    ICD-10-CM Code For Burn And Corrosion Of Lower Limb Except Ankle And Foot: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group T24 includes burns and corrosions of the lower limb excluding the ankle and foot, covering thermal, chemical, and electrical injuries to the thigh, knee, and lower leg that vary by depth and extent. These ICD-10-CM diagnosis codes are used to document clinical scenarios such as superficial versus full-thickness burns, involvement of multiple anatomical layers, and any associated complications like infection or tissue necrosis, capturing disease severity and treatment complexity. Accurate coding within the ICD-10-CM T24 group supports proper claim adjudication and complete clinical documentation for appropriate reimbursement.

    ICD-10-CM T24: Burn And Corrosion Of Lower Limb, Except Ankle And Foot Overview

    The ICD-10-CM T24 group includes codes for burns and corrosions affecting the lower limb excluding the ankle and foot. These diagnoses represent thermal, chemical, or electrical injuries to skin and underlying tissues of the thigh, knee, and lower leg. Accurate coding matters for clinical documentation and reimbursement because severity, depth, and extent of injury influence treatment needs and claim adjudication.

    When to Use

    Use a code from this group when the clinical record documents a burn or corrosion specifically involving the thigh, knee, or lower leg and excludes ankle and foot involvement. Select the code that corresponds to the documented depth, extent, laterality, and any complicating conditions such as infection or presence of necrotic tissue.

    Typical Clinical Scenarios

    • An adult construction worker presents to the emergency department after a workplace accident where hot molten metal splashed onto the anterior and lateral surfaces of the thigh and lower leg, causing full-thickness skin loss with exposed subcutaneous tissue. The patient requires immediate wound debridement, pain control, and tetanus prophylaxis; an acute burn code from this group is assigned to document the burn of the lower limb (excluding ankle and foot) and the initial encounter for treatment. Typical codes: T24.011A, T24.021A
    • An elderly nursing home resident develops a partial-thickness scald burn to the posterior lower leg after an episode of hot water exposure during bathing; the lesion is being managed with outpatient dressings and periodic clinic visits for wound care. Because this is a non-initial encounter for ongoing treatment of the lower limb burn, a subsequent encounter code from this group is used to indicate continued care for the burn site. Typical codes: T24.011D, T24.021D
    • A middle-aged patient with diabetes presents with delayed healing and cellulitis around a previously documented thermal burn on the medial lower leg that occurred weeks earlier; they require inpatient IV antibiotics and assessment for surgical intervention. The burn is now complicated by infection and poor healing, so a code from this group indicating the burn of the lower limb with a sequela or subsequent care status is assigned to capture the complication and current management. Typical codes: T24.011S, T24.021S
