Unspecified injury of neck, subsequent encounter

This code signifies an unspecified injury to the neck during a subsequent encounter for care. It indicates that the specific nature of the neck injury (e.g., sprain, fracture, contusion) is not documented, and the patient is receiving follow-up treatment or management for this previously diagnosed injury.

Apply this code when a patient presents for ongoing care (e.g., physical therapy, medication management, re-evaluation) of a neck injury where the initial injury type was not specified, and the encounter is not for the initial treatment. Documentation should clearly state "unspecified neck injury" and indicate a follow-up or subsequent visit.

• Only use this code when the specific type of neck injury cannot be determined from the medical record.
• Ensure the "D" seventh character is appropriate for a subsequent encounter, indicating active treatment or healing phase.
• Avoid using this code if a more specific neck injury diagnosis (e.g., S13.4XXD for neck sprain) is available in the documentation.
