Diagnosis Overview

What is Thyroid Mass?
Essential facts and insights about Thyroid Mass

Key Clinical Considerations:

  • Palpable thyroid nodule or mass
  • Hoarseness or voice changes
  • Difficulty swallowing or breathing
  • Thyroid function abnormalities (hyperthyroidism or hypothyroidism)
  • Neck pain or discomfort

Clinical Information

Clinical Criteria & Documentation Requirements

  • Patient history including symptoms and duration
  • Results of thyroid function tests (TSH, T3, T4)
  • Imaging studies (ultrasound, CT, MRI) findings
  • Biopsy results if applicable
  • Physical examination details including size and consistency of the mass

Coding Guidelines

Usage Guidelines & Examples

  • Usage guidelines: Use specific codes based on the nature of the thyroid mass (benign vs malignant).
  • Common errors: Misclassifying benign nodules as malignant or vice versa.

Code Exclusions

Important Exclusions

  • Thyroiditis (E06.3)
  • Thyroid cancer staging codes (C73.9)
