Code Description

ICD-10 E07.0 is a billable code used to indicate a diagnosis of hypersecretion of calcitonin.

Key Diagnostic Point:

Hypersecretion of calcitonin is a condition characterized by excessive production of calcitonin, a hormone produced by the parafollicular cells (C cells) of the thyroid gland. Calcitonin plays a crucial role in calcium homeostasis by lowering blood calcium levels through its actions on bone and kidney. This condition is often associated with medullary thyroid carcinoma, a type of thyroid cancer that arises from C cells. Patients may present with symptoms related to hypercalcemia, such as nausea, vomiting, abdominal pain, and neurological disturbances. Diagnosis typically involves measuring serum calcitonin levels, which can be significantly elevated in affected individuals. Thyroid function tests, including TSH, T3, and T4 levels, are essential to rule out other thyroid disorders such as hyperthyroidism or hypothyroidism. Management may include surgical intervention, particularly if a neoplasm is present, and monitoring of calcitonin levels postoperatively. Understanding the interplay between calcitonin secretion and other thyroid hormones is vital for accurate diagnosis and treatment.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Requires understanding of thyroid anatomy and physiology
  • Involves differentiation from other thyroid disorders
  • Need for precise laboratory test interpretation
  • Potential association with malignancy (medullary thyroid carcinoma)

Audit Risk Factors

  • Inadequate documentation of calcitonin levels
  • Failure to document associated symptoms
  • Misdiagnosis due to overlapping symptoms with other thyroid disorders
  • Lack of follow-up documentation post-surgery

Coding Guidelines

Inclusion Criteria

Use E07.0 When
  • According to ICD
  • 10 guidelines, E07
  • 0 should be used when there is clear documentation of hypersecretion of calcitonin, and it should not be used if the condition is secondary to other known causes
  • It is important to ensure that all relevant laboratory tests and clinical findings are documented

Exclusion Criteria

Do NOT use E07.0 When

Frequently Asked Questions

What are the common symptoms of hypersecretion of calcitonin?

Common symptoms include nausea, vomiting, abdominal pain, and neurological disturbances due to hypercalcemia.

How is hypersecretion of calcitonin diagnosed?
