Reducing the Expenditures and Workload Associated With VA Partial-Fill Prescription Processing
Implementing the VA partial-fill guidance and refill education within a pharmacy operation may reduce prescription processing costs.
Discussion
The utility of CMOP among the responding IHS sites varies quite significantly. Some sites appreciate the convenience of CMOP while acknowledging its limitations, such as the possible decrease in insurance collections, lengthy prescription processing time, or medication backorders. However, some sites have reserved CMOP for special circumstances (eg, mailing refrigerated items to the patient’s street address) due to various complexities that may come with CMOP. One site reported that it compares IHS contract drug prices with VA contract drug prices quarterly to determine which prescriptions should be sent through CMOP.
Most of the IHS pharmacists (89%) are trained in CMOP prescription processing. If an IHS site wants to increase its volume of CMOP prescriptions, it is sensible to train as many pharmacists as possible so that the responsibility does not fall on a few pharmacists. Newly hired pharmacists can receive guidance from trained pharmacists. Designation methods for CMOP patients can be beneficial for these pharmacists to identify CMOP-enrolled patients, especially if the site does not require patients to ask for prescriptions to be mailed at the time of refill request. Only 3 sites (7%) use multiple designation methods in addition to relying on patients to ask for prescriptions to be mailed. Proper implementation of designation methods can remove this extra burden on patients. Conversely, requiring patients to ask for prescriptions to be sent through CMOP can prevent spontaneous mail-outs if a CMOP-designated patient wants to pick up prescriptions locally. Overall, 16 sites (36%) rely on patients asking for prescriptions to be mailed.
One of the main benefits of CMOP is the ability to mail refrigerated items. Local pharmacy mail-out programs may not have this ability. Patients at rural locations often use post office (PO) boxes because they are unable to receive postal services at their physical addresses; however, they may receive packages through United Parcel Service (UPS) at their physical addresses. CMOP uses UPS to send refrigerated items, but UPS does not deliver to PO boxes. Therefore, remotely located sites like CHCF have difficulty in fully optimizing this benefit. One solution is documenting both the physical and mailing addresses on the patient’s EHR, which enables CMOP to send refrigerated items to the patient’s home address via UPS and mail the rest of the prescriptions to the patient’s PO box address with the US Postal Service. The physical address must be listed above the PO box address to ensure that refrigerated items are not rejected by CMOP. Furthermore, both the physical address and the PO box address must be in the same city for this method to work. Two sites noted mailing refrigerated items as one of the major challenges in CMOP prescription processing.
CMOP-enrolled patients must be educated about requesting medications 7 to 10 days before they run out. There is no standard time line for prescriptions filled by CMOP. However, 1 site reported that it may take up to “10 days from time requested to mailbox.” This delay leads to pharmacies facing a dilemma as processing prescriptions too early can lead to insurance rejections, but processing them too late can lead to the patient not receiving the medication by the time they run out of their current supply. However, CMOP provides the ability to track prescriptions sent through CMOP. Pharmacists and technicians need to have access to BestWay Parcel Services Client Portal (genco-mms.bestwayparcel.com) to track CMOP packages. Tracking CMOP prescriptions is a way pharmacy technicians can be involved in CMOP prescription processing. Technicians seem to be underutilized, as only 27% of the responding sites utilize them to some degree in the CMOP process. One site delegated the responsibility of checking CMOP rejection messages to pharmacy technicians. Since 2 of the responding sites do not check CMOP rejection messages at all, this is an excellent opportunity to get pharmacy technicians involved.
A CMOP auto-refill program can potentially be utilized to avoid missed or late medications. In an auto-refill program, a pharmacist can refill prescriptions through CMOP on the due date without a patient request. They may get rejected by insurance the first time they are processed through CMOP for refilling too early if the processing time is taken into account. However, the subsequent refills do not have to consider the CMOP processing time as they would already be synchronized based on the last refill date. Though, if CMOP is out of stock on a medication and it is expected to be available soon, CMOP may take a few extra days to either fill the prescription or reject it if the drug stays unavailable. One of the sites reported “the amount of time [CMOP] holds medications if they are out of stock” as “the hardest thing to work around.” A couple of sites also mentioned the longer than usual delay in processing prescriptions by CMOP during the holidays as one of the major challenges.
CMOP use of repackaged products also may lead insurance companies to deny reimbursement. Repackaged products are usually cheaper to buy.14 However, most insurances do not reimburse for prescriptions filled with these products.15 The local drug file on RPMS may have a national drug code (NDC) that is reimbursable by insurance, but CMOP will change it to the repackaged NDC if they are filling the prescription with a repackaged product. One potential solution to this problem would be filling these prescriptions locally. Furthermore, insurance claims are processed when the prescriptions are filled by CMOP. Sites cannot return/cancel the prescription anymore at that point. Therefore, the inability to see real-time rejections as the medication orders are processed on-site makes it challenging to prevent avoidable insurance rejections, such as a refill too soon. One site calculated that it lost $26,386.45 by utilizing CMOP from January 9, 2018 to December 12, 2018. However, it is unclear whether this loss was representative of other sites. It is also worth noting that IHS sites can save a substantial amount of money on certain products by utilizing CMOP because VA buys these products at a reduced price.16
CMOP-transmitted prescriptions can be rejected for various reasons, such as CMOP manufacturer’s backorder, a different quantity from CMOP stock size, etc. Information about these rejected prescriptions is accessed through electronic messages on RPMS. CMOP does not dispense less than a full, unopened package for most over-the-counter (OTC) medications. The quantity on these prescriptions must be equal to or multiples of the package size for them to be filled by CMOP. This can lead to a patient having prescriptions with different days’ supplies, which results in various refill due dates. If a site has a local mail-out program available, it can potentially keep the same days’ supply for all prescriptions by mailing these OTC medications locally rather than utilizing CMOP. However, this can partially negate CMOP’s benefit of reduced workload.
CMOP also has specified quantities on some prescription medications. One survey respondent viewed “the quantity and day supply required by CMOP” as a negative influence on the site’s insurance collection. It is possible that CMOP does not carry all the medications that a CMOP-enrolled patient is prescribed. Most sites (77%) still send eligible prescriptions through CMOP for the patients who also have CMOP-ineligible prescriptions. There are a small number of sites (14%) that utilize local mail-out program for the patients with any CMOP-ineligible prescriptions, possibly to simplify the process. Schedule II controlled substances cannot be processed through CMOP either; however, facilities may have local policies that prohibit mailing any controlled substances.
Prescriptions can be manually transmitted to CMOP, or they can be automatically transmitted based on the run time and frequency of the auto-transmission setup. The prescriptions that are waiting to be transmitted to CMOP must be in the “suspended” status. The apparent advantage of relying on auto-transmission is that you do not have to complete the steps manually to transmit suspended CMOP prescriptions, thereby making the process more convenient. However, the manual transmission can be utilized as a checkpoint to verify that prescriptions were properly suspended for CMOP, as the prescription status changes from “S” (suspended) to “AT” once the transmission is completed. If a prescription is not properly suspended for CMOP, the status will remain as S even after manual transmission. More than half (59%) of the responding sites must find the manual transmission feature useful as they use it either over or in addition to the auto-transmission setup.
Despite the challenges, many IHS sites process thousands of monthly prescriptions through CMOP. Of the 94 CMOP-enrolled IHS sites, 17 processed > 1,000 prescriptions from March 27, 2019 to April 25, 2019.17 Five sites processed > 5,000 prescriptions.17 At the rate of > 5,000 prescriptions per month, the yearly CMOP prescription count will be > 60,000. That is more than one-third of the prescriptions processed by CHCF in 2018. By handling these prescriptions through CMOP, it can decrease pharmacy filling and dispensing workload, thereby freeing pharmacists to participate in other services.18 Furthermore, implementing CMOP does not incur any cost for the IHS site. There is a nondrug cost for each prescription that is filled through CMOP. This cost was $2.67 during FY 2016.19 The fee covers prescription vial, label, packaging for mail, postage, personnel, building overhead, and equipment capitalization.19 The nondrug cost of filling a prescription locally at the site can potentially exceed the cost charged by CMOP.19
A lack of objective data exists to assess the net impact of CMOP on patients. Different theoretical assumptions can be made, such as CMOP resulting in better patient adherence. However, there is no objective information about how much CMOP improves patient adherence if it does at all. Though J.D. Power US Pharmacy Study ranks CMOP as “among the best” mail-order pharmacies in customer satisfaction, only 3 of the 44 responding sites have measured patient satisfaction locally.20 Only 1 site had objective data about CMOP’s impact on the point of sale. Therefore, it is currently difficult to perform a cost-benefit analysis of the CMOP program. There are opportunities for further studies on these topics.
