HCPCS and CPT Standard Modifiers
HCPCS and CPT Standard Modifiers
In preparation for the implementation of the Health Insurance Portability and
Accountability Act (HIPAA), it is essential that you use standard CPT and HCPCS
modifiers to describe the service for which you are billing. Modifiers indicate that a
service or procedure you've performed has been altered by some specific circumstance,
but has not changed in its definition or code.
To prepare for HIPAA's new electronic claims transaction format, we will require
standard modifiers on all claims (paper and electronic) that are received on or after June
1, 2003, and will reject claims that use non-standard modifiers after that date. If
you use a billing vendor, please contact them to be sure that they make the
appropriate changes to begin processing your claims using standard modifiers.
We¡¯ve included a table of standard CPT and HCPCS modifiers here for your
convenience. Ambulance origin and destination modifiers, used with transportation
service codes, are included in a separate table at the end of this document.
Please refer to Fax-on-Demand document 834 for specific BCBSMA processing
guidelines for CPT modifiers, or to the CPT and HCPCS manuals for a complete list of
standard modifiers. You can order these manuals on-line:
