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

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group T25 includes burns and corrosions of the ankle and foot, covering thermal, chemical, or electrical injuries of varying depth and laterality. These ICD-10-CM diagnosis codes are used to document clinical scenarios that capture burn severity, affected anatomical site, and any complications or full-thickness involvement relevant to the ankle and foot. Accurate coding within the ICD-10-CM T25 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    ICD-10-CM T25: Burn And Corrosion Of Ankle And Foot Overview

    The ICD-10-CM T25 group represents burns and corrosions specifically affecting the ankle and foot, including varying depths and extents of thermal and chemical injury. These diagnoses target the integumentary system of the lower extremity and distinguish degrees of tissue damage and laterality. Accurate coding matters for clinical documentation and supports appropriate reimbursement by reflecting severity and required treatment intensity.

    When to Use

    Use a code from this group when documentation indicates a burn or corrosive injury specifically involving the ankle or foot and the record specifies depth, extent, or laterality. Select the code that matches the documented degree of burn, any associated complications, and whether the injury is to the right, left, or unspecified side.

    Typical Clinical Scenarios

    • An adult presents to the emergency department after accidentally spilling hot cooking oil onto the dorsum of the foot and lateral ankle; the patient has partial-thickness burns with blistering and pain localized to the ankle and foot area, requiring wound debridement and acute burn care. A diagnosis from this group is assigned to identify the anatomic site and extent of the burn for acute management and documentation. Typical codes: T25.012A, T25.019A
    • An elderly diabetic patient in an outpatient wound clinic has a nonhealing, healed-burn scar on the plantar surface of the foot from a prior thermal injury months earlier; the scar tissue causes recurrent breakdown and chronic ulceration requiring regular dressing changes and offloading. A code from this group is used to indicate the sequelae or later encounter related to the prior ankle/foot burn and to guide ongoing wound care and monitoring. Typical codes: T25.011D, T25.019D
    • A construction worker sustains an industrial electrical burn to the ankle and foot with full-thickness tissue loss and exposure of underlying structures; he is admitted for surgical excision and grafting and has a subsequent encounter for complications of the initial burn (infection and delayed healing). Group-specific codes are used to capture the site, severity (full-thickness), and the encounter type for operative and complication management. Typical codes: T25.031A, T25.039D
