These checkpoints summarize published CMS guidance for radiation oncology claims. The payer’s policy and the rule in effect for the date of service always apply.
A weekly unit of radiation treatment management equals five fractions or treatment sessions, regardless of the actual time period in which services are furnished.
Billing entities must indicate on each claim the number of fractions for which payment is sought under weekly treatment management.
The radiation therapist does not have to personally examine the patient at each fraction for the weekly treatment management code to be payable.
Multiple treatment delivery sessions on the same day are payable only if there is a distinct break in therapy and the sessions are usually furnished on different days.
A skilled nursing facility may not bill weekly treatment management for its outpatients and should instead bill radiation treatment delivery codes.
Where technical component payments are made, Medicare pays separately for the expendable source in most brachytherapy procedures, except remote after-loading high intensity procedures.
