ICD-10 Code for Exposure

Also indexed as (to)

The ICD-10-CM code for exposure is T75.89 — Other specified effects of external causes. This is the code the Alphabetic Index gives for exposure with no further qualifier, valid for FY2027 (October 1, 2026 – September 30, 2027).

Not billable

T75.89 cannot be submitted on a claim. It is a header code, so a more specific code from the list below is required.

Which exposure code should you use?

The Alphabetic Index lists 67 codes under Exposure. Which one applies depends on the qualifier documented in the record — the type, site, cause, or associated condition. Find the qualifier below, then verify the code in the Tabular List before using it.
