X52-X58 — Accidental exposure to other specified factors
ICD-10-CM codes X52-X58 cover accidental exposure to other specified factors, within external causes of morbidity. The block holds 8 codes across 2 categories, of which 6 are billable and 2 are header codes that cannot be submitted on a claim. 8 of them (100%) require a 7th character.
The 7th character in X52-X58
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. 8 of the 8 codes here take one.
- A
- initial encounter
- D
- subsequent encounter
- S
- sequela
