Accrued Liabilities [Abstract]      
Payment advance $ 2,526    
Deferred revenue, description   The recoupment by CMS of our advance payment had been scheduled to begin 120 days after the date of receipt, at which time every claim we submit from that point would be automatically offset to repay the advance payment. Any unrecouped advance balance remaining after 90 days of the recoupment process was to be repaid such that 210 days after receiving the advance it would be entirely repaid. In October 2020, the Continuing Appropriations Act, 2021 and Other Extensions Act amended the repayment terms of the Advance Payment Program. The recoupment period was extended and the automatic recoupment began one year after the date the advance payment was received, which in our case meant recoupment started April 2021. Additionally, during the first 11 months after recoupment begins, the rate will be 25% and repayment will occur through an automatic recoupment of our Medicare payments. At the end of the 11 month period, the recoupment rate will increase. If the total amount of the advance payment is not recovered within 29 months from the date the advance was received, a demand letter for the outstanding balance will be issued. Since the Company has the right to repay the advance at any time, the entire balance is considered current.
