New Modifier for Rental Items

Original Effective Date: 12/06/2001
Revision Effective Date: 11/01/2013

Effective for dates of service on or after April 1, 2002, a new modifier has been established to indicate billing of durable medical equipment for a partial month of service.

  • KR - Rental Item - billing for partial month

The KR modifier is for use by suppliers who wish to exercise the option of billing Medicare for a partial month(s) of rental on DME. Although suppliers are entitled to bill and receive a full month's reimbursement for rented DME provided to qualifying beneficiaries, suppliers now have the option of billing for a partial month of service and receiving reimbursement on a prorated basis by using the KR modifier.

Suppliers who elect to bill for partial months should enter the date of service the rental period begins in the "From" field and the ending rental date of service in the "To" field of the HCFA-1500 claim form for each partial month of billing. The modifier "RR," indicating rental, and any other applicable modifiers must also be appended to the claim line for the partial month rental item(s).
