Our intent in establishing this criterion was to ensure that tests that meet the definitions in this provision are not directly related to the care provided in the hospital, and we believe the modification we are finalizing meets that intent more clearly than our original proposal.",

One commenter indicated strong support because these coding changes will help bring transparency to the services provided in ( printed page 69825) those settings. These commenters believe that under current coding and billing conventions, “home” services are all lumped together and thus difficult to untangle and analyze productively.",

+ "WHNGCYHB:3310": "Response: To streamline the process, we proposed to have a single process with a single audit step, regardless of the reason an ACO is selected for the audit. The proposals were intended to streamline the audit process, provide audit feedback to ACOs and validate the accuracy of quality data in a timely manner that, in turn, permits timely feedback and allows accurate information to be used in the reconciliation of the ACO's performance for the prior year. Incorporating an appeals process would severely delay ACO reconciliation, and therefore, we do not agree that such a process should be included. Additionally, we believe that establishing an appeals process would be inconsistent with the statutory preclusion on administrative and judicial review of the assessment of the quality of care furnished by the ACO under section 1899(g) of the Act. Nevertheless, we are sympathetic to comments noting that simple mistakes can be made when reporting quality that, if given the opportunity to be rectified, would not reflect poorly on the actual quality of the care delivered by the ACO. We note, however, that the CMS web interface provides a number of reports that ACOs can access and use to check their data entry in the CMS Web Interface to assist ACOs in monitoring the accuracy of the quality data they submit. These reports can help ACOs to identify and correct errors in their data submission during the timeframe the CMS Web Interface is open for quality data submission. Even so, we believe there may be instances following an audit when CMS may need to employ some discretion related to the adjustment of an ACO's overall quality score. For example, an ACO may have experienced an error when reporting measures electronically (for example, an error in mapping the extensible markup language (XML) specifications) that affects all beneficiaries reported on for a quality measure. In this instance, a mapping error could be out of the control of the ACO that, based on an audit, demonstrated that it had otherwise fulfilled our quality reporting requirements. In the absence of flexibility not to apply an adjustment to the ACO's overall quality score, such an ACO may be unfairly penalized. Therefore, we are modifying our proposed policy. Specifically, we are finalizing a policy under which CMS will adjust an ACO's overall performance score to reflect audit findings when the ACO has an audit mismatch rate of greater than 10 percent. However, we will retain discretion not to apply this adjustment to the ACO's score in certain unusual circumstances where it would be inappropriate to apply the adjustment. We note that we do not intend to employ this discretion to avoid adjusting an ACO's overall performance score in instances when the ACO cannot produce adequate validation of the data submitted or did not interpret the measure specifications correctly. For example, if we determine that the ACO has not produced medical record information sufficient to validate the data the ACO submitted to the web interface, we would not exercise our discretion not to apply the adjustment to the ACO's overall performance score based on results of the audit. We believe it is reasonable to: (1) Hold ACOs accountable for the accuracy of the data submitted according to information they validate from medical record reviews; and (2) require ACOs to produce proof of such accuracy in the event of an audit. Also, if we determine that the ACO did not interpret the measure specifications correctly, we would apply the adjustment to the ACO's overall performance based on audit results because ACOs are provided numerous opportunities to receive assistance from CMS before and during the quality measure submission process. For example, ACOs may access measure specification documents that are available on our Web site, contact the dedicated help desk, and attend webinars that we hold to educate ACOs about measure specifications and reporting requirements. Therefore, we believe that this modification of our proposal addresses stakeholder ( printed page 80492) concerns while permitting us to perform timely quality validation audits that hold ACOs accountable not only for the quality of the care they provide but also for the accuracy of their quality reporting.",
