Boston IVF's Stoneham location at 2 Main St, Stoneham, MA 02180 operates under multiple NPI registrations that reflect the corporate structure of the practice — including a holding entity known as BostonIVF CRMI Holding LLC (CRMI standing for Center for Reproductive Medicine and Infertility). This editorial covers the CRMI holding entity specifically and its role in the Boston IVF Stoneham location. Patients seeking the operating entity profile for the same address should consult the separate Boston IVF – Stoneham editorial. The practice website is at bostonivf.com, and the clinic holds a 4.2-star rating across 31 reviews. Massachusetts has a robust infertility insurance mandate, and the practice is listed among Massachusetts fertility clinics.
Understanding the distinction between the holding company entity and the operating entity at the same address is primarily relevant to patients navigating insurance claims, NPI verification, and prior authorization letters. From a day-to-day clinical perspective, both entities describe the same physicians, nursing staff, laboratory, and physical office at 2 Main St, Stoneham. However, which NPI appears on an insurance claim can affect benefit determination, in-network verification, and the resolution of billing disputes.
Physicians and Clinical Team
Boston IVF is one of the largest and most established fertility practices in New England, with a physician network that includes some of the most published and recognized reproductive endocrinologists in the United States. Physicians at the Stoneham location hold ABOG dual board certification in Obstetrics & Gynecology and in Reproductive Endocrinology & Infertility, and many hold academic appointments at Boston-area medical schools.
Boston IVF's scale — it is among the highest-volume IVF programs in the country — means its physicians and embryology team have substantial procedural experience. The Stoneham location is one of many Boston IVF sites in the Boston metro area; the physician team may rotate across locations, and egg retrievals may be performed at a designated procedure site within the Boston IVF system.

Laboratory and Success Rates
Boston IVF is recognized as a high-volume, high-quality IVF program with one of the largest annual cycle volumes in the country. The practice's laboratory infrastructure supports the full spectrum of embryology services across its network of locations. SART membership subjects annual cycle data to external review and public reporting through the SART Clinic Summary Report and CDC ART Surveillance database.
Patients should review the most current cycle-level data published by the CDC's ART Surveillance program and the SART Clinic Summary Report.
Boston IVF's high volume provides a statistical confidence advantage in published outcomes — large sample sizes produce narrower confidence intervals on published percentages, making the data more reliable as a reference point for individual patients than smaller-volume programs. Patients should confirm which SART registration the CRMI Holding LLC entity reports under versus the operating entity to ensure they are referencing the applicable data.
Patient Experience
Patients at the Stoneham location describe a well-organized clinical environment within Boston IVF's broader system. Stoneham is a Middlesex County community north of Boston, accessible from I-93 and Route 28, serving patients from Woburn, Winchester, Reading, Malden, and Medford who prefer a north-of-Boston location over traveling to Boston IVF's downtown or Waltham sites. As a suburban satellite within a large network, the Stoneham office is designed to provide monitoring and follow-up care locally while egg retrievals and complex procedures may be coordinated at network sites with dedicated procedure rooms.
Boston IVF's brand carries strong name recognition in Massachusetts and New England. Patients beginning a fertility workup often encounter the Boston IVF name early in their research, and the practice's long track record and academic affiliations (including research relationships with Beth Israel Deaconess Medical Center) are frequently cited as reasons for choosing the system.
Considering At-Home Insemination?
Not every fertility journey begins in a clinic. At-home intracervical insemination (ICI) is a lower-cost, private option that suits patients with no known fertility diagnosis — including single parents by choice, same-sex couples, and people who want to try a few cycles before committing to clinical treatment.
At-home insemination kits like those from MakeAMom come with step-by-step instructions designed for donor or partner sperm. Kits are a one-time purchase that can be reused until conception succeeds, require no clinic visit, and arrive in plain, discreet packaging. Many patients use them as a first step while working toward a fertility consultation — or alongside ovulation tracking while they wait for an appointment slot.
If you have a known fertility diagnosis, have been trying for 12 months without success (six months if you're over 35), or your physician has already recommended IUI or IVF, a board-certified reproductive endocrinologist is the right next step.
Insurance and Financing
Massachusetts has a comprehensive infertility insurance mandate. Under M.G.L. c. 175 § 47H and related provisions, fully insured Massachusetts group health plans with six or more employees must cover medically necessary diagnosis and treatment of infertility, including IVF. The Massachusetts mandate requires coverage of up to six oocyte retrievals per insurance contract lifetime. The mandate also covers egg freezing for fertility preservation in patients facing iatrogenic infertility from medical treatment.
Important caveats: self-funded ERISA plans are not bound by state mandates, federal employee health plans differ, and Medicaid does not cover IVF. Patients should confirm whether their plan is a fully insured Massachusetts plan or a self-funded ERISA plan, and which NPI entity — the CRMI Holding LLC or the operating entity — is recognized as in-network by their insurer. Boston IVF's financial and insurance team assists with benefit verification, prior authorization, and the clarification of which entity should appear on claims.
Frequently Asked Questions
What is the CRMI Holding LLC, and why does it have its own NPI? The CRMI Holding LLC is a corporate entity within the Boston IVF system that holds certain contracts, credentialing agreements, or legal relationships associated with the Stoneham location. Healthcare practices commonly create holding structures for operational, liability, or billing reasons. From a patient care standpoint, the holding entity and the operating entity at 2 Main St, Stoneham represent the same clinical location. The NPI distinction matters for insurance billing — claims may be processed differently depending on which entity's NPI appears on the claim.
Do I need to verify in-network status separately for the CRMI Holding LLC versus the operating entity? Yes. If your insurer identifies providers by NPI, you should confirm whether the CRMI Holding LLC NPI and the operating entity NPI are both in-network with your plan. If only one is, claims billed under the other entity's NPI may be processed as out-of-network. Boston IVF's billing team can advise on which NPI will appear on your claims.
Are all Boston IVF services available at the Stoneham location? The Stoneham office at 2 Main St handles consultations, monitoring appointments, and certain clinical procedures. Egg retrievals and embryo transfers may be performed at a Boston IVF site with a dedicated surgical procedure room and full embryology laboratory capacity. Confirm with the scheduling team which procedures are performed locally in Stoneham versus at another network site.
What is the wait time for a new patient consultation at Boston IVF Stoneham? Boston IVF is a high-volume practice, and consultation wait times can vary. Patients can contact Boston IVF through bostonivf.com or by phone and request the Stoneham location. The scheduling team can advise on current availability and whether other locations have earlier openings if time is a factor.
