2027 ICD-10-CM Diagnosis Code T27Burn and corrosion of respiratory tract
T27 is a non-billable ICD-10-CM category code for burn and corrosion of respiratory tract, so it cannot be submitted on claims. Use a more specific code from this category instead, such as T27.0XXA, T27.0XXD, T27.0XXS, and T27.1XXA.

Specific Coding for Burn and corrosion of respiratory tractOverview
Non-specific codes like T27 require more characters. Use one of these billable codes instead:
T27.0 for Burn of larynx and trachea
T27.1 for Burn involving larynx and trachea with lung
T27.2 for Burn of other parts of respiratory tract
T27.3 for Burn of respiratory tract, part unspecified
T27.4 for Corrosion of larynx and trachea
T27.5 for Corrosion involving larynx and trachea with lung
T27.6 for Corrosion of other parts of respiratory tract
T27.7 for Corrosion of respiratory tract, part unspecified
Coding GuidelinesGuidance
The ICD-10-CM makes a distinction between burns and corrosions. The burn codes are for thermal burns, except sunburns, that come from a heat source, such as a fire or hot appliance. The burn codes are also for burns resulting from electricity and radiation. Corrosions are burns due to chemicals. The guidelines are the same for burns and corrosions.
Sequence first the code that reflects the highest degree of burn when more than one burn is present.
- When the reason for the admission or encounter is for treatment of external multiple burns, sequence first the code that reflects the burn of the highest degree.
- When a patient has both internal and external burns, the circumstances of admission govern the selection of the principal diagnosis or first-listed diagnosis.
- When a patient is admitted for burn injuries and other related conditions such as smoke inhalation and/or respiratory failure, the circumstances of admission govern the selection of the principal or first-listed diagnosis.
Burns of the eye and internal organs (T26-T28) are classified by site, but not by degree.
Classify burns of the same local site (three-character category level, T20-T28) but of different degrees to the subcategory identifying the highest degree recorded in the diagnosis.
The appropriate 7th character is to be added to each code from block Burn and corrosion of respiratory tract (T27). Use the following options for the applicable episode of care:
- A - initial encounter
- D - subsequent encounter
- S - sequela

Instructional NotesGuidance
Instructions from the official ICD-10-CM Tabular List that apply to T27: its own notes plus those printed at block T20-T32 and Chapter 19. A note printed at a category, block or chapter applies to every code under it.
Includes
Further defines, or gives examples of, the content of the category.
- burns (thermal) from electrical heating appliances
- burns (thermal) from electricity
- burns (thermal) from flame
- burns (thermal) from friction
- burns (thermal) from hot air and hot gases
- burns (thermal) from hot objects
- burns (thermal) from lightning
- burns (thermal) from radiation
- chemical burn [corrosion] (external) (internal)
- scalds
Excludes2
Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.
Use Additional Code
Add a second code, after this one, to fully describe the condition.
- code to identify any retained foreign body, if applicable (Z18.-)
Notes
General instructions on how these codes are used.
- Use secondary code(s) from Chapter 20, External causes of morbidity, to indicate cause of injury. Codes within the T section that include the external cause do not require an additional external cause code
- The chapter uses the S-section for coding different types of injuries related to single body regions and the T-section to cover injuries to unspecified body regions as well as poisoning and certain other consequences of external causes.
7th Character
Every code in the category takes a 7th character from the listed values, with the placeholder X filling any empty positions before it.
- The appropriate 7th character is to be added to each code from category T27
- Ainitial encounter
- Dsubsequent encounter
- Ssequela

Patient EducationClinical
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.

Questions About T27Overview
What is the ICD-10 code for burn and corrosion of respiratory tract?
T27 is the ICD-10-CM category for burn and corrosion of respiratory tract, but it is a non-billable header: claims need a more specific code from this category, listed on this page.
Is T27 (Burn and corrosion of respiratory tract) a billable code?
No. This is a category header that groups the codes for burn and corrosion of respiratory tract, and headers cannot be submitted on claims. Claims for burn and corrosion of respiratory tract need a more specific code from this category, such as T27.0XXA, T27.0XXD, and T27.0XXS.
