Additional Information on the Number of Trips
A provisional affirmative prior authorization decision may affirm a specified number of trips
within a specific amount of time. The prior authorization decision, justified by the beneficiary’s
condition, may affirm up to 40 round trips (which equates to 80 one-way trips) per prior
authorization request in a 60-day period. Alternatively, a provisional affirmative decision may
affirm less than 40 round trips in a 60-day period, or may affirm a request that seeks to provide a
specified number of transports (40 round trips or less) in less than a 60-day period. A
provisional affirmative decision could be for all or part of the requested number of trips.
Transports exceeding 40 round trips (or 80 one-way trips) in a 60-day period would require an
additional prior authorization request.
The MAC may consider an extended affirmation period for beneficiaries with a chronic
condition that is deemed not likely to improve over time. The prior authorization decision,
justified by the beneficiary’s chronic condition, may affirm up to 120 round trips (which equates
to 240 one-way trips) per prior authorization request in a 180-day period. The medical records
must clearly indicate that the condition is chronic, and the MAC must have established through
two previous prior authorization requests that the beneficiary’s medical condition has not
changed or has deteriorated from previous requests before allowing an extended affirmation
period.
