KB and 99 Modifiers

KB and 99 Modifiers-More than Four Modifiers

KB Beneficiary requested upgrade for ABN, more than four modifiers identified on claim.
99 Modifier overflow.

The KB modifier only applies to beneficiary upgraded claims for DMEPOS where the supplier obtained an ABN and there are more than four modifiers on the claim line. The 99 modifier is used in any other situation when a claim line has more than four modifiers.

When a supplier uses more than four modifiers, the KB or 99 must be added as the fourth modifier to the HCPCS code. On paper claims, the remainder of the modifiers must be listed in Item 19 with an indicator as to which line they apply to. On electronic claims, the remainder should be entered in the NTE segment, the 2400 loop.

These are not all inclusive lists.
