During 2013, CMS announced additional delays in the adjudication process of claims that are part of Medicare audit programs. Because the resolution of such claims can take in excess of two years, we review the patient receivables that are part of this adjudication process to determine their appropriate classification as either current or noncurrent. Amounts considered noncurrent are included in Other long-term assets in our consolidated balance sheet.

At December 31, 2013 and 2012, our allowance for doubtful accounts represented approximately 11.1% and 11.0%, respectively, of the total patient due accounts receivable balance.

The following is the activity related to our allowance for doubtful accounts (in millions):
