Capped Rental
A Medicare reimbursement model where a supplier rents certain DME items for a defined maximum period, typically 13 months, after which ownership transfers to the beneficiary.
Capped rental is the primary Medicare reimbursement model for many non-oxygen DME items, including hospital beds, wheelchairs, and CPAP equipment. In general, Medicare pays a monthly rental fee for up to 13 months of continuous use. After the 13th paid rental month, title transfers to the beneficiary.
For the supplier, tracking each unit's rental history, including when month 1 began for each beneficiary, is essential for billing accuracy and for understanding whether the unit remains supplier-owned or has transferred to the beneficiary.
How the 13-month capped rental timeline works
Medicare generally makes monthly rental payments for a covered capped-rental item during a period of continuous use, for no more than 13 months. The fee-schedule amount is higher for months 1 through 3 and lower beginning with month 4. After the 13th paid rental month, the beneficiary takes ownership of the equipment.
The rental month is tied to the beneficiary's period of continuous use, not simply to how long a supplier has owned the physical unit. Suppliers need to connect the beneficiary, HCPCS item, first rental month, paid month number, and specific equipment record without treating the warehouse asset's age as the Medicare clock.
Which DME items are commonly capped rentals
CMS identifies wheelchairs and hospital beds as common capped-rental examples. Certain respiratory assist devices and other durable equipment can also fall into this payment class. Oxygen equipment follows a different payment framework and should not be treated as a 13-month capped rental.
The payment class depends on the item and current Medicare rules. Suppliers should verify the HCPCS code, fee-schedule category, coverage criteria, and any purchase option with their DME MAC instead of assuming that every reusable rental item follows the same clock.
What happens when use is interrupted
A hospital stay, temporary return, or other interruption does not automatically restart the 13-month period. When the beneficiary's medical need and use are interrupted for less than 60 consecutive days plus the days remaining in the last paid rental month, the period pauses and later resumes where it left off.
If the earlier medical need ends and the break continues for more than 60 consecutive days plus the remaining days in the last paid rental month, a new period may begin. CMS requires new documentation for that scenario, including a new prescription, new medical-necessity documentation, and an explanation of why the equipment was not medically necessary during the break. Suppliers should confirm the facts of an individual claim with their DME MAC.
What a DME supplier should track
For each capped-rental placement, keep the beneficiary and payer, HCPCS code, first rental month, rental anniversary date, month number billed and paid, interruption dates and reason, supporting documentation, ownership-transfer date, and the serialized unit assigned to the placement.
The operational record and billing record should agree. A supplier that cannot connect the paid rental month to the physical unit risks billing beyond the cap, missing required ownership transfer, or treating beneficiary-owned equipment as available warehouse inventory.
Capped Rental questions
What happens after 13 months of a Medicare capped rental?
After the 13th paid rental month, the beneficiary generally takes ownership of the capped-rental equipment. The supplier should record the ownership transfer and stop treating that unit as supplier-owned rental inventory.
Does a hospital stay restart the 13-month capped rental clock?
Not automatically. The result depends on whether the beneficiary's medical need continued, how long use was interrupted, and how many days remained in the last paid rental month. Shorter interruptions generally pause the period rather than restart it.
Is oxygen equipment a 13-month capped rental?
No. Medicare applies a separate payment framework to oxygen and oxygen equipment. Suppliers should not use the 13-month capped-rental timeline for oxygen equipment.
Which date starts the capped rental period?
The supplier should track the first covered rental month for the beneficiary and the item's rental anniversary date. Claim-specific timing and documentation questions should be confirmed with the supplier's DME MAC.
