2025 ICD-10-CM code T33.09
(Active) Effective Date: N/A Injury, poisoning and certain other consequences of external causes - Frostbite 19 Feed
Superficial frostbite of other part of head.
Medical necessity for treatment is established by the diagnosis of frostbite. The severity of the condition dictates the level of care required, ranging from first aid measures to more extensive wound care or surgery.
Clinicians diagnosing and treating frostbite injuries should document the extent and location of tissue damage, including whether it is superficial or deep frostbite. They are responsible for providing appropriate medical care, which might involve pain management, wound care, and preventing further complications.
In simple words: This code represents a mild form of frostbite affecting the head, excluding the ears, nose, chin, forehead, scalp, and cheeks. It involves superficial damage to the skin due to exposure to cold temperatures.
Superficial frostbite of other part of head. This indicates frostbite with partial thickness skin loss affecting a part of the head other than the ear, nose, chin, forehead, scalp, or cheek.
Example 1: A patient presents with numbness and redness on the back of their head after prolonged exposure to cold weather. Upon examination, the physician diagnoses superficial frostbite, limited to the skin's surface, and excludes deeper tissue damage., A skier falls and hits the side of their head against a tree. The exposed skin area develops superficial frostbite due to low temperatures. The attending physician documents the frostbite alongside the head injury., A person experiencing homelessness presents to the ER during a winter storm with complaints of headache. Examination reveals superficial frostbite on the temple area. The attending physician documents the frostbite and provides treatment for cold exposure.
Documentation should include the location and depth of the frostbite (superficial vs. deep), presence of any blisters or skin discoloration, associated symptoms (e.g., numbness, pain), and the circumstances leading to cold exposure. Photographs might be helpful to track the progression of the injury.
** This code specifically refers to superficial frostbite. If the frostbite involves deeper tissue damage or necrosis, a different code from the T33-T34 range should be used. Always ensure proper documentation and coding to reflect the specific site and severity of the frostbite.
