General Requirements for Insurance Coverage of Prolia (Denosumab) Shot
Most insurance companies require documentation of high fracture risk and/or failure of first-line therapies before covering Prolia (denosumab) for osteoporosis treatment. 1, 2
Patient Eligibility Criteria
High-Risk Patient Categories
Insurance coverage typically requires patients to meet one or more of these criteria:
Postmenopausal women with osteoporosis at high risk for fracture, defined as:
- History of osteoporotic fracture
- Multiple risk factors for fracture
- T-score ≤ -2.5 (or lower, depending on insurer)
- Failure of or intolerance to other osteoporosis therapies 2
Men with osteoporosis at high risk for fracture with:
- History of osteoporotic fracture
- Multiple risk factors for fracture
- Failure of or intolerance to other osteoporosis therapies 2
Glucocorticoid-induced osteoporosis in men and women who are:
Patients with bone loss due to:
- Androgen deprivation therapy for prostate cancer
- Aromatase inhibitor therapy for breast cancer 2
Documentation Requirements
Most insurers require:
Bone mineral density (BMD) testing via DXA scan showing osteoporosis (T-score ≤ -2.5 or lower) 1
FRAX score calculation showing:
- ≥20% 10-year risk of major osteoporotic fracture, or
- ≥3% 10-year risk of hip fracture 1
Prior treatment failure documentation:
For very high-risk patients (T-score ≤ -3.5, prior fracture, or FRAX score ≥30% for major osteoporotic fracture), some insurers may approve Prolia as first-line therapy 1
Common Coverage Limitations
- Prior authorization is almost always required
- Quantity limits typically restrict coverage to one 60mg injection every 6 months
- Step therapy protocols often require trial of oral bisphosphonates first
- Reauthorization requirements may include:
- Documentation of continued need
- Evidence of treatment response (stable or improved BMD)
- Absence of adverse effects 4
Special Considerations
Chronic Kidney Disease
- For patients with advanced kidney disease (eGFR <30 mL/min/1.73m²), additional testing is required:
- Intact parathyroid hormone (iPTH)
- Serum calcium
- Vitamin D levels
- Assessment for chronic kidney disease-mineral bone disorder (CKD-MBD) 2
Rebound Effect Considerations
- Some insurers may require a plan for transitioning to another therapy after Prolia discontinuation due to the risk of rebound bone loss and multiple vertebral fractures 5
Practical Tips for Approval
- Clearly document all fracture risk factors
- Include T-scores from all measured sites (spine, hip, femoral neck)
- Document specific reasons for bisphosphonate failure or intolerance
- For glucocorticoid users, document exact dosage and expected duration of therapy 3
- Include vertebral fracture assessment (VFA) or spinal x-rays showing any existing fractures 1
Common Pitfalls to Avoid
- Incomplete documentation of prior therapy failures
- Missing laboratory values needed to rule out secondary causes of osteoporosis
- Failure to document contraindications to oral bisphosphonates when requesting first-line approval
- Not addressing the need for calcium and vitamin D supplementation in the treatment plan 1
Remember that specific requirements vary by insurance provider, plan type, and state regulations. Prior authorization forms specific to each insurer should be carefully reviewed before submission.
