What is the CPT Code for a DEXA Scan?

A DEXA scan (Dual-Energy X-ray Absorptiometry) is a specialized imaging test that measures bone density and helps diagnose conditions such as osteoporosis. To ensure correct medical billing and insurance reimbursement, healthcare providers must use the right CPT code when reporting this procedure.

So, what exactly is the CPT code for a DEXA scan, and why does it matter in medical billing? Let’s break it down.

CPT Codes for DEXA Scans

The most common CPT codes for DEXA scans include:

• 77080 – Dual-energy X-ray absorptiometry, bone density study, 1 or more sites, axial skeleton (e.g., hips, pelvis, spine).
• 77081 – DEXA bone density study, appendicular skeleton (e.g., wrist, heel, forearm).
• 77085 – DEXA bone density study including vertebral fracture assessment.

These codes ensure that the correct type of DEXA scan is billed depending on the location and purpose of the exam.

Why Accurate Coding for DEXA Matters

Accurate CPT coding isn’t just about compliance—it directly impacts provider revenue and patient satisfaction. Submitting the wrong code can lead to:

• Claim denials or delays
• Reduced reimbursement rates
• Compliance risks during audits

That’s why many practices rely on specialized radiology billing services to manage coding, claim submission, and denial management efficiently.

How DEXA Scan CPT Codes Fit into Medical Billing

DEXA scans fall under radiology procedures, meaning providers need to carefully document:

• Patient history and medical necessity
• Exact scan type performed
• Correct CPT code used

A solid foundation in medical billing and coding ensures smooth claim submission and accurate reimbursement. Since DEXA scans are often preventive, insurance coverage may vary, making accurate coding even more critical.

CPT Code 77080 and Revenue Cycle Management

Among DEXA codes, 77080 (axial skeleton scan) is the most frequently used. To optimize reimbursements, providers must integrate accurate coding into their revenue cycle management strategy. This helps reduce claim denials and keeps cash flow consistent.

Final Thoughts

The CPT code for a DEXA scan depends on the type of study performed, with 77080 being the most commonly used. Correct coding ensures providers receive accurate reimbursement while maintaining compliance with payer requirements. By leveraging expert billing solutions, healthcare practices can streamline claim submissions and focus on delivering quality patient care.
