Common Language Description

A laboratory test identified by CPT® Code 82649 is utilized to measure the concentration of dihydromorphinone in the bloodstream. Dihydromorphinone is a highly potent narcotic analgesic, which is a type of medication used to relieve pain. It is derived from a hydrogenated ketone of morphine, making it chemically related to this well-known opioid. This medication is typically prescribed for individuals experiencing moderate to severe pain, providing significant relief in various clinical scenarios. Dihydromorphinone can be administered in different ways, including oral ingestion or through injection, depending on the patient's needs and the clinical setting. It is important to note that dihydromorphinone may be marketed under the brand name Dilaudid, which is recognized in the pharmaceutical industry. To perform this test, a blood sample is collected through a procedure known as venipuncture, which is separately reportable. The primary objective of this laboratory test is to quantify the amount of dihydromorphinone present in the blood, aiding healthcare providers in monitoring therapeutic levels and ensuring patient safety during treatment.
