Official coding guidelines
From the ICD-10-CM Official Guidelines for Coding and Reporting, FY 2027 (CMS and NCHS). Links open the PDF at the right page.
- Section I.C.19.d Coding of Burns and Corrosions (page 80), covers T26
Sequence the highest degree burn first and code each site separately, using the highest degree for one site. Code non-healing burns as acute, add codes for infection, and add an external cause code for source, intent, and place.
Other Chapter 19 topics:
- Application of 7th Characters in Chapter 19 (page 77)
- Coding of Injuries (page 78)
- Coding of Traumatic Fractures (page 79)
- Adverse Effects, Poisoning, Underdosing and Toxic Effects (page 82)

T26 MS-DRGs
As the principal diagnosis, the billable codes under T26 group to MS-DRG 124, 125, 604, 605, 949, or 950 (v44.0). Which one applies depends on procedures performed, secondary diagnoses (CC/MCC), and the patient's age and discharge status.
- DRG 124 Other Disorders of the Eye with MCC or Thrombolytic Agent (30 of 90 codes)
- DRG 125 Other Disorders of the Eye without MCC (30 of 90 codes)
- DRG 604 Trauma to the Skin, Subcutaneous Tissue and Breast with MCC (30 of 90 codes)
- DRG 605 Trauma to the Skin, Subcutaneous Tissue and Breast without MCC (30 of 90 codes)
- DRG 949 Aftercare with CC/MCC (30 of 90 codes)
- DRG 950 Aftercare without CC/MCC (30 of 90 codes)

About the condition
Plain-language background from MedlinePlus (National Library of Medicine), not coding guidance.
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.

The structure of your face helps protect your eyes from injury. Still, injuries can damage your eye, sometimes severely enough that you could lose your vision. Most eye injuries are preventable. If you play sports or work in certain jobs, you may need protection.
