This document corrects technical errors that appeared in the final notice that was published in the Federal Register on April 21, 1987 (52 FR 13176) on additions and revisions to the current list of surgical procedures for ambulatory surgical centers (ASCs).
This final notice announces additions and deletions to the current list of surgical procedures for which facility services are covered when the procedures are performed in an ambulatory surgical center (ASC). We are adding one procedure and deleting 48 procedures. The changes contained in this final notice result from our consideration of the public comments received in response to a proposed notice published on August 11, 1987 and from analysis of more recent data and subsequent consultation with medical organizations and professional societies. This notice implements section 1833(i)(1) of the Social Security Act, as amended by section 9343 of the Omnibus Budget Reconciliation Act of 1986 that requires, in part, that the list of covered ASC procedures be reviewed and updated every 2 years.
This final notice announces additions and revisions to the current list of surgical procedures for which facility services are covered when the procedures are performed in an ambulatory surgical center. Our current list of covered ASC procedures was published in the Federal Register on August 5, 1982 (47 FR 34099). The changes contained in this final notice result from our consideration of the public comments received in response to a proposed notice published on February 16, 1984 (49 FR 6023), which requested additions or revisions to the current list of ASC procedures and charge schedules for the new procedures, and subsequent consultation which medical organizations.
This final rule sets forth the methodology that will be used to determine payments for hospital outpatient services furnished to Medicare beneficiaries in connection with ambulatory surgical procedures. This rule implements section 9343(a) of the Omnibus budget Reconciliation Act of 1986.
A new ambulatory procedure for treatment of female urinary incontinence (intravaginal slingplasty, IVS) was performed on 50 patients. In all patients the surgical procedure was carried out under local anaesthesia and without postoperative urinary catheterization. The technique has been elaborated from previous experimental and clinical studies and aims at restoration of the pubourethral ligament and the suburethral vaginal hammock. Thirty-eight patients suffered from genuine stress incontinence as objectively verified and 12 patients had symptoms and signs of both urge and stress incontinence. Thirty-nine (78%) patients were completely cured from their stress incontinence symptoms. Another six patients (12%) reported a considerable improvement of their urinary incontinence leaking only occasionally. Concerning urge incontinence symptoms a significant relief of the symptoms was obtained in 6 of 12 patients. No intra- or post-operative complications occurred.
This final notice with comment period implements section 1833(i)(1) of the Social Security Act, which requires, in part, that the list of covered ambulatory surgical center (ASC) procedures be reviewed and updated at least every 2 years. This notice announces the specific additions to and deletions from the list of surgical procedures for which facility services are covered when the procedures are performed in a Medicare-participating ASC, as well as the assigned payment groups for each addition. The notice also announces a change in our criteria for deleting procedures from the ASC list. This notice also responds to public comments received in response to our proposed notice published December 14, 1993 (58 FR 65357). In that notice, we requested comments on the proposed additions to and deletions from the list of covered surgical procedures for ASCs; the proposed quantitative change in our deletion criteria; the development of alternatives to the proposed quantitative deletion criteria; and the assignment of payment groups for each addition. Finally, this notice solicits public comment on certain additions to and deletions from the ASC list that had not been suggested in our December 1993 proposed notice. It also solicits public comment on the assignment of payment groups for certain new procedure codes.

OBJECTIVE: To determine whether prophylactic intravenous administration of caffeine, to daily caffeine users, decreases the frequency of postoperative headache and shortens recovery time. DESIGN: The study was a prospective, randomized, double-blind investigation with predetermined sample size and statistical power. MATERIAL AND METHODS: After Mayo Institutional Review Board approval and informed consent were obtained, 300 adult ambulatory surgical patients were enrolled in this study, which included randomization to receive either placebo or caffeine (200 mg intravenously) in the postanesthesia care unit. While recuperating, patients were allowed their choice of postoperative beverages. Before dismissal, patients completed a questionnaire providing details about intake of caffeine and tobacco, history of headache, and demographic data. Patients were considered "at risk" for symptoms of caffeine withdrawal if they did not drink a caffeinated beverage after the surgical procedure. RESULTS: Completed questionnaires were obtained from 234 patients. Patients at risk for symptoms of caffeine withdrawal were less likely to have a postoperative headache if they received caffeine intravenously rather than placebo-10% versus 23% (P < 0.05). Time until recovery was not significantly different between caffeine and placebo study groups. CONCLUSION: We conclude that prophylactic intravenous administration of caffeine was beneficial for those patients at risk for symptoms of caffeine withdrawal. For patients who consume caffeinated beverages on a daily basis, we recommend prophylactic administration of caffeine on the day of an ambulatory surgical procedure and anesthesia.
In this rule we propose to--Update the criteria for determining which surgical procedures can be appropriately and safely performed in an ambulatory surgical center (ASC); Make additions to and deletions from the current list of Medicare covered ASC procedures based on the revised criteria; Rebase the ASC payment rates using cost, charge, and utilization data collected by a 1994 survey of ASCs; Refine the ratesetting methodology that was implemented by a final notice published on February 8, 1990 in the Federal Register; Require that ASC payment, coverage, and wage index updates be implemented annually on January 1 rather than having these updates occur randomly throughout the year; Reduce regulatory burden; and Make several technical policy changes. This proposed rule implements requirements of section 1833(i)(1) and (2) of the Social Security Act.

The aim of this study was to determine the need for supplemental oxygen during recovery from general anesthesia for ambulatory surgery in healthy women without obesity or respiratory disease. Arterial oxygen saturation by pulse oximetry (SpO2) was monitored throughout the first postoperative hour in 164 patients. The patients breathed room air during recovery. Supplemental oxygen was given only to those who became hypoxemic (SpO2 less than or equal to 92%). It was discontinued at the end of 15 minutes and reinstituted for another 15 minutes if hypoxemia recurred. Twelve patients (7%) became hypoxemic and required supplemental oxygen for various periods of time up to 105 minutes. The need for supplemental oxygen increased with increasing age (P less than 0.05) but was not associated with a history of cigarette smoking, tracheal intubation, amount of opioids or sedatives given intraoperatively, anesthetic duration, or level of consciousness during recovery. Hypoxemia was neither predictable nor clinically apparent. We recommend that, unless arterial oxygenation is monitored, ambulatory patients should routinely receive supplemental oxygen during recovery from general anesthesia.
We report a rare coronary anomaly in a 3-month old symptomless infant with an anomalous origin of the left coronary artery, that became manifest during anaesthesia for an ambulatory procedure, leading to circulatory arrest. Precordial stethoscope and pulse oximeter unequivocally showed a circulatory arrest. Even in ambulatory procedures, a presumed healthy patient may quickly develop a life-threatening condition because of occult disease. The successful management of such cases depends on efficient and coordinated teamwork.
The object was to study prospectively the results of a modified intravaginal slingplasty for the surgical treatment of female stress incontinence, carried out under local anesthesia as a day procedure. Seventy five patients with genuine stress incontinence were operated upon and followed for a 2-year period. All patients were diagnosed urodynamically to have genuine stress incontinence. Pad tests and quality of life assessments were carried out in all patients both pre- and postoperatively. There were no intra- or postoperative complications and 63 patients (84%) were completely cured throughout the 2-year follow-up period. Six patients (8%) were significantly improved, i.e. they did not loose urine apart from an occasional leakage during severe cold etc. In the remaining 6 patients (8%) no improvement was seen. These failures were obvious at the first postoperative check-up after 2 months. Thus, there were no relapses after 2 months. All but 5 patients were able to void properly directly after surgery. These 5 needed an indwelling catheter during the night directly after the operation. All 75 patients were released from the hospital the same day or the day after surgery without catheterization. Mean sick leave was 10 days and mean operation time 22 minutes. No defect healing or rejection of the sling occurred. It is concluded that the procedure described is a promising new technique for the surgical treatment of female stress incontinence. Prospective long-term studies including more patients are in progress to establish the definitive place of this technique in the clinical routine.
OBJECTIVE: To test the hypotheses that (1) for-profit (FP) and not-for-profit (NFP) hospitals are less likely than public hospitals to admit cases reimbursed by prospective payment favoring ambulatory over inpatient care; (2) admission odds of public, FP and NFP hospitals will converge under increasing hospital competition. METHODS: Retrospective, population-based, cross-sectional study covering 29,699 cases of unilateral, femoral/inguinal hernia operation (major surgical procedure) and 60,626 cases of cataract surgery (local surgical procedure), from Taiwan's National Health Insurance database was used. Diagnosis-wise logistic regression analysis were done to examine associations between admission propensities of FP versus public and NFP hospitals (large teaching hospitals with > or = 250 beds versus district hospitals with < 250 beds) under high and low competition, adjusted for clinical complications, and patient as well as physician demographics. RESULTS: Large public teaching hospitals are significantly more likely than FP district hospitals to admit hernia patients (ORs = 1.9 and 2.6, respectively, under high and low competition), and cataract surgery patients (ORs = 5.0 and 5.4, respectively, under high and low competition). The corresponding odds ratios for public district hospitals (relative to FP district hospitals) are 1.2 and 3.9 for hernia and 4.9 and 2.7 for cataract surgery. Odds ratios show convergence of admission odds across hospital ownership under high competition relative to low competition for hernia (OR range for different hospital types under high competition, 1.0-1.9; and under low competition, 1.0-3.9). Cataract cases show high divergence of admission odds between public and FP/NFP hospitals regardless of competition level (OR range for different hospital types under high competition, 0.3-5.0; and under low competition, 0.3-5.4). CONCLUSION: Overall, our data support the study hypotheses. Differences in the relevance of inpatient care for hernia and cataract surgery may account for the lack of admission convergence of public hospitals and FPs under high competition among cataract surgery group.
Adequate postoperative analgesia without side effects is necessary to facilitate same-day discharge of ambulatory patients after ambulatory surgery. This study compared the use of intravenous morphine and fentanyl after painful ambulatory procedures with respect to analgesic efficacy, the incidence of side effects, and impact on the patient's readiness for discharge. Fifty-eight patients undergoing ambulatory surgery were prospectively randomized to receive morphine or fentanyl for postoperative analgesia and studied in double-blind fashion. The drugs were administered in equipotent doses in the postanesthesia care unit (PACU) and were titrated against pain scores until a visual analog score < 40 mm was achieved and the patient was satisfied with the level of analgesia. In the ambulatory surgical unit, oral analgesia was available. Pain scores, amount of analgesia used, the incidence of side-effects (nausea and vomiting, sedation and dizziness), the times to achieve recovery milestones, and fitness for discharge were studied. Equal amounts of morphine and fentanyl were used in the PACU, but pain scores were higher in the fentanyl group in the ambulatory surgical unit. In addition, the fentanyl group required more oral analgesia than the morphine group (69% vs 17%; P < 0.0002). The incidence of in-hospital side effects was similar. However, the morphine group had a more frequent incidence of postdischarge nausea and vomiting than the fentanyl group (59% vs 24%; P < 0.016). There was no significant difference in the duration of stay in the PACU (morphine vs fentanyl, 69 +/- 15 min vs 71 +/- 20 min), the times to achieve recovery milestones, and fitness for discharge (morphine vs fentanyl, 136 +/- 41 min vs 132 +/- 40 min). The short duration of fentanyl was not associated with faster discharge times; most patients required additional analgesia to control pain. Morphine produced a better quality of analgesia but was associated with an increased incidence of nausea and vomiting, the majority of which occurred after discharge.
Under the proposed rules published elsewhere in this issue of the Federal Register, reimbursement would be available under the Medicare Supplementary Insurance program (Part B) for independent ambulatory surgical center (ASC) facility services in connection with certain surgical procedures. For those same procedures, physicians would be reimbursed at 100 percent of their reasonable charges for providing services in connection with the procedure performed in a participating ASC, on an outpatient basis in a hospital or in a hospital-affiliated ambulatory surgical center (HAASC) if certain requirements are met. This notice contains the proposed list of the surgical procedures pertinent to these reimbursement provisions.
Under the final rules published elsewhere in this issue of the Federal Register, reimbursement will be available under Part B of Medicare for ambulatory surgical center (ASC) facility services in connection with certain surgical procedures. For those same procedures, physicians will receive 100 percent reimbursement for providing services in connection with the procedure performed on an ambulatory basis if certain requirements are met. This notice contains the initial list of the surgical procedures pertinent to these reimbursement provisions. Additional procedures will be added and published in the Federal Register, when appropriate.
