ICD-10 Code for Thyrotoxicosis
Also indexed as (recurrent)
The ICD-10-CM code for thyrotoxicosis is E05.90 — Thyrotoxicosis, unspecified without thyrotoxic crisis or storm. This is the code the Alphabetic Index gives for thyrotoxicosis with no further qualifier, valid for FY2027 (October 1, 2026 – September 30, 2027).
E05.90 is billable but unspecified. If the documentation names a type, site or cause, one of the more specific codes below is likely expected.
Which thyrotoxicosis code should you use?
The Alphabetic Index lists 17 codes under Thyrotoxicosis. 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.
