CMS Pub. 100-04, ch. 4, § 250.2.1
Billing and Payment in a Physician Scarcity Area (PSA)
Section 413a of the MMA 2003 requires that a new 5 percent bonus payment be
established for physicians in designated physician scarcity areas. The payment should be
made on a quarterly basis and placed on the quarterly report that is now being produced
for the HPSA bonus payments.
Section 1861(r)(1), of the Act, defines physicians as doctors of medicine or osteopathy.
Therefore, dentists, chiropractors, podiatrists, and optometrists are not eligible for the
physician scarcity bonus as either primary care or specialty physicians. Only the primary
care designations of general practice, family practice, internal medicine, and
obstetrics/gynecology, will be paid the bonus for the ZIP codes designated as primary
care scarcity areas. All physician provider specialties are eligible for the specialty
physician scarcity bonus except the following: oral surgery (dentist only); chiropractic;
optometry; and podiatry. The bonus is payable for dates of service January 1, 2005,
through December 31, 2007. The Medicare, Medicaid, and State Children’s Health
Insurance Program (SCHIP) Extension Act of 2007 amended §1833(u)(1) of the Social
Security Act and has extended payment of that bonus through June 30, 2008.
One of the following modifier(s) must accompany the HCPCS code to indicate type of
physician:
AG - Primary Physician
AF - Specialty Physician
Modifiers AG and AF are not required for dates of service on or after January 1, 2005.
Modifier AR, physician providing services in a physician scarcity area, may be required
for claims with dates of service on or after January 1, 2005 to receive the PSA bonus.
Refer to §250.2.2 of this chapter for more information on when modifier AR is required.
There may be situations when a CAH is not located in a bonus area but its outpatient
department is in a designated bonus area, or vice versa. If a CAH has an off-site
outpatient department/clinic the off-site department’s complete address, including the ZIP
code, must be placed on the claim as the service facility. The FISS must look at the
service facility ZIP code to determine if a bonus payment is due.
For electronic claims, the service facility address should be in the 2310E loop of the ASC
X12 837 institutional claim format. On the hard copy Form CMS-1450 the address
should be placed in “Remarks”; however, the ZIP code placement will be determined by
the A/B MAC (A).
