Radiation oncology planning

About 77321: Special teletherapy port planning

A special teletherapy port plan supports radiation treatment using nonstandard field arrangements, such as mantle or inverted-Y fields, when standard isodose planning categories do not fit.

A radiation oncologist and the radiation physics team use this planning service to develop a special external-beam treatment arrangement. It is associated with distinctive field designs such as mantle or inverted-Y fields, rather than routine teletherapy isodose plans. The planning work supports the prescribed treatment geometry and dose distribution in radiation oncology settings.

Report 77321 when the documented plan is a special teletherapy port plan, not merely because a conventional plan involves multiple fields or is technically demanding. The record should identify the treatment arrangement and support why this special plan category was used. CMS separately prices the professional and technical components: modifier 26 represents the professional interpretation, and modifier TC represents the technical work, equipment, and staff. Reporting without either modifier represents the global service.

77321 billing questions

When should 77321 be chosen instead of 77306 or 77307?

Use 77321 for a special teletherapy port arrangement, such as a mantle or inverted-Y field. Codes 77306 and 77307 describe simple or complex teletherapy isodose plans, respectively.

Does a plan qualify for 77321 just because it is complex?

No. The documentation should support a special port plan, rather than relying only on the number of fields or the general difficulty of planning.

How are the professional and technical components reported?

Modifier 26 identifies the professional component, and modifier TC identifies the technical component. Without either modifier, the claim represents the global service.

Can 77300 be reported with 77321?

A separately performed basic radiation dosimetry calculation may be reported with the plan when the record supports that distinct work.

What documentation supports 77321?

Document the special field arrangement and the planning work performed. The record should make clear why the service is a special port plan rather than a routine simple or complex isodose plan.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
