HCPCS Code J7999: Compounded Drug, Not Otherwise Classified

Learn about the HCPCS code J7999 for "compounded drug, not otherwise classified" through this short guide.

## **What is the HCPCS code J7999 for?** The HCPCS code J7999 is a J code. J codes designate medication, with a sizable chunk of them being injected. For this code in particular, it is meant to designate "compounded drug, not otherwise classified (NOC)." What this refers to is a custom-prepared medication prepared by a pharmacist to meet the unique and specific needs of an individual patient that can't be met by standard over-the-counter drugs. This custom drug is often made by combining multiple agents, altering concentrations, or modifying dosage forms not otherwise commercially available. Compounding goes beyond the simple reconstitution of a pre-manufactured product per package instructions. Instead, it involves formulation according to the physician's orders under the FDA. Do note that compounded drugs don't have a National Drug Code (NDC), average sales price (ASP), or average wholesale price (AWP). The goal of compounded medicine is to improve patient outcomes by meeting specific health needs that can't be met by standard medication.

## **Documentation requirements for J7999** As with any medication HCPCS code, you'll need to have sufficient documentation to avoid (or at least lower the chances) of your claim being rejected. Here are some of what you need for J7999: - The full name of the patient - The full name and credentials of the healthcare professionals handling the patient, especially the person who created the compounded drug administered - The patient's medical record/history and relevant diagnoses to justify the medical necessity of the compounded drug - Clinical notes that justify why a compounded drug is needed - Clear descriptions of each component drug or biological in the formulation, with the total dosage given in milligrams (mg) or micrograms (mcg) All documentation must be legible, dated, include patient identifiers, and bear the signature of the prescribing physician/healthcare professional.

## **Billing requirements for J7999** Besides the proper documentation requirements above, it's important to take note of or have the following: - The invoice amount supporting pricing, retained and available for contractor review - Specific codes related to the patient's condition (ICD diagnosis codes) and any procedures conducted (CPT codes) - J7999 must be submitted on a single claim line with quantity set to 1. You must also list each drug and the total dosage of each in mg or mcg - Using inappropriate formatting, such as grouping drug and biological names and doses without separation, will result in instant claim rejections - If the compounded drug requires a durable medical equipment (DME) to administer, please append the KD modifier to indicate infusion through DME Please familiarize yourself with CMS/Medicaid services/related proper coding guidelines for J codes, especially concerning units administered, appropriate modifiers, and other such information to avoid claim rejections.
