The ICD-10 Procedure Coding System (ICD-10-PCS) is a US system of medical classification used for procedural coding.The Centers for Medicare and Medicaid Services, the agency responsible for maintaining the inpatient procedure code set in the U.S., contracted with 3M Health Information Systems in 1995 to design and then develop a procedure classification system to replace Volume 3 of ICD-9-CM.
The tests are classified by speciality field, conveying in which ward of a hospital or by which specialist doctor these tests are usually performed. The ICD-10-CM is generally the most widely used standard by insurance companies and hospitals who have to communicate with one another, for giving an overview of medical tests and procedures.

A thyroidectomy is an operation that involves the surgical removal of all or part of the thyroid gland. In general surgery , endocrine or head and neck surgeons often perform a thyroidectomy when a patient has thyroid cancer or some other condition of the thyroid gland (such as hyperthyroidism ) or goiter.
Screening for thyroid disease in patients without symptoms is a debated topic although commonly practiced in the United States. [8] If dysfunction of the thyroid is suspected, laboratory tests can help support or rule out thyroid disease. Initial blood tests often include thyroid-stimulating hormone (TSH) and free thyroxine (T4). [9]
While TSH-based screening will identify the most common causes, the addition of T 4 testing is required to pick up the rarer central causes of neonatal hypothyroidism. [30] If T 4 determination is included in the screening done at birth, this will identify cases of congenital hypothyroidism of central origin in 1:16,000 to 1:160,000 children.
