Code Description

ICD-10 E04 is a billable code used to indicate a diagnosis of other nontoxic goiter.

Key Diagnostic Point:

Other nontoxic goiter refers to an enlargement of the thyroid gland that is not associated with hyperthyroidism or malignancy. This condition can arise due to various factors, including iodine deficiency, autoimmune conditions, or as a result of certain medications. Nontoxic goiters can be classified as diffuse or nodular, with the latter often presenting as discrete lumps within the thyroid tissue. Patients may present with a visible swelling in the neck, but many remain asymptomatic. Diagnosis typically involves thyroid function tests, including serum TSH, T3, and T4 levels, to rule out thyroid dysfunction. Imaging studies such as ultrasound may be utilized to assess the size and structure of the goiter. Management may include observation, thyroid hormone replacement, or surgical intervention in cases of significant enlargement or compressive symptoms. Understanding the underlying cause is crucial for appropriate treatment and monitoring.

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between toxic and nontoxic goiter
  • Understanding the underlying causes of goiter
  • Interpreting thyroid function tests accurately
  • Recognizing associated conditions such as hypothyroidism or hyperthyroidism

Audit Risk Factors

  • Inadequate documentation of thyroid function tests
  • Failure to specify the type of goiter (diffuse vs. nodular)
  • Misclassification of goiter as toxic
  • Lack of follow-up documentation for management plans

Documentation Requirements

Thorough documentation of thyroid function tests, imaging results, and clinical findings.

Common Clinical Scenarios

Patients presenting with neck swelling, abnormal thyroid function tests, or incidental findings on imaging.

Billing Considerations

Ensure clarity in distinguishing between nontoxic and toxic goiter, and document any associated symptoms.

Primary Care

Documentation Requirements

Detailed patient history, physical examination findings, and any referrals made to specialists.

Common Clinical Scenarios

Routine check-ups revealing thyroid enlargement or patients reporting symptoms of thyroid dysfunction.

Coding Guidelines

Inclusion Criteria

Use E04 When
  • According to ICD
  • 10 guidelines, E04 should be used when the goiter is not associated with hyperthyroidism or malignancy
  • It is important to document the absence of these conditions clearly

Exclusion Criteria

Do NOT use E04 When
  • Exclusion criteria include any toxic goiter or goiter due to malignancy

Frequently Asked Questions

What is the difference between toxic and nontoxic goiter?

Toxic goiter is associated with hyperthyroidism, while nontoxic goiter does not involve excessive thyroid hormone production and is typically benign.
