Open bite of thyroid gland, initial encounter

This code signifies an open wound to the thyroid gland, typically caused by a penetrating injury such as a stab wound or gunshot. It indicates that the gland itself has been directly traumatized and exposed to the external environment. This is the initial presentation of such an injury.

Apply this code when documentation clearly states an open wound directly affecting the thyroid gland, and the patient is presenting for the initial treatment of this injury. Supporting documentation would include operative reports, emergency department notes, or physician progress notes detailing the nature and location of the wound.

• Ensure the documentation specifies "open" to differentiate from closed injuries.
• Verify this is the "initial encounter" for treatment; subsequent care would use a different seventh character.
• Code any associated foreign body or nerve damage separately.
