T23.319

Clinical Causes: Contact with thermal sources such as hot surfaces, flames, or scalding liquids Exposure to hot chemicals or acids Electrical burns from electrical appliances or equipment Friction or abrasion combined with heat source Chemical explosions or accidents involving hazardous substances Sudden contact with molten materials

Key Symptoms: Severe pain and throbbing in the affected thumb Charred or leathery skin appearance Loss of sensation in the thumb nail area Swelling and blistering initially, followed by tissue damage Blackened or white tissue indicating dead tissues Possible exposure of underlying tissues or bone in severe cases Loss of nail or destruction of the nail bed

Diagnosis Path: Diagnosing a third-degree burn involves a physical examination by a healthcare professional. The clinician will assess the extent of tissue damage, check for signs of infection, and evaluate nerve damage based on sensation. In some cases, imaging studies such as X-rays may be performed to determine if underlying bones are affected. A detailed history of the injury mechanism can help confirm the severity of the burn. Proper documentation and classification using the ICD-10 coding system assist in ensuring precise medical record keeping and treatment planning.

Treatment Protocols: Immediate cooling of the burn area with sterile, cool (not cold) water to reduce pain and prevent further tissue damage Prompt medical evaluation to determine the need for surgical intervention Debridement to remove dead tissue, preventing infection and promoting healing Surgical procedures such as skin grafts or flap surgery if necessary to restore tissue integrity Pain management using appropriate medications Antibiotics to prevent or treat infection Tetanus prophylaxis if indicated Wound care and dressing changes to maintain cleanliness Rehabilitation exercises and physical therapy following initial healing to maintain thumb mobility Long-term management may include physical therapy and, in some cases, reconstructive surgery
