Summary & Overview
HCPCS G0130: Peripheral Bone Density Study (Single-Energy X-Ray Absorptiometry)
HCPCS Level II code G0130 denotes a single energy x-ray absorptiometry (SEXA) bone density study of one or more appendicular (peripheral) sites such as the radius, wrist, or heel. This imaging procedure is used to assess peripheral bone mineral density and can inform fracture risk assessment, monitoring of bone health, and clinical decision-making. Nationally, coding for peripheral bone density studies matters for appropriate claims processing, clinical documentation, and alignment with diagnostic workflows.
Key payers commonly involved in coverage and reimbursement for this service include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of coverage considerations, expected sites of service, common modifiers used with imaging services, and the clinical context in which G0130 is applied. The publication summarizes benchmarks and payer patterns where available, outlines relevant policy and billing nuances for peripheral bone density testing, and clarifies what the code encapsulates clinically. Data not available in the input will be noted where applicable.
Billing Code Overview
HCPCS Level II code G0130 describes a single energy x-ray absorptiometry (SEXA) bone density study of one or more sites on the appendicular skeleton (peripheral), such as the radius, wrist, or heel. The service type is an imaging study for measurement of bone mineral density using single-energy x-ray absorptiometry. The typical site of service is an outpatient imaging center or clinic performing peripheral bone density measurements.
Clinical & Coding Specifications
Clinical Context
A 68-year-old woman with a history of postmenopausal osteoporosis presents for bone density assessment focused on peripheral sites due to inability to undergo central dual-energy X-ray absorptiometry (DXA) of the hip and spine (for example, patient body habitus, recent hip replacement hardware, or limited mobility). The clinician orders a single energy x-ray absorptiometry (SEXA) peripheral study of the distal radius and heel to evaluate bone mineral density and fracture risk. The patient checks in at the outpatient radiology or bone densitometry clinic. A certified radiologic technologist reviews clinical indications, obtains a focused history (prior fragility fractures, osteoporosis therapy, recent contrast studies), verifies no contraindications, and positions the limb on the peripheral densitometer. The technologist performs the peripheral scan, documents site(s) imaged (e.g., radius, calcaneus), acquires image and measurement data, and stores the results to the PACS or densitometry software. The interpreting physician (radiologist, endocrinologist, or rheumatologist) reviews the images and generates a signed report with measured bone density values and T-scores/Z-scores for the appendicular site(s). Results are routed to the ordering provider for clinical management. Billing uses G0130 for the single-energy peripheral bone density study; appropriate modifier(s) are appended per payer rules when applicable (for example, professional vs technical component). Typical sites of service are outpatient radiology departments, hospital outpatient imaging centers, or freestanding bone densitometry clinics. Common clinical indications include screening for osteoporosis in patients unable to undergo central DXA, monitoring response to therapy when peripheral measures are used, and evaluation after peripheral fragility fractures.
