Claims Coding Requirements
90.4.3 - Claims Coding Requirements
(Rev. 608, Issued: 07-22-05; Effective: 01-01-06; Implementation: 01-03-06)
For services with dates of service prior to January 1, 2005, physicians must indicate that their
services were provided in an incentive-eligible rural or urban HPSA by using one of the
following modifiers:
QB - physician providing a service in a rural HPSA; or
QU - physician providing a service in an urban HPSA.
Effective for claims with dates of service on or after January 1, 2006, the QB and QU
modifiers will no longer be accepted. Claims with prior dates of service must still be submitted
with those modifiers. The AQ modifier, Physician providing a service in a Health Professional
Shortage Area (HPSA), will replace the QB and QU modifiers and will be effective for claims
with dates of service on or after January 1, 2006.
For services with dates of service on or after January 1, 2005, the bonus will automatically be
paid without the submission of a modifier for the following:
•
When services are provided in a zip code area that fully falls within a full county
HPSA;
•
When services are provided in a zip code area that partially falls within a full county
HPSA and has been determined to be dominant for the county by the USPS; and
•
When services are provided within a zip code that fully falls within a partial county
HPSA.
The submission of the QB or QU modifier, or the AQ modifier for claims with dates of service
on or after January 1, 2006, will be required for the following:
•
When services are provided in zip code areas that do not fully fall within a designated
full county HPSA bonus area;
•
When services are provided in a zip code area that partially falls within a full county
HPSA but is not considered to be in that county based on the dominance decision
made by the USPS;
•
When services are provided in a zip code area that partially falls within a partial
county HPSA; and.
•
When services are provided in a zip code area that was not included in the automated
file based on the date of the data run used to create the file.
In order to be considered for the bonus payment, the name, address, and zip code of where the
service was rendered must be included on all electronic and paper claims submissions.
