This report describes policies and practices for providing
chiropractic services to Medicare enrollees in seven managed care organizations
(MCOs). It was prepared in response to a request by Health Care Financing
Administration (HCFA) staff.
BACKGROUND
We recently completed an inspection on controls over
chiropractic services for Medicare and Medicaid beneficiaries (OEI-04-97-00490).
As part of that inspection, we surveyed the 10 largest Medicare MCOs from
10 different States.
Seven of the 10 MCOs responded to our survey and provided
information on their chiropractic policies and practices for Medicare
beneficiaries. However, the seven MCOs did not respond in time for us
to incorporate their data into our report on controls over chiropractic
services. Further, only four of the seven provided utilization data showing
the extent that they had provided chiropractic services for their Medicare
enrollees for 1995 and 1996.
Following issuance of the report on controls over chiropractic
services, HCFA staff requested that we provide them information on chiropractic
services in the seven MCOs that responded to our survey. The seven MCOs
represent a limited sample, and we do not present their policies and practices
for providing chiropractic services as being representative of all MCOs.
In order to project nationally, we would need to analyze a statistically
projectable random sample. The HCFA staff, however, said that a report
on the seven MCOs would enhance their understanding of MCO policies and
practices for providing chiropractic services. They were particularly
interested in comparing Medicare MCO and fee for service (FFS) utilization
data.
SCOPE AND METHODOLOGY
This report is based largely on data provided by the
seven MCOs that responded to our survey. We followed up survey responses
and interviewed officials at each MCO, by telephone, to clarify policies
and practices as appropriate. Four of the seven MCOs provided chiropractic
utilization data for 1995 and 1996. We compared this utilization data
to that for FFS organizations. We obtained FFS utilization data from HCFA's
Part B Extract and Summary System database and a 1 percent sample of HCFA's
National Claims History File. Additionally, we identified the number of
Medicare beneficiaries enrolled in FFS programs from HCFA's Data Compendiums.
UTILIZATION
In the four MCOs that provided utilization data, the
percentage of Medicare MCO beneficiaries who used chiropractic services
was low, as compared with Medicare FFS chiropractic utilization. For example,
in 1996, about 1.5 percent of Medicare MCO beneficiaries used chiropractic
services. In contrast, more than 4 percent of Medicare FFS beneficiaries
utilized chiropractic services during that same time period.
Utilization data presented by the four MCOs shoed that,
on average, Medicare MCO beneficiaries obtained slightly more chiropractic
treatments per year than did FFS Medicare beneficiaries. To illustrate,
Medicare MCO beneficiaries received almost 12 chiropractic treatments
per year for 1996, whereas Medicare FFS beneficiaries received almost
9 treatments.
The table below summarizes utilization data for the four
MCOs and Medicare FFS programs.

ACCESS
More Medicare beneficiaries used chiropractic services
when an MCO allowed direct access versus requiring a physician referral.
To illustrate, almost 2 percent of the beneficiaries with direct access
options used chiropractic services for 1995 and 1996. Conversely, less
than 0.5 percent of the beneficiaries with physician referral requirements
used chiropractic services during the same time period. Of the four MCOs
that provided chiropractic utilization data, two allowed direct access
and two required physician referrals.
Overall, the policies for accessing chiropractic services
varied among the seven MCOs that responded to our survey. Three MCOs allowed
direct access to chiropractic services, and the remaining four required
physician referral.
Policies also varied among the three MCOs that allowed
direct access to chiropractic service. Two of the three allowed an unlimited
number of treatments with appropriate medical documentation. The third
MCO limited direct access by beneficiaries to 12 treatments per year.
However, the MCO could authorize additional treatments.
Conversely, the four MCOs that required physician referral
had fairly consistent policies. To illustrate, all four allowed primary
care physicians (PCPs) to specify the number of chiropractic treatments
without prior authorization or review from the MCO.
COVERED SERVICES
All seven MCOs covered manual manipulation of the spine
to correct a subluxation, as required by HCFA. Additionally, one MCO expanded
its chiropractic benefit to include relief of axial skeletal muscle pain
when authorized by a PCP.
Six of the seven MCOs required X-rays to validate the
medical necessity of chiropractic services. The X-rays had to show subluxation
of the spine to justify chiropractic service. The six MCOs paid for the
X-rays. The remaining MCO did not require X-rays.
CO-PAYMENTS
Six MCOs required a co-payment to access chiropractic
services. The seventh MCO did not require a co-payment.
The co-payments required by six of the MCOs ranged from
$3-$15. Five of the six MCOs said their co-payment for chiropractic service
was the same as that for other types of services offered in their plans.
The sixth MCO said its co-payment for chiropractic service was lower than
what it required for other types of services.
POST-PAYMENT REVIEWS
Five of the seven MCOs conducted utilization or post-payment
reviews. Some of the items reviewed were chiropractic billing, corroboration
of medical necessity, patient satisfaction, communication between chiropractors
and PCPs, and number of chiropractic visits per year. Based on such reviews,
one of the five MCOs had denied payment to chiropractors. ANother MCO
had referred 48 chiropractors to the FBI for investigation of fraudulent
activities. At the time we prepared this report, the 48 chiropractors
were still under investigation. None of the other MCOs had referred chiropractors
for investigation.
We hope that you find this information responsive to
your request. Please do not hesitate to call me or George Grob, Deputy
Inspector General for Evaluation and Inspections, or have your staff call
Mary Beth Clarke at (202) 619-2481 with any comments or questions you
wish to share.
