What 77436 covers

This service covers planning for superficial radiation therapy, used when radiation is directed at a target near the body surface. A radiation oncologist typically determines the treatment approach for the target; the planning work may involve the radiation oncology team in an outpatient cancer center. It is distinct from delivering a treatment fraction or providing treatment management during a course of radiation.

Report the planning service when the record supports a plan for superficial radiation treatment, with documentation identifying the target and the planned approach. CMS recognizes separately priced professional and technical components: modifier 26 identifies the interpretation, and modifier TC identifies the equipment and staff portion. Without either modifier, the claim represents the global service.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

77436 billing questions

How is this different from codes 77437 and 77438?

Code 77436 is for planning. Codes 77437 and 77438 describe superficial radiation treatment delivery, distinguished by the treatment energy.

Can the professional and technical portions be billed separately?

Yes. CMS lists modifier 26 for the professional interpretation and modifier TC for the technical portion involving equipment and staff. Without a modifier, the service is billed globally.

What documentation supports reporting 77436?

The record should identify the superficial treatment target and document the treatment approach developed for it.

Is 77439 the same service as this planning code?

No. Code 77439 is for ultrasound image guidance associated with superficial radiation treatment delivery; 77436 represents planning.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
