DME Medical Billing Modifiers – All You Need to Know

Durable medical equipment (DME) billing is a highly complicated process since it involves too many inclusions and a small detailing miss out may lead to rejection/denial of claims. In such additions, modifiers play an important role along with HCPCS codes according to the DME supplies. Modifiers provide the detailing/description of the DME item and decides the processing of claims raised on DME. Along with HCPCS code, DME medical billing also includes an ICD-10 diagnosis code that determines the medical condition for which the item has been prescribed.

Modifiers-a look

Not all HCPCS code requires a modifier to be added but most of it comes along with a modifier. Basically, a modifier conveys whether the item is new, used or rented on a capped basis, and when it comes to capped rentals, only modifiers show the difference of which month’s DME bill is being billed. Specifying these modifiers incorrectly can lead to rejection or denial of claims. Let us look at the commonly used modifiers in DME medical billing.

Common modifiers – RR for rental

NU for purchase of new equipment

UE for purchase of new equipment

Categories for using common modifiers

Use modifiers RR, NU and UE for the following categories:

  • Capped rental item
  • Oxygen equipment without contents
  • Items that require frequent and substantial servicing

When it comes to capped rentals, along with RR, the following modifiers should be added to determine the rental period:

KH- for initial claim and first-month rental

KI- for second and third-capped rental

KJ- from fourth to thirteenth capped rental months

Maintenance and servicing

MS is the modifier that is used for a 6-month maintenance and servicing fee for required parts and labour that are not covered under any warranty of the supplier or the manufacturer. Moreover, maintenance and service payments are made every six months only after the member initially owns the equipment.

Replacement and repair

RA is the DME code applicable for the replacement of a DME item due to loss, non-repairable damage, or theft. But this modifier should be used only for the first month rental claim for a replacement item.

RB is again a modifier that is applicable on replacement of a part of DME with respect to repairs if any.
