CMS Issues Additional Guidance on Use of the JW Modifier

Published on 

Tuesday, September 6, 2016

The phrase “waste not, want not” means to use one’s resources wisely in order to always have plenty and avoid poverty. Although Medicare pays for drug wastage in certain circumstances, they also expect healthcare providers and suppliers to “use drugs or biologicals most efficiently, in a clinically appropriate manner.” But when waste cannot be avoided, starting next year, CMS is requiring reporting that will allow them to identify and monitor billing and payment for discarded drugs under Medicare Part B.

As promised, CMS has released a list of frequently asked questions concerning the use of the JW modifier. The JW modifier indicates that a portion of a drug or biological was discarded or wasted. Currently the use of the JW modifier is at the discretion of the jurisdictional Medicare Administrative Contractors (MACs). For example, Cahaba GBA, MAC for Jurisdiction JJ (Alabama, Georgia, and Tennessee) does not require the reporting of the JW modifier for wasted drugs/biological. In order to be more consistent and better able to track drug wastage, CMS is requiring the use of the JW modifier nationally effective January 1, 2017, in order for providers/suppliers to seek payment for drug/biological wastage.

The JW modifier is to be used on Part B drug claims for discarded drugs and biologicals (hereafter referred to as drugs) when they are in single-use vials or packaging. If uncertain, the information as to whether a drug or biological is single use can be found in the manufacturer’s packaging insert. The discarded drug amount is the amount of a single use vial or other single use package that remains after administering a dose/quantity of the drug to a Medicare patient. Multiple use vials/packaging are not eligible for Medicare payment for discarded amounts.

The JW modifier will mainly be used for reporting drug wastage in physician offices and hospital outpatient departments (including Critical Access Hospitals (CAHs)). Some suppliers such as pharmacies may need to report the JW modifier, but it is unlikely they will have much, if any, drug wastage. Hospital Part B inpatient claims on a 12X type of bill would also report the JW modifier for separately payable drugs. Eligible and participating 340B providers are not exempt from use of the JW modifier.

One of the main things to remember about the use of the JW modifier is that it only applies to drugs that are separately payable, for example drugs with an OPPS status indicator of G (pass-through drugs) and K (separately payable non-pass-through drugs). In the outpatient hospital setting, this applies to separately payable drugs billed for surgical patients, patients in the emergency room, patients in outpatient clinics, and other outpatients receiving separately payable drugs.

This means that drugs that are not separately paid by Medicare do not require the use of the JW modifier. For example:

  • Drugs provided in rural health clinics (RHCs) and federally qualified health centers (FQHCs) since these are not separately paid,
  • Drugs provided during hospital inpatient admissions (Part A) that are paid under the Inpatient Prospective Payment System (IPPS),
  • Drugs given to an outpatient but combined to an inpatient Part A claim under the 3 day payment window rule,
  • Packaged drugs, such as drugs with an OPPS status indicator of “N” or an SI of “K” that are bundled with comprehensive APCs (see OPPS Addendum D1 for explanation of services packaged with comprehensive APCs)
  • Overfill wastage (CMS has made it clear in the past that overfill, which is any amount of drug greater than the amount identified on the package, is not billable.)

CMS also exempts drugs paid under the Part B drug Competitive Acquisition Program (CAP) although at this time the CAP remains on hold so there is no current list of CAP medications.)

One of the questions not clearly addressed by the FAQs is whether providers and suppliers are required to report drug wastage or can they elect to absorb the cost of discarded drugs. The guidance states that the JW modifier is used in order to obtain payment for the discarded amount of a drug or biological and is not needed if no discarded drug is being billed to the payer. So IF you are going to bill and expect payment for drug wastage, you must use the JW modifier January 1, 2017 and after.

In using the JW modifier on and after January 2017, providers must report the amount of the discarded drug on a separate claim line with the JW modifier. The unit field should reflect the quantity of drug discarded. If the provider is unable to quantify the amount of drug wasted, the JW modifier is not required. Do not report one claim line with combined units for amount of drug administered and wasted. Also realize if the amount of drug administered or the amount of drug wasted is less than the amount described by one HCPCS billing unit, then it is not necessary to use the JW modifier.

Prior to January 1, 2017, providers must follow the directions of their MACs or they may voluntarily report the JW modifier. Providers should check their MACs websites for any specific direction concerning the reporting of the JW modifier prior to the mandatory January 1, 2017 requirement. For example, here is some guidance from a few MACs and you can see that current instructions differ from MAC to MAC – that is why it is important to determine your MAC’s guidance for use of the JW modifier in 2016.

Cahaba GBA - Cahaba DOES NOT require the use of the JW modifier at this time. If providers wish to designate that a portion of a single dose vial is being discarded, please continue to bill the injection on ONE line and add the JW modifier to the procedure code and document the discarded amount in the patents records. Bill for the complete vial, even though part of the vial is being discarded. DO NOT split the billing to two claim lines: one with the JW and one without.

First Coast - For billing purposes, First Coast does not require the use of modifier JW prior to January 1, 2017. Drug wastage is billed by combining on a single line the wastage and administered dosage amount.

NGS - National Government Services does NOT require the use of the JW modifier at this time but providers may choose to use it. Claims will process appropriately with or without the JW modifier. If the JW modifier is used; it should be appended to a separate line for the HCPCS code (separate from the amount administered) indicating the amount (in units) discarded.

One thing CMS and all the MACs agree on is that wastage of the drug must be documented in the patient’s medical record to support the billing of discarded drugs. Here is CMS’s answer to the FAQ concerning documentation of drug wastage:

“CMS expects that providers and suppliers will maintain accurate (medical and/or dispensing) records for all beneficiaries as well as accurate purchasing and inventory records for all drugs that were purchased and billed to Medicare. General guidance on documentation is available in MLN Matters SE 1316. Providers and suppliers should also check with the MAC that processes their Part B drug claims in case additional information on billing and documentation is available at the local level.”

For complete details concerning the JW modifier, see the following CMS guidance:

Providers should use drugs wisely and efficiently, but if wastage cannot be avoided and the provider wants to be paid for it, then understanding the proper use, reporting and documentation for the JW modifier is critical.
