DME clinical edits
Several DME, PO and supplies HCPCS codes require the use of modifiers to identify that anatomical, laterality, functional or support policy criteria is met. Claims reported without the required modifiers will be denied. Those reported with modifiers that do not support medical necessity may be denied to member liability. Please note that this does not replace the need for NU, RR, UE, etc. associated with DME items.
Capped Rental Modifiers
Reminder – Capped rentals have to include RR modifier to identify capped rental along with modifiers to identify the period of capped rental with modifiers KH, KI, or KS
- KH (DMEPOS item, initial claim, first month rental) is only to be used for the initial claim of the capped rental period
- KI (DMEPOS item, second- or third-month rental) is only to be used for the second and third months of the capped rental period
- KJ (DMEPOS item, parenteral enteral nutrition (PEN) pump or capped rental, months 4 to 15) is only to be used for the fourth through final month of the capped rental period
Functional Modifiers K0-K4
Functional Modifiers have been developed to define ability (DME Medical Review Policy). When a lower limb prosthesis is billed without one of the functional modifiers, the prosthesis will be denied.
- Modifier K0 indicates the prosthesis does not enhance the member’s quality of life or mobility and medical policy (or for Medicare, LCD) will drive coverage when modifier is appended.
- Modifier K1 identifies the prosthesis creates a functional level of 1 (see HCPCS for modifier definition)
- Modifier K2 identifies the prosthesis creates a functional level of 2 (see HCPCS for modifier definition)
- Modifier K3 identifies the prosthesis creates a functional level of 2 (see HCPCS for modifier definition)
