What does medical code 84443 stand for?

Answer 1

CPT code 84443 refert to Thyroid stimulating hormone (TSH).
The TSH test is performed to determine the thyroid function, identify any type of thyroid disorder, and detect any symptoms like hypo– or hyperthyroidism. For newborns, this is performed to detect an underactive thyroid. A blood sample is collected from a vein in the arm (in adults) or from the heel (in newborn) and tested for TSH by various immunoassay techniques. A high TSH result usually means an underactive thyroid gland not responding properly to the stimulation of TSH due to some thyroid disorder. A low TSH result generally indicates an overactive thyroid gland (hyperthyroidism).

With an antiseptic, the physician or the healthcare provider cleans the skin where blood is to be drawn. Blood is usually taken from a vein at the arm or the back of the hand. An elastic band is wrapped tightly around the upper arm so that the vein at the arm swells suitably. Next, a needle is inserted into the vein and around 5 ml of blood is drawn out into a collection tube. The needle is removed and the puncture site is closed properly. In newborns, the blood is drawn from the heel by pricking it with a lancet. The collected blood specimen is then examined using procedures like radioimmunoassay (RIA), enzyme immunoassay with monoclonal antibodies, etc. A high value of TSH indicates hypothyroidism or an underactive thyroid, whereas a low TSH result indicates hyperthyroidism or over–activity of thyroid.

The TSH test measures the amount of thyroid stimulating hormone (TSH) produced by the pituitary gland. TSH controls the production of T3 and T4 hormone by the thyroid gland. The normal value of TSH in blood is 0.4 – 4.0 mlU/L.
