ICD-10-CM Code For Other Nontoxic Goiter: Group Overview

The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group E04 includes nontoxic goiters and related noninflammatory, nonmalignant thyroid enlargements such as simple goiter and multinodular goiter without thyrotoxicosis. These ICD-10-CM diagnosis codes are used to document clinical encounters for thyroid enlargement where hormone levels are normal and there is no malignancy or inflammation, capturing disease distribution and nodularity. Accurate coding within the ICD-10-CM E04 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

ICD-10-CM E04: Other Nontoxic Goiter Overview

The ICD-10-CM E04 group includes diagnoses for noninflammatory, nonmalignant enlargement of the thyroid gland not associated with thyroid hormone excess. These conditions affect the endocrine system and can impact neck anatomy and function. Accurate coding matters because it supports complete clinical documentation and appropriate reimbursement for services related to evaluation and management of thyroid enlargement.

When to Use

Use a code from this group when a patient has documented thyroid enlargement described as nontoxic, simple, or multinodular and there is no concurrent thyrotoxicosis, thyroiditis, or malignancy. These codes apply for encounters involving evaluation, monitoring, or management of goiter without biochemical hyperthyroidism or inflammatory disease.

ICD-10-CM Codes

ICD-10-CM Code	Description
E04.0	Nontoxic diffuse goiter
E04.1	Nontoxic single thyroid nodule
E04.2	Nontoxic multinodular goiter
E04.8	Other specified nontoxic goiter
E04.9	Nontoxic goiter, unspecified

DRG Codes

DRG Code	Description
011	Tracheostomy for Face, Mouth and Neck Diagnoses or Laryngectomy with MCC
012	Tracheostomy for Face, Mouth and Neck Diagnoses or Laryngectomy with CC
013	Tracheostomy for Face, Mouth and Neck Diagnoses or Laryngectomy without CC/MCC
643	Endocrine Disorders with MCC
644	Endocrine Disorders with CC
645	Endocrine Disorders without CC/MCC

Typical Clinical Scenarios

A middle-aged woman presents to primary care with a slowly enlarging, painless anterior neck mass noticed over several months, with no signs of thyrotoxicosis or hypothyroidism. Examination and ultrasound confirm a diffuse non-toxic enlargement of the thyroid consistent with simple or multinodular goiter without functional thyroid hormone abnormality; this is managed as a chronic, non-toxic thyroid enlargement. Typical codes: E04.1, E04.2
An elderly man is evaluated in the emergency department for progressive dyspnea and dysphagia due to a large goiter causing compressive symptoms; thyroid function tests are normal. Imaging shows a substernal extension of the non-toxic goiter producing airway compromise, prompting urgent referral for surgical management; the diagnosis reflects a non-toxic goiter with compressive presentation. Typical codes: E04.0, E04.1
A patient with long-standing non-toxic goiter is seen during a routine endocrinology visit where multiple thyroid nodules are monitored for size change but thyroid hormone levels remain euthyroid. The visit documents multinodular non-toxic goiter as an ongoing comorbidity affecting surveillance and treatment decisions; coding captures the chronic nontoxic goiter diagnosis. Typical codes: E04.2, E04.9
