Many pharmacies struggle with identifying which metformin ER product they can dispense or substitute. There are three different strengths and three different extended-release mechanisms. The FDA uses Therapeutic Equivalency (TE) codes to show which generic products can be substituted for a specific brand name. When there are multiple branded versions of an identical active drug ingredient, form, and route of administration, then the FDA must assign each brand an additional identifier such as AB, AB1, AB2 and AB3. The brand names below are different due to their extended-release mechanisms. Generic versions may only be substituted for the brand with the same TE code.
| Brand Name |
Strengths (mg) |
FDA Orange Book
TE Codes |
Extended-Release Format |
| Glucophage XR® |
500, 750 |
AB, AB1 |
Dual hydrophilic polymer system |
| Fortamet® |
500, 1000 |
AB2 |
Single-Composition Osmotic Technology (SCOT) |
| Glumetza® |
500, 1000 |
AB3 |
Gastric Retention Technology |
For example, if you receive a prescription for Fortamet® 1000 mg, you may dispense with the brand name product or a generic formulation with a TE code of AB2

DMEPOS Targeted Probe and Educate Program – Process Improvement Plan
In the October 2021 Newsline article CMS Resumes Targeted Probe and Educate Program to Improve Billing Accuracy and Reduce Claim Denials and Appeals available to PAAS Audit Assistance members on the Member Portal, PAAS National® analysts provided details about Medicare’s Targeted Probe and Educate Program (TPE). Since then, there has been a sharp increase in the number of TPE audits on diabetic testing supplies. Many pharmacies have already received an initial 10-claim “probe”, and some have moved on to round one, an evaluation of an additional 20 to 40 claims.

New Tools Available! Biologic and Non-Biologic Injectable Medication Reference Charts
Ever wonder if you were billing the correct NDC for a Humira® prescription and had to spend precious time investigating? Or how about questioning if you were billing the correct package size for Gvoke® and had to consult multiple references just to try and figure out the answer?

A Need for a Compliance Program – Attest with Confidence
Since 2009, PAAS National® Fraud, Waste & Abuse and HIPAA Compliance program was designed to meet the CMS requirements, with the full support of our expert staff – pharmacists and technicians just like you, with years of experience helping community pharmacies with FWA and HIPAA compliance. Don’t be fooled by offers for training and exclusion checks – work with the best compliance program available to community pharmacies!
Consider the following:
Humana’s 2022 Notice of Program Requirements
Humana’s Compliance Policy for Contracted Healthcare Providers explicitly states pharmacies must have a compliance program that meets the seven elements outlined by CMS, including written policies, procedures and standards of conduct. Per the 2022 Pharmacy Compliance Education and Training Requirements FAQs: “Humana reserves the right to request documentation (e.g., policies and tracking records) confirming that your organization has an effective compliance program that meets the requirements outlined in the Compliance Policy and Standards of Conduct.”
PerformRx Pharmacy Compliance Attestation 2022/2023
PerformRx requires attestations to the following:
The pharmacy has implemented and maintains a compliance program that is consistent, at minimum, with applicable federal and state requirements, including, but not limited to the standards set forth in 42 CFR §423.504(b)(4)(vi) and other Centers for Medicare & Medicaid Services (CMS) guidance set forth in the Medicare Part D Prescription Drug Benefit Manual.
Be proactive. Be prepared. Be protected. Ensure you have all your compliance bases met so that when you attest to having one, you can provide proof if requested for credentialing or audit.

Is Your Pharmacy Ready for an Unannounced Audit?
Pharmacies are often startled with the limited amount of time a PBM offers prior to an onsite audit. However, PBM auditors, DEA agents, FDA inspectors and state Board of Pharmacy inspectors can also make unannounced visits.
Ensuring your staff members are prepared in case of an unannounced visit is essential. Since these visits occur without warning, the Pharmacist-in-Charge (PIC) and/or owner may not be working or available to assist. Keeping information in a central location and advising staff on how to handle these intimidating visits will make the process go much smoother.
PAAS National® has created a document to help pharmacies prepare for PBM visits. Located on our website, under the Tools & Aids Section, you can find our Onsite Credentialing Guidelines. This tool provides a list of frequently asked questions from auditors. The guide also includes references to the Policy and Procedure Manual for PAAS National® Fraud, Waste & Abuse and HIPAA Compliance members.

Beware: DEA and Wholesalers are Cracking Down on Controlled Substance Dispensing
Take note – the DEA is coming after pharmacies dispensing illegitimate controlled substance prescriptions. Pharmacists should all be aware of their corresponding responsibility and the need for a legitimate medical purpose when dispensing controlled substance prescriptions. A review of recent Department of Justice settlements provides guidance on some prescriptions that require additional scrutiny.
Consider the following dispensing activities to be of high risk:
