Radiation therapy uses Current Procedural Terminology (CPT) codes like 77427, 77431, 77432, 77435, 77469, and 77470 for treatment management, as defined by the American Medical Association.
What are the CPT codes for IMRT?
IMRT (Intensity-Modulated Radiation Therapy) uses CPT codes including 77301 for the plan and 77014, 77280, 77285, 77290, 77295, and others for delivery and guidance, according to CMS guidelines.
Billing these codes covers image guidance, planning, and delivery of IMRT. In outpatient settings, hospitals get bundled payments under OPPS, so codes like 77301 may already be wrapped into APC payments.
What is g6012 CPT?
CPT code G6012 describes radiation treatment delivery to 3 or more separate treatment areas using custom blocking, tangential ports, wedges, rotational beam, compensators, or electron beam at 6–10 MeV, per the AMA’s CPT Assistant.
This HCPCS Level II code handles complex radiation delivery with multiple fields and customization to spare healthy tissue.
How often can 77301 be billed?
CPT code 77301 may be billed just once per patient’s entire treatment course, as per Medicare’s National Correct Coding Initiative (NCCI) edits.
Billing multiple planning codes like 77301, 77295, and 77306–77307 on the same day for the same treatment volume? That’s a no-go and will get denied.
How often can 77263 be billed?
CPT code 77263 can only be billed once per treatment course, according to AMA CPT guidelines.
This code covers 3D radiotherapy plan prep—don’t try to use it more than once for the same regimen.
What is CPT G6002?
CPT code G6002 represents stereoscopic x-ray guidance for localization of the radiation therapy target volume, as defined in the HCPCS Level II code set.
You’ll see this most often during setup to nail down accurate radiation delivery, especially in stereotactic treatments.
Can CPT 77470 be billed alone?
Yes, CPT code 77470 can be billed at any point during the treatment course, per AMA and CMS guidance.
That said, some payers might bundle it if you bill it on the same day as IMRT (77301) or stereotactic codes—always check their rules.
What is the CPT code 77012?
CPT code 77012 describes computed tomography (CT) guidance for radiation therapy, including planning and on-board imaging, per the AMA.
Use this for initial simulation and daily image-guided radiation therapy, including cone-beam CT.
Can CPT 77295 and 77300 be billed together?
Yes, CPT code 77300 (special teletherapy port plan) isn’t bundled into 77295 (3D radiotherapy plan) or 77301 (IMRT plan), according to CPT coding guidelines.
Just don’t try to bill 77300 separately with 77321 (isodose plan) for the same volume—that’s not allowed.
How often can CPT 77336 be billed?
CPT code 77336 may be billed only once per complete course of therapy with one or two fractions, per AMA CPT instructions.
Don’t use this for single-fraction brachytherapy like prostate seed implants—they’ve got their own codes.
Can CPT 77014 be billed alone?
No, CPT code 77014 can’t stand alone—it needs a radiation treatment delivery code, like 77470 or IMRT codes, per CPT guidelines.
This code covers CT image guidance to direct the beam or track motion during treatment.
What is the difference between 77385 and 77386?
CPT code 77385 handles radiation treatment planning with complex physics calculations, while 77386 adds extra clinical treatment planning physician work for tough cases, like left breast radiation near critical structures.
The split depends on plan complexity and how much physician involvement the case needs.
What is procedure code 77301?
CPT code 77301 describes the preparation of an Intensity-Modulated Radiation Therapy (IMRT) plan, including dose-volume histograms and tolerance specs for target and critical structures, per the AMA.
Bill this once per treatment course—it’s the backbone of IMRT delivery.
Is CPT 55874 covered by Medicare?
Medicare doesn’t have a National Coverage Determination (NCD) for CPT code 55874 (prostate rectal spacer placement), but local Medicare Administrative Contractors (MACs) might cover it.
Always double-check with your MAC before doing the procedure—coverage varies.
What is CPT C1717?
HCPCS Level II code C1717 describes a non-stranded, high-dose-rate brachytherapy source containing iridium-192, billed per source, as defined by CMS.
Use this code for temporary interstitial or intracavitary high-dose-rate brachytherapy procedures.
What is the CPT code for treatment plan?
Clinical treatment planning uses CPT codes 77261 (simple), 77262 (intermediate), and 77263 (complex), per the AMA.
These codes cover the physician’s work to blend patient condition, imaging, and treatment goals into a formal therapy plan.
