T26-T28 — Burns and corrosions confined to eye and internal organs
ICD-10-CM codes T26-T28 cover burns and corrosions confined to eye and internal organs, within injury, poisoning and certain other consequences of external causes. The block holds 241 codes across 3 categories, of which 168 are billable and 73 are header codes that cannot be submitted on a claim. 241 of them (100%) require a 7th character.
The 7th character in T26-T28
A code in this block is not complete without its 7th character, and a missing one is a rejected claim rather than a denied one: the clearinghouse never passes it on. 241 of the 241 codes here take one.
- A
- initial encounter
- D

What else to watch in T26-T28
- 96 codes are laterality-specific. They come in left and right pairs, and the pair is mutually exclusive on a single site: coding both without a bilateral code is a contradiction a scrubber should catch before the payer does.
- 165 codes are named in Medicare coverage policies. An LCD or NCD lists them as supporting medical necessity, or explicitly as not supporting it. Which applies depends on the MAC for your state.
