Because the resolution of claims that are part of Medicare audit programs can take in excess of three 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.
