not documented.
Example 1: A patient initially presented with pain and swelling in their right middle finger after a fall. They were diagnosed with a wrist injury. On a follow-up visit, the physician uses S66.302D as the patient continues to experience pain, but the specific nature of the injury remains unspecified., A patient was previously treated for a sports injury to their right middle finger. They return for a follow-up appointment to monitor their healing progress, and the provider documents S66.302D as the specific extensor tendon injury is not specified in the initial record., A patient injured their hand in a work accident. On a subsequent encounter, they continue to experience limited range of motion and discomfort in their right middle finger, but the nature of the tendon/muscle/fascia injury remains unclear. The provider uses S66.302D.
Documentation should include the location of the injury (right middle finger at wrist and/or hand level), the laterality (right), the fact that this is a subsequent encounter, and that the specific nature of the injury to the extensor muscle, fascia, or tendon is unspecified.
