Code Description

ICD-10 E06.2 is a billable code used to indicate a diagnosis of chronic thyroiditis with transient thyrotoxicosis.

Key Diagnostic Point:

Chronic thyroiditis with transient thyrotoxicosis is a condition characterized by inflammation of the thyroid gland, which can lead to episodes of excessive thyroid hormone production (thyrotoxicosis). This condition is often associated with autoimmune disorders, particularly Hashimoto's thyroiditis, where the immune system attacks the thyroid tissue. The inflammation can cause the thyroid to release stored hormones, resulting in transient hyperthyroid symptoms such as weight loss, increased heart rate, anxiety, and heat intolerance. Over time, chronic thyroiditis may lead to hypothyroidism as the gland becomes damaged and unable to produce adequate thyroid hormones. Diagnosis typically involves thyroid function tests, including serum TSH, free T4, and T3 levels, along with thyroid antibodies to confirm autoimmune involvement. Management may include monitoring thyroid function, symptomatic treatment for hyperthyroid symptoms, and addressing any underlying autoimmune issues.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between transient thyrotoxicosis and chronic hypothyroidism.
  • Need for comprehensive thyroid function tests interpretation.
  • Potential overlap with other thyroid disorders.
  • Documentation of autoimmune markers and their relevance.

Audit Risk Factors

  • Inadequate documentation of thyroid function tests.
  • Failure to document the transient nature of thyrotoxicosis.
  • Misclassification of chronic thyroiditis as a primary hyperthyroid condition.
  • Lack of evidence for autoimmune markers.
