CPT® Code 84127

Deleted

The CPT® Code 84127 refers to a qualitative test performed on feces to detect the presence of porphyrins. Porphyrins are organic compounds that play a crucial role in the formation of heme, an essential component of hemoglobin, which is responsible for transporting oxygen in the blood. This test is significant as elevated levels of porphyrins in feces can indicate various medical conditions, including lead poisoning, liver disease, or porphyria. Porphyria is an inherited metabolic disorder characterized by a deficiency of enzymes involved in the heme synthesis pathway, leading to the accumulation of porphyrins in the body. To confirm a diagnosis of porphyria, healthcare providers often require a comprehensive assessment that includes the determination of porphyrin levels in urine, feces, and blood. The test involves obtaining a random stool sample, which is then analyzed using quantitative high-performance liquid chromatography (HPLC). Additionally, the HemoQuant test may be reported in conjunction with CPT® Code 84126, where the stool sample is evaluated using fluorescence quantitation to provide further insights into porphyrin levels.
