Final answer:
The specific CPT code for an ultrasound bone density measurement is not provided, but the procedure relates to bone densitometry codes. DEXA is a method for assessing bone density and body composition, using low-dose X-ray beams and mathematical formulas to estimate fat content.
Step-by-step explanation:
The CPT code for an ultrasound bone density measurement and interpretation at peripheral sites, using any method, has not been specified. However, the description fits within the range of CPT codes related to bone densitometry.
Dual-energy X-ray absorptiometry (DEXA) is a known method for measuring bone density. It also evaluates body composition by determining fat content. Two low-dose X-ray beams are directed through the body, and the absorbed energy indicates the proportion of bone, lean tissue, and fat mass. Standard mathematical formulas are then applied to calculate fat content based on the amount of energy absorbed, providing a reliable estimate.
