## **What is the HCPCS code J3241 for?**
The HCPCS code J3241 is for an injection of teprotumumab-trbw, specifically a dosage of 10 mg. The purpose of this injected medicine is to treat active thyroid eye disease (thyroid-associated ophthalmopathy) that emerges as a result of problems like Graves' disease.
What this intravenous medication does is reduce the effects of inflammation and the size of swelling. It reduces proptosis and double vision as well.
Whether you're about to inject an initial dose or your patient is back for subsequent infusions, don't forget standard clinical practice guidelines and prepare the IV drip setup, teprotumumab, and vital signs monitoring equipment so you can properly administer the medicine and observe the patient for any adverse reactions. Make sure you apply proper medical management for allergic reactions (if any) and blood sugar levels.
## **Documentation requirements for J3241**
As with any procedure, especially involving injecting drugs into patients, it's important to document the following before you file for a claim that includes this code:
- The full name of the personnel who administered the injection + their credentials
- The name and address of the facility where the injection was administered
- The full name of the patient
- The date and time of the drug administration by injection
- Patient records showing they have been diagnosed with thyroid eye disease
- Blood test results that show thyroid function-related information
- Any CT or MRI scans of their eye anatomy, especially if there's eye bulging
- The exact dosage
## **Billing requirements for J3241**
Besides the documentation requirements above, please note the following billing guidelines for this HCPCS code:
- They must reflect the dosage given throughout the treatment.
- Use either of two modifiers: JW if there's unused medication in a vial (wastage), or JZ if there's no unused medication.
Since this is a type of medicine administered via intravenous infusion, please make sure that the CPT code 96365 accompanies all the other codes you're using.
Make sure to always follow medical policies related to all these codes as mandated by the CMS.
