Date of Service

40.2 - Date of Service (Rev. 13147; Issued: 03-28-25; Effective: 01-01-25; Implementation: 03-25-25) For the codes that describe a weekly bundle (HCPCS codesG2067-G2069, G2073-G2077, and G0533) as well as HCPCS code G0137, one week is defined as 7 contiguous days. OTPs may choose to apply a standard billing cycle by setting a particular day of the week to begin all episodes of care. In this case, the date of service would be the first day of the OTP’s billing cycle. If a beneficiary starts treatment at the OTP on a day that is in the middle of the OTP’s standard weekly billing cycle, the OTP may still bill the applicable code for that episode of care provided that the threshold to bill for the code has been met. Alternatively, OTPs may choose to adopt weekly billing cycles that vary across patients. Under this approach, the initial date of service will depend upon the day of the week when the patient was first admitted to the program or when Medicare billing began. Therefore, under this approach of adopting weekly billing cycles that vary across patients, when a patient is beginning treatment or re-starting treatment after a break in treatment, the date of service would reflect the first day the patient was seen and the date of service for subsequent consecutive episodes of care would be the first day after the previous 7-day period ends. For the codes describing add-on services (HCPCS codes G2076-G2080, G0137, and G0534-G0536), the date of service should reflect the date that service was furnished; however, if the OTP has chosen to apply a standard weekly billing cycle, the date of service for codes describing add-on services may be the same as the first day in the weekly billing cycle.
