This prospective longitudinal study compares outcomes between Medicare beneficiaries receiving percutaneous image-guided lumbar decompression (PILD), by using the mild® Procedure and a control group of patients receiving interspinous spacers for the treatment of lumbar spinal stenosis (LSS) with neurogenic claudication (NC).
Patients diagnosed with LSS with NC and treated with either the mild® Procedure or a spacer were identified in the Medicare claims database. The study included 2,229 patients in the mild® group and 3,401 patients who were implanted with interspinous spacers.
This comprehensive study of real-world Medicare claims data demonstrated a significantly lower rate of harms for the mild® Procedure compared to interspinous spacers for patients diagnosed with LSS with NC, and a similar rate of subsequent interventions during 2-year follow-up. The rate of harms for those treated with the mild® Procedure was less than half that of patients implanted with a spacer during 2-year follow-up.
These outcomes together with the lower healthcare cost burden for patients receiving mild® is an important element of decision making for treatment of patients early in the LSS continuum of care.

Treatment options shown are commonly offered once conservative therapies (e.g., physical therapy, pain medications, chiropractic) are not providing adequate relief. This is not intended to be a complete list of all treatments available. Doctors typically recommend treatments based on their safety profile, typically prioritizing low risk/less aggressive procedures before higher risk/more aggressive procedures, but will determine which treatments are appropriate for their patients.
Although the complication rate for the mild® Procedure is low, as with most surgical procedures, serious adverse events, some of which can be fatal, can occur, including heart attack, cardiac arrest (heart stops beating), stroke, and embolism (blood or fat that migrates to the lungs or heart). Other risks include infection and bleeding, spinal cord and nerve injury that can, in rare instances, cause paralysis. This procedure is not for everyone. Physicians should discuss potential risks with patients. For complete information regarding indications for use, warnings, precautions, and methods of use, please reference the devices’Instructions for Use.
Patient stories on this website reflect the results experienced by individuals who have undergone the mild® Procedure. Patients are not compensated for their testimonial. The mild® Procedure is intended to treat lumbar spinal stenosis (LSS) caused by ligamentum flavum hypertrophy. Although patients may experience relief from the procedure, individual results may vary. Individuals may have symptoms persist or evolve or other conditions that require ongoing medication or additional treatments. Please consult with your doctor to determine if this procedure is right for you.
Reimbursement, especially coding, is dynamic and changes every year. Laws and regulations involving reimbursement are also complex and change frequently. Providers are responsible for determining medical necessity and reporting the codes that accurately describe the work that is done and the products and procedures that are furnished to patients. For this reason, Vertos Medical strongly recommends that you consult with your payers, your specialty society, or the AMA CPT regarding coding, coverage and payment.
Vertos Medical cannot guarantee coding, coverage, or payment for products or procedures. View our Billing Guide.
