Version 2019 Non-Billable Code

Not Valid for Submission

T24.602 is a "header" nonspecific and non-billable code code, consider using a code with a higher level of specificity for a diagnosis of corrosion of second degree of unspecified site of left lower limb, except ankle and foot. The code is NOT valid for the year 2020 for the submission of HIPAA-covered transactions.

ICD-10: T24.602
Short Description:Corros second deg of unsp site left lower limb, ex ank/ft
Long Description:Corrosion of second degree of unspecified site of left lower limb, except ankle and foot

  • T24.602A - Corrosion of second degree of unspecified site of left lower limb, except ankle and foot, initial encounter
  • T24.602D - Corrosion of second degree of unspecified site of left lower limb, except ankle and foot, subsequent encounter
  • T24.602S - Corrosion of second degree of unspecified site of left lower limb, except ankle and foot, sequela

Code Classification

  • Injury, poisoning and certain other consequences of external causes (S00–T98)
    • Burns and corrosions of external body surface, specified by site (T20-T25)
      • Burn and corrosion of lower limb, except ankle and foot (T24)

Information for Patients


Burns

A burn is damage to your body's tissues caused by heat, chemicals, electricity, sunlight, or radiation. Scalds from hot liquids and steam, building fires and flammable liquids and gases are the most common causes of burns. Another kind is an inhalation injury, caused by breathing smoke.

There are three types of burns:

  • First-degree burns damage only the outer layer of skin
  • Second-degree burns damage the outer layer and the layer underneath
  • Third-degree burns damage or destroy the deepest layer of skin and tissues underneath

Burns can cause swelling, blistering, scarring and, in serious cases, shock, and even death. They also can lead to infections because they damage your skin's protective barrier. Treatment for burns depends on the cause of the burn, how deep it is, and how much of the body it covers. Antibiotic creams can prevent or treat infections. For more serious burns, treatment may be needed to clean the wound, replace the skin, and make sure the patient has enough fluids and nutrition.

General Equivalence Map Definitions
The ICD-10 and ICD-9 GEMs are used to facilitate linking between the diagnosis codes in ICD-9-CM and the new ICD-10-CM code set. The GEMs are the raw material from which providers, health information vendors and payers can derive specific applied mappings to meet their needs.

  • Approximate Flag - The approximate flag is on, indicating that the relationship between the code in the source system and the code in the target system is an approximate equivalent.
  • No Map Flag - The no map flag indicates that a code in the source system is not linked to any code in the target system.
  • Combination Flag - The combination flag indicates that more than one code in the target system is required to satisfy the full equivalent meaning of a code in the source system.
