ICD-10 code for goiter
From the official ICD-10-CM alphabetic index entry “Goiter (plunging) (substernal)”. Page updated September 29, 2026.
About coding goiter
The ICD-10-CM code for goiter is E04.9 (Nontoxic goiter, unspecified). The official index lists 44 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on E04.9.
Within E04, choose E04.9 (Nontoxic goiter, unspecified) only when documentation doesn't support a more specific option: nontoxic diffuse goiter (E04.0), nontoxic single thyroid nodule (E04.1), nontoxic multinodular goiter (E04.2) and other specified nontoxic goiter (E04.8).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
In MS-DRG v44.0, it is part of the grouping logic for DRG 643 (Endocrine Disorders with MCC, relative weight 1.6139), DRG 644 (Endocrine Disorders with CC, relative weight 1.0044) and DRG 645 (Endocrine Disorders without CC/MCC, relative weight 0.7459), in MDC 10 (Endocrine, Nutritional and Metabolic Diseases and Disorders), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
