A charge labeled “NEJM” or “Mass Med Society” on your bank or credit card statement is a subscription fee from the New England Journal of Medicine, published by the Massachusetts Medical Society. The Massachusetts Medical Society is the legal entity that processes the payment, so the same charge can show up under variations of “NEJM,” “NEJM Group,” or “Mass Med Society.” If you don’t recall signing up, the charge often comes from an auto-renewing subscription, a free trial that converted to paid, or a purchase made by someone else with access to the card.
Matching the Charge to a Subscription
NEJM Group sells several products at different price points, so the dollar amount is usually enough to identify which one you’re paying for. For 2026, individual pricing is:
- New England Journal of Medicine: $199 per year for online access.
- NEJM Clinician: $99 per year or $9.99 per month.
- NEJM AI: $199 per year or $19.97 per month.
NEJM Clinician and NEJM AI bill monthly or annually; the flagship journal is typically billed annually.1NEJM. NEJM Clinician 2026 Subscription Agent Info2NEJM. NEJM AI 2026 Subscription Agent Info Sales tax or VAT can push the final amount slightly above the listed price depending on where you live.
A larger charge may be Massachusetts Medical Society membership dues rather than a journal subscription. Regular physician member dues are $450 per year, plus mandatory district society dues.3Massachusetts Medical Society. Membership Dues MMS members get complimentary access to NEJM and NEJM Clinician and a 50% discount on other NEJM Group journals, so a member normally would not see a separate subscription charge for those two titles.4Massachusetts Medical Society.

How To Cancel and Whether You’ll Get a Refund
You can cancel by calling NEJM Customer Service at 1-800-843-6356, Monday through Friday, 8 a.m. to 4 p.m. ET, or by signing in at myaccount.nejm.org and using the online contact form.5NEJM. Frequently Asked Questions If the subscription was placed through a third-party subscription agency, you’ll need to contact that agency instead.
Whether you get money back depends on when the subscription started. Under NEJM Group’s terms of use, subscriptions purchased on or after March 15, 2025, are generally non-refundable: canceling stops the next renewal but doesn’t refund the current term. Subscribers in the United Kingdom or European Union keep a statutory 14-day right of withdrawal for a full refund. Subscriptions that started before March 15, 2025, can be canceled at any time, and the subscriber can choose either to keep access through the paid term or to receive a prorated reimbursement for unused time.6NEJM Group. Terms of Use
NEJM AI has its own rule: cancellations take effect at the end of the current billing term, and refunds for the remaining portion are not available.2NEJM. NEJM AI 2026 Subscription Agent Info
The store page for the flagship journal advertises a “Satisfaction Guaranteed” policy with “no questions asked” cancellation.7NEJM. Subscribe to NEJM NEJM Clinician’s FAQ says the customer care team will “assist you with cancellation and assess refund eligibility based on your subscription.”8NEJM. NEJM Clinician FAQs If the charge is a renewal you had forgotten about, calling and asking directly is usually the fastest way to see what the representative can do.
If You Don’t Recognize the Charge at All
Before disputing, search the email inboxes tied to the payment method for a confirmation from NEJM. Free trials and promotional sign-ups sometimes convert to paid subscriptions quietly, and a household member or colleague with access to the card may have signed up. Members of the Massachusetts Medical Society who see a dues charge should check the MMS billing cycle rather than assume it’s a journal fee.
If none of that explains it, you can dispute the charge with your bank or card issuer. Contacting NEJM customer service in parallel is worthwhile: they can locate the account the charge came from, confirm whether it’s active, and stop future renewals while the dispute is being sorted out.
