As a DME provider, imagine renting out a wheelchair to a patient who is suffering with spinal cord injuries. But after 13 months of getting regularly reimbursed by Medicare, you are forced to transfer the ownership of the medical equipment to the patient. This is known as the capped-rental model in DME billing, a Medicare reimbursement structure for durable medical equipment claims.
However, the trickiest part is billing for such equipment and ensuring fair payment for providers. It requires navigating through complex billing nuances, and failing to do so can lead to several financial and compliance risks. However, with expert help such complexities can be managed effectively.
What is the Capped-Rental Model?
A capped-rental model is a Medicare payment structure for Durable Medical Equipment (DME). Under this model, needed medical items are not purchased by patients but rather rented for a maximum of 13 months. After this, ownership automatically transfers to the beneficiary if the equipment is still needed by the patient.
Medicare uses this system to control costs for DME, like wheelchairs, hospital beds, among others. Simply put it allows them to pay a basic rental charge – of around 10% of the allowed purchase rate – for the first 3 months, and 7.5% for the next 4-13 months (for a basic wheelchair, for example). Any balance cost needs to be borne by the user. And the onus of paying for maintenance, repair or supplies remains on the patient, too.
This way, patients do not have to pay hefty purchase amounts to suppliers, which is great for both patients and insurance payers, but can cut down the provider’s cash flow.

How the 13-Month Rental Cycle Works Under Capped DME Rental
The rental phase under this system stays for 13 months for patients covered by the Medicare insurance plan. The key aspects of this phase include:
| Phase | Explanation |
| Payment schedule | Medicare generally covers the first 3 months at 10% of the allowed purchase price, followed by 10 months at 7.5%. |
| Billing modifiers | Specific billing modifiers like KH for the initial, KI for the second and third, and lastly, KJ for the fourth to thirteenth rental months are used to track the progression from initial setup to final payments. |
| Continuous need | The 13 months represent a period of continuous medical necessity, though minor interruptions may not restart the cycle. |
Following these 13 continuous paid months, the supplier must transfer equipment ownership to the beneficiary, and rental payments will cease.
Equipment Covered Under Capped-Rental
Not all DME are covered under the capped-rental model by Medicare. Some of the common items that are covered include:
- Wheelchairs, including standard power ones
- Hospital beds and accessories like side-rails and mattresses
- Oxygen equipment, like concentrators
- Mobility and support devices, like specialized walkers and patient lifts
- Therapeutic equipment, like lymphedema pumps
All this equipment needs to be billed properly under the rental cycle, to ensure accurate and timely reimbursement for providers.
DME Billing Process under Capped-Rental
Just like any other standard medical billing method, DME billing for capped-rental products requires meeting specific guidelines. For example, checking the patient’s eligibility for capped- rental, submitting clinical documents to prove medical necessity, ensuring proper use of HCPCS level II codes and rental month specific modifiers – are all necessary billing steps.
However, what makes billing for such products different is the consideration for rental billing cycles. Billers need to have an in-depth understanding of the rates fixed for each month of the rental cycle for specific DME products to ensure proper reimbursement.
Compliance and Documentation Requirements
To ensure proper reimbursement for capped-rental DME, billers must ensure compliance with several documentation needs. For example, a detailed written order, including the beneficiary’s name, description of the item along with the related HCPCS level II codes, brand names, the physician’s signature and the date of the order – needs to be submitted. Apart from that, proof of delivery and medical necessity documentation also play a crucial role. An inability to submit such documentation accurately can lead to claim rejections.
Common Challenges in DME Billing Under Capped-Rental Model
To develop the best practices for effective billing of DME under this unique Medicare model, billers are required to have a full awareness of common errors. Some of these include:
Assigning the wrong HCPCS level II codes which can create huge billing gaps. For example, the code K0001 refers to a standard wheelchair, and if this is used by a coder to refer to a CPAP device, then a major billing discrepancy will be created. The code will not match the item provided, thereby leading to claim rejections.
Additionally, not using modifiers like KH, KJ, and KI will also not allow payers to identify the rental month, leading to delays and denials.
Without proper documentation, medical necessity cannot be justified, and this can lead to negative outcomes.
Lastly, adhering to payer-specific guidelines plays a huge role in uninterrupted reimbursements. Errors in the same can lead to claim delays and denials. For instance, if a patient suddenly stops using the equipment and then restarts, then a new billing cycle needs to be generated. In such a case, proper justification for the break, along with a new prescription for the DME, will have to be provided.
