Traumatic rupture of collateral ligament of unsp wrist, subs

This code signifies a traumatic tear of a collateral ligament in an unspecified wrist, indicating that the injury occurred due to an external force. The "subsequent encounter" designation means the patient is receiving routine care during the healing or recovery phase of this specific injury, not for the initial treatment.

Apply this code when documenting follow-up visits for a patient with a previously diagnosed traumatic collateral ligament rupture of the wrist, where the specific ligament (e.g., radial or ulnar) was not documented. This includes appointments for cast changes, physical therapy, medication management, or monitoring of healing progress after the initial treatment.

• Ensure documentation clearly states a traumatic cause and that this is not the initial treatment encounter.
• If the specific collateral ligament (radial or ulnar) is identified, a more specific code from the S63.31- category should be used.
• Always append the appropriate 7th character for subsequent encounters ("D").
