Prostate Brachytherapy From Pre- to Post-Implant Sim

Don't report a liquid radioactive source code for seeds

In addition to the initial visit and treatment planning for prostate brachytherapy, you should know how to report the pre-implant simulation, the isodose plan, the brachytherapy procedure, and post-treatment planning.

If you do not know how to code for each of these encounters, your oncology office risks misreporting, which could lead to lost reimbursement or worse - an audit.

Last month, we looked at the first two stages of brachytherapy coding: the patient's initial encounter with the oncologist and treatment planning. Read on for the second half of our prostate brachytherapy coding clinic.

Pre-Implant Sim Is Complex

When the oncologist performs volume and mapping services before inserting the catheters for prostate seeds, you should report 76873 (Ultrasound, transrectal; prostate volume study for brachytherapy treatment planning [separate procedure]). After the volume and mapping services are complete, the oncologist is ready to perform the next two steps in brachytherapy treatment: brachytherapy source verification and isodose calculations.

The physician achieves the source verification with a simulation, says Sandy McMaster, outpatient oncology financial specialist at Edward Cancer & Radiation Centers in Lisle, Ill.

There are four simulation codes to choose from; however, you'll report prostate brachytherapy source verification with 77290 (Therapeutic radiology simulation-aided field setting; complex), says Cindy Parman, CPC, CPC-H, RCC, president elect of the AAPC National Advisory Board and co-founder of Coding Strategies Inc., in Dallas, Ga.

Other Sim Levels Have Codes, Too

There are codes for the other levels of simulations, but you likely won't use them in prostate brachytherapy, Parman says. For example, let's say your oncologist conducts a simulation on one treatment area using a single port or parallel-opposed ports. This is a simple sim, which you would report with 77280 (...simple).
For two separate treatment areas with three or more converging ports, report 77285 (...intermediate).
 
Note: You do not use 77280 or 77285 in prostate brachytherapy scenarios, Parman says. "While 77280, in the form of a verification simulation, is used for other types of brachytherapy, neither of these simulation codes are used for prostate seeds," she says

3-D Sim Rare But Possible: You may be able to report a three-dimensional simulation in certain instances with CPT code 77295 (... three-dimensional), according to CPT.
 
"The reporting of a 3-D simulation/plan with prostate seed brachytherapy varies based on individual payer guidelines," Parman says. "For example, Wisconsin Physician Services (WPS) Medicare states: '3-D reconstruction of tumor volume and critical structure volume in brachytherapy cases to develop a DVH.' "

When coding for a 3-D sim, you should report 77295.

You may need modifier -26: If your oncologist performs any type of simulation in a hospital setting, you must append modifier -26 (Professional component) to the simulation code. The hospital will also report the procedure with the appropriate code (no modifier is required for the hospital).

Isodose Plans Often Complex ... But Not Always

After the pre-implant sim, the physician will order an isodose plan, the final step in the treatment before the actual brachytherapy begins. The oncologist orders an isodose plan to "determine the exact delivery of radiation around the brachytherapy radiation sources and the radiation dose that will be given to adjacent normal structures," McMaster says.

There are three levels of brachytherapy isodose service; the more sources the oncologist uses, the higher the level of service. When your oncologist gives a patient a brachytherapy treatment, you should:
 

  •  report 77326 (Brachytherapy isodose plan; simple [calculation made from single plane, one to four sources/ribbon application, remote afterloading brachytherapy, 1 to 8 sources]) for eight sources or fewer
     
  • report 77327 (... intermediate [multiplane dosage calculations, application involving 5 to 10 sources/ribbons, remote afterloading brachytherapy, 9 to 12 sources) for 9-12 sources.
     
  •  report 77328 (...complex [multiplane isodose plan, volume implant calculations, over 10 sources/ribbons used, special spatial reconstruction, remote afterloading brachytherapy, over 12 sources]) for more than 12 sources.

    Brachytherapy Delivery Method Vital to Coding

    The physician will deliver the actual brachytherapy treatment next. Choose your brachytherapy code based on the type of radioactive source and the delivery method.   (Want a quick reference that breaks down all the brachytherapy codes? See "Clip and Save: Code Correctly With Brachytherapy Checklist" later in this issue.)

    When your physician uses liquid radioactive sources, report 77750 (Infusion or instillation of radioelement solution [includes three months follow-up care]). Oncologists most often use this technique to treat malignant effusions in the pleural or peritoneal cavities,  Parman says.

    Radioactive ribbons are interstitial: When the oncologist inserts seeds, needles, ribbons or wires containing radioactive materials into body tissues, you should report 77776-77778 (Interstitial radiation source application ...). When the oncologist performs this procedure in a hospital, don't forget to append modifier -26 to the proper application code to show that you are only reporting the professional component of the service.

    For example: Your physician performs complex interstitial radiation source application on a patient in a hospital setting. On your claim, you should:
     

  •  report 77778 (... complex) for the source application
     
  •  attach modifier -26 to 77778 to show that you are only coding for the professional component of the procedure.

    Caveat: CPT considers many hospital services (admit, visits, discharge, etc.) bundled into the brachytherapy codes. If you're reporting a separate service in addition to a brachytherapy source application code, be sure to make sure the service isn't bundled.

    Post-Treatment Sims Are Usually Complex

    After the initial brachytherapy treatment, you might be able to report several post-treatment services, McMaster says. For example, the oncologist may want to verify the source of radiation by repeating isodose planning or performing another complex simulation.

    When your oncologist performs sims and reviews isodose plans post-brachytherapy, you should report them the same way you would have pre-brachytherapy, McMaster says.

    For instance, a patient reports for a complex, post-brachytherapy isodose plan in an office setting. On the claim, you should report 77328 for the encounter, just as you would have for a pre-brachytherapy isodose plan.

    Most post-treatment simulations and isodose plans are complex, McMaster says. Sometimes, a three-dimensional simulation is even necessary after the brachytherapy, she says.
