Iodine-deficiency related thyroid disorders and allied conditions (E01)

The ICD-10 codes starting with E01 are specifically used to classify thyroid disorders caused by iodine deficiency. These codes help identify various types of goiter and related thyroid conditions that occur due to insufficient iodine intake.

These codes cover several clinically important forms of thyroid enlargement, such as E01.0 for diffuse (endemic) goiter, often called simple goiter or diffuse endemic goiter. The code E01.1 refers to multinodular (endemic) goiter, also known as multinodular goiter or iodine-deficiency-related multinodular endemic goiter. When the specific type of iodine-deficiency goiter is not detailed, E01.2 for unspecified endemic goiter is used. Additionally, E01.8 captures other iodine-deficiency thyroid disorders like iodine hypothyroidism and iodine deficiency syndrome. Understanding these synonyms aids coders and healthcare professionals in selecting the accurate ICD-10 code for patients presenting with iodine-related thyroid abnormalities.

Instructional Notations

Type 1 Excludes

A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

  • congenital iodine-deficiency syndrome E00
  • subclinical iodine-deficiency hypothyroidism E02
