2025 ICD-10-CM code C73
(Valid) Effective Date: N/A Neoplasms 2: Neoplasms (C00-D49) Feed
Malignant neoplasm of thyroid gland. Use additional code to identify any functional activity.
Medical necessity is established by the presence of a malignant thyroid neoplasm confirmed by histopathology. Treatment is medically necessary to prevent the spread of cancer and preserve life.
Patients with malignant neoplasm of the thyroid gland may present with a neck mass, enlarged lymph nodes, cough, voice changes, ear and throat pain, and difficulty breathing or swallowing. The cancer can spread to lymph nodes and other parts of the body. Diagnosis involves physical examination, blood tests for thyroid hormone levels, biopsy, and imaging tests (ultrasound, X-ray, CT, MRI, PET) for staging.
In simple words: Malignant neoplasm of the thyroid gland is a type of cancer that affects the thyroid, a gland in your neck that produces hormones. Women are more likely to get it than men. Some things that can increase your risk include your genes, a family history of goiter (an enlarged thyroid), and past radiation treatments.
Malignant neoplasm of the thyroid gland refers to the abnormal growth of thyroid gland cells. This condition is more prevalent in females. Risk factors include genetic predisposition, family history of goiter, and prior exposure to radiation therapy.
Example 1: A 45-year-old female presents with a palpable nodule in the thyroid gland, confirmed by ultrasound and fine-needle aspiration biopsy as papillary thyroid carcinoma. C73 is assigned as the primary diagnosis., A 60-year-old male with a history of radiation exposure in childhood develops hoarseness and difficulty swallowing. A biopsy reveals anaplastic thyroid carcinoma. C73 is assigned., A 50-year-old female undergoes a total thyroidectomy for a follicular thyroid carcinoma. The pathology report confirms the diagnosis, and C73 is assigned.
Documentation should include physical exam findings, thyroid function tests, biopsy results, imaging reports, and operative notes (if applicable). The type and stage of the thyroid cancer should be specified.
