Timeframe Between Initial & Subsequent Annual Wellness Visits
Annual Wellness Visits (AWVs) are covered by Medicare at 12 month intervals. This means that 11 full calendar months must pass after the month in which a beneficiary had received an AWV.
Under this method of counting, a beneficiary could receive an AWV at the end of a given month, for example, January 2011, then in the following January 2012, the beneficiary would be eligible for an AWV in the beginning of that month. Therefore 365 days would not need to elapse between visits, provided that 11 full months had passed since the last visit.
