Frequently asked questions

CPT Code 77080 refers to dual-energy X-ray absorptiometry (DXA) of the axial skeleton to evaluate bone mineral density. Healthcare professionals use it for bone density testing to diagnose osteoporosis, assess fracture risk, and support ongoing patient care.

Diagnosis codes supporting a DXA scan include osteoporosis, osteopenia, bone loss, and high-risk conditions like current pathological fracture or chronic steroid use. The bone density international classification and diagnosis codes should always align with payer policies for coverage.

Generally, CPT Code 77080 is covered once for an initial bone mass measurement, with repeat scans allowed only if medically necessary for future monitoring or treatment assessment. The billing frequency may vary depending on the payer's policy and the patient's condition.
