WASHINGTON REPORT

HCFA Issues Proposed Rule on Expenses, "-25" Modifier and Discontinuous Time

Michael Scott, Director
Governmental and Legal Affairs


On July 22, the Health Care Financing Administration (HCFA) issued a proposed rule setting forth several changes in payment policy under the Medicare Fee Schedule (MFS) for calendar year 2000. Those portions of the rule of direct interest to ASA members deal with implementation of resource-based values under the MFS for malpractice insurance costs, refinement of resource-based practice expense values first implemented last January 1, use of the CPT modifier "-25" and proper calculation of discontinuous anesthesia time. Of particular concern is HCFA's estimate that reimbursement to anesthesiologists will progressively decline by 8 percent between 2000 and 2001, based upon its proposed practice expense refinements.

Malpractice Expense

When the MFS was placed into effect in 1992, allowances for malpractice insurance costs were not derived from actual malpractice premium data, but rather were calculated from existing charge-based data. The terms of the Balanced Budget Act of 1997 (BBA) required HCFA to develop resource-based allowances for use beginning in calendar year 2000, and the proposed rule responds to that requirement. HCFA's proposed allowances are based on a three-step process under which a national average premium for each specialty is calculated, a risk factor for each specialty is factored in and then malpractice RVUs for each code are calculated (in the case of anesthesia codes, malpractice cost is calculated as a percentage of the anesthesia conversion factor).

Based upon national average premiums for the period 1990-95, during which the anesthesiology average premium dropped by an annual average of 6.5 percent, HCFA calculates that after making the necessary adjustments to achieve budget neutrality, implementation of the resource-based malpractice expense values will negatively impact anesthesiology reimbursement by 0.1 percent. At the same time, HCFA notes its intention to collect more recent premium data, a step that could conceivably modestly affect HCFA's proposed change for the specialty.

Practice Expenses

As in the case of malpractice insurance expenses, physicians' other practice expenses accounted for under the MFS were originally derived from charge-based data. In 1994, however, Congress directed HCFA to develop resource-based practice expense data and to place these values into effect beginning in 1998. Under the terms of the BBA, the effective date was delayed to January 1, 1999, with the new resource-based values to be phased in over a three-year period and become fully effective January 1, 2002. Over this period, HCFA was required to engage in a process of continuous refinement of the practice expense values.

HCFA's practice expense values for 1999 were derived from the AMA's Socioeconomic Monitoring System (SMS) survey data on physician practices in various specialties as well as from information on direct expenses developed by several Clinical Practice Expense Panels (CPEPs) previously appointed by HCFA. Using the so-called "top down" method of determining expenses associated with each procedure, HCFA essentially assumed that the SMS data provided a reasonably accurate method of allocating relative resource costs among the specialties, and that the allocation of direct costs to specific procedures within the specialty could be accomplished based upon the CPEP data.

Included in the practice expense calculations for 1999 are certain CPEP-developed expenses for the use of physician-employed clinical personnel to provide care for hospital patients. Of specific interest to the specialty, the CPEP anesthesiology panel had included inputs of up to 195 minutes of clinical staff time per procedure in a facility setting, divided among a registered nurse, a physician assistant and an anesthesia technician. In the July 22 proposed rule, HCFA now proposes to disallow these expenses, either on the grounds that Medicare already pays for such personnel through Part A, that use of such personnel is not typical or that a literal reading of the law does not allow these expenses to be included.

As noted, HCFA estimates that elimination of these direct costs will result in an 8-percent decline in reimbursement to anesthesiologists under Medicare. Since practice expenses currently represent about 21.5 percent of total reimbursement for anesthesiology services, the proposed cut will, when fully phased in, apparently reduce currently allowed anesthesiology practice expenses by about 37 percent overall.

HCFA expressly states in the proposed rule that because it cannot specifically identify these disallowed direct costs in the SMS data, it is not adjusting the SMS allocations among specialties. If this is so, then the only explanation for the decline in reimbursement is that disallowed practice expenses are being shifted from anesthesia codes to other procedures performed by anesthesiologists such as evaluation and management (E&M) and pain management codes, which are also performed by other specialists. As of this writing, ASA has not been able to verify the accuracy of this conclusion, and HCFA personnel have not been able to provide clarifying data.

ASA intends, in its comments on the proposed rule, to challenge the propriety of HCFA's action. Recent survey data available to ASA confirms the fact that many anesthesiology practices do employ clinical personnel, not otherwise paid for by HCFA, to assist in the provision of anesthesiology services. ASA will be working with its consultant, Compass Health Analytics of Boston, both to examine HCFA's methodology and to attempt to buttress its argument for appropriate recognition of clinical assistance expenses.

Use of the CPT Modifier "-25"

AMA CPT-4 contains a modifier "-25" to identify a "significant, separately identifiable evaluation and management service by the same physician on the same day of the procedure or other service." HCFA has recognized the appropriateness of the modifier for some time and, if the modifier is used, has allowed payment for such an E&M service "above and beyond the preoperative and postoperative work of the procedure" provided on the day of a global surgery. HCFA's proposed rule adds the clarification that for procedures where the global surgery rules do not apply, a provider may only bill for a separately identifiable E&M service by using the "-25" modifier. According to HCFA, requiring use of the modifier will assist carriers in claims adjudication, eliminate unnecessary denials and alert physicians to the need for documentation in the medical record to support additional payment.

Discontinuous Anesthesia Time

Responding to pressure from ASA, HCFA's proposed rule also contains specific instruction on billing for anesthesia time when that time is discontinuous, that is, when for some reason there is a break in the continuous presence of the anesthesia provider. Although accounting for this time has not been a problem with most Medicare carriers, a few have simply refused to develop a policy on the issue, thus making HCFA's intervention desirable.

Under the MFS, anesthesia services are paid on the basis of base (complexity) units and by the use of 15-minute time units counting from preparation of the patient for anesthesia care and ending when the patient may be safely placed under postoperative care. In this continuum, however, there may be periods when a patient can be safely observed by nonanesthesia personnel, as between the time a patient receives regional anesthesia and is moved to the operating room, or between the time the patient is being prepared for induction and anesthesia is actually induced.

HCFA proposes to revise its current reimbursement regulations to provide that "In counting anesthesia time, the anesthesia practitioner can add blocks of anesthesia time around an interruption in anesthesia time as long as the anesthesia practitioner is furnishing continuous anesthesia care within the time periods around the interruption." The agency cautions, however, that this addition should not be interpreted as meaning that it now will pay for time units for the pre-anesthesia examination and evaluation, services for which payment is included in the anesthesia base units.

House Begins Month-Long Recess Without Action on Managed Care

With chances for a compromise on patient protection appearing increasingly dim, House Speaker Dennis Hastert (R-IL) determined not to schedule floor debate on competing managed care bills prior to the August recess. The legislative impasse was formed by the breakdown in discussions between Thomas J. Bliley, Jr., (R-VA) and John D. Dingell (D-MI), Chairman and Ranking Minority Member, respectively, of the House Commerce Committee, and rejection by moderate Republicans of a leadership attempt to fashion a bill drawn largely from the weak bill passed by the Senate in July. Immediately prior to recess, however, Congressman Charlie Norwood (R-GA) and Congressman Dingell introduced the Bipartisan Consensus Managed Care Improvement Act (H.R. 2723), which by the time of this writing had attracted 21 Republican co-sponsors -- more than enough, when combined with the Democrats, to assure passage of the bill. At the same time, however, Congressmen Tom Coburn (R-OK) and John Shadegg (R-AZ) announced development of their own GOP "compromise" bill and sought endorsements from the medical community. No one is certain which bill, if any, will actually be brought to the House floor after the recess.
