Now, PDAC has expanded the requirement to Multi-articulating hands, HCPCS code L6880, which must be completed by December 31, 2021.

The responsibility for accurate coding lies with the patient care facility that selects the product, fits the patient, and bills for the service.

The product/device “Supplier” (defined as an O&P practitioner, O&P patient care facility, or DME Supplier) assumes full responsibility for accurate billing of Ottobock products. It is the Supplier’s responsibility to determine medical necessity; ensure coverage criteria is met; and submit appropriate HCPCS codes, modifiers, and charges for services/products delivered. It is also recommended that Supplier’s contact insurance payer(s) for coding and coverage guidance prior to submitting claims. Ottobock Coding Suggestions and Reimbursement Guides are based on reasonable judgment and are not recommended to replace the Supplier’s judgment. These recommendations may be subject to revision based on additional information or alpha-numeric system changes.

Reimbursement Services and Resources

The Reimbursement staff at Ottobock fields more than 2800 calls from patients and practitioners annually. Many of these calls are requests for documentation to support reimbursement of prosthetic, orthotic, and mobility products and therapies.

After we help a customer solve a challenge, we often create a tool that can help other people navigate the same challenge, for example to help you create proper documentation for billing and coding purposes.

Please note that the responsibility for accurate coding lies with the patient care facility that selects the product, fits the patient, and bills for the service.
