The Centers for Medicare & Medicaid Services has instructed its contractors to hold claims containing services paid under the Medicare physician fee schedule for the first 10 business days of June.

Congressional leaders are trying to avert a 21 percent payment cut scheduled to take effect June 1 under the current fee schedule.

The 10-day hold applies to claims with dates of service of June 1 and later. According to CMS officials, the hold should have little impact on provider cash flow because electronic claims are not paid until at least 14 calendar days after receipt.
