FARGO, N.D.--Noridian Administrative has issued instructions for resubmission of oxygen claims “for subsequent months if [providers] have received payment for the initial replacement month (the claim with the RA or RP modifier).”
 
According to an update from the Jurisdiction D DME MAC, some providers have received non-covered denials with the N370 message (billing exceeds the rental months covered/approved by the payer). This happened “because the claim with the RA or RP modifier had not yet been worked by our claims staff and the new CMN for the replacement equipment was not yet loaded into the claims processing system,” NAS said.
 
Claims that should be resubmitted are claims with dates of service Jan. 17 through March 31, 2009.
 
The MAC’s message also noted providers may have been previously instructed that these subsequent rental claims would be “mass adjusted” by NAS and no further action would be needed. “Our plan was to do these mass adjustments but after further review we have determined that the most expeditious way to handle these claim denials is to ask suppliers to resubmit,” the update said, adding these reminders about replacement oxygen claims:
 
—Only the initial oxygen claim requires a modifier RP, prior to Jan. 1, 2009, or modifier RA, effective Jan. 1, 2009, and after, when replacing oxygen equipment.
 
—Subsequent oxygen rental claims, those billed after the initial month of replacement, should not include the RP or RA modifier.
