If you're planning a home birth, you'll encounter two credential types: CPM and CNM. The letters matter because they reflect different training paths, practice settings, legal status, and costs. Here's what distinguishes them and how to decide which type of midwife fits your situation.
What training does each credential require?
| CPM (Certified Professional Midwife) | CNM (Certified Nurse-Midwife) |
|---|---|
| Apprenticeship or midwifery school | Nursing degree + graduate midwifery program |
| 1,350+ clinical hours, all out-of-hospital | 1,500–2,000 clinical hours, mostly hospital |
| 75 births required (50 as primary) | Varies by program, mostly hospital births |
| NARM certification exam | AMCB certification exam |
| Cannot prescribe medications in most states | Can prescribe medications |
| Licensed in 37 states | Licensed in all 50 states |
CNMs complete a bachelor's degree in nursing, pass the NCLEX to become a registered nurse, work in clinical nursing, then complete a graduate-level midwifery program (typically 2-3 years). Their training includes roughly 1,500-2,000 clinical hours, mostly in hospital settings. They graduate with a master's or doctoral degree.
CPMs complete midwifery training through apprenticeship, midwifery school, or a combination of both, focusing entirely on out-of-hospital birth. The Midwives Model of Care emphasizes physiologic birth without routine medical intervention. Training requires a minimum of 1,350 hours of clinical experience and attendance at 75 births (50 as primary caregiver), all in home or birth center settings.
Both credentials require passing a national certification exam and maintaining continuing education. CNMs take the AMCB exam; CPMs take the NARM exam. Neither is objectively harder, but they test different bodies of knowledge shaped by different practice environments.
Where does each type of midwife actually work?
About 95% of CNM-attended births happen in hospitals. CNMs can prescribe medications, order labs and ultrasounds, and manage higher-risk situations. Some CNMs attend home births, but they represent a small subset of the profession, and their hospital-based training gives them less experience with out-of-hospital birth during their education.
CPMs work almost exclusively in home and birth center settings. As of 2024, CPMs attend roughly 70% of planned home births in the U.S. They cannot prescribe medications in most states and refer clients to physicians for anything outside the scope of low-risk pregnancy and birth.
If you live in a major metro area, you'll likely find both CPMs and CNMs who attend home births. In rural areas, you may only find one or the other, or neither.
What do CPMs and CNMs charge for home birth?
The midwife's credential doesn't determine the fee as much as geography and practice overhead do. That said, typical patterns exist.
CPM fees for full home birth services (prenatal care, birth attendance, postpartum visits) range from $3,000 to $6,500, with most falling between $4,000 and $5,500. CNM fees for home birth typically run $4,500 to $8,000, with higher averages in areas where CNMs are scarce or maintain hospital privileges alongside their home birth practice.
Both types generally require payment in full by 36 weeks. Some offer payment plans. A few accept insurance directly, but most provide a superbill for you to submit for possible reimbursement.
Does insurance cover one better than the other?
CNMs have significantly better insurance recognition. Most private insurance plans and all state Medicaid programs cover CNM services because CNMs are licensed healthcare providers in all 50 states. You'll still need to verify that your specific CNM is in-network and that your plan covers home birth, but the credential itself is not the barrier.
CPMs face patchwork coverage. As of 2024, 24 states require Medicaid to cover CPM services. Private insurance coverage for CPMs varies wildly by state and carrier. Even where CPMs are licensed, many insurers don't credential them.
If insurance reimbursement matters to your budget, confirm coverage in writing before you hire. Ask your midwife how many of her clients successfully get reimbursement and what that process looks like. The credential is only one variable in a complicated equation.
- Does my insurance plan cover your specific credential type for home birth?
- Can you provide a superbill, and do your clients typically get reimbursed?
Is one credential safer than the other for home birth?
No large-scale study has directly compared outcomes between CPM-attended and CNM-attended home births while controlling for risk factors. Both credentials require competency in neonatal resuscitation, managing hemorrhage, and recognizing when to transfer care.
The 2023 MANA Stats database, which tracks CPM-attended home births, shows outcomes comparable to other studies of planned home birth with trained attendants. Studies of CNM-attended home births show similar safety profiles. What matters more than credential is the individual midwife's experience, judgment, and access to timely transfer if needed.
Your safety depends on accurate risk screening, appropriate transfer decisions, and proximity to hospital backup. Ask any prospective midwife about her transfer rate, transfer process, and consultation relationships with physicians. Those answers tell you more than the letters after her name.
Can both credentials legally attend births in your state?
CNMs hold licenses in all 50 states and can legally attend births anywhere, though scope-of-practice laws vary. Some states restrict CNMs from attending home births, require physician supervision, or limit their prescriptive authority.
CPMs are licensed or regulated in 37 states as of 2024. In states without CPM licensure, some CPMs practice under religious exemptions or operate in legal gray areas. In a handful of states, attending a home birth as a CPM is explicitly illegal.
Check your state's current laws through your state health department or the MANA website. If you're considering a CPM in a state where they're not licensed, understand the legal risks, how that affects your access to emergency care if you transfer, and whether your medical records will transfer smoothly to a hospital.
How do you choose between a CPM and a CNM?
Start with who's available and practicing in your area. If only one type practices within a reasonable distance, your decision is simple. If you have options, consider these factors.
If insurance reimbursement is non-negotiable, a CNM gives you better odds. If you want a midwife whose entire training focused on out-of-hospital physiologic birth, a CPM may align better with that priority. If you have any risk factors that sit on the edge of eligibility (like a previous cesarean or mild hypertension), a CNM's ability to prescribe and order tests may let you stay in midwifery care longer.
Interview individual midwives regardless of credential. Ask about their experience, philosophy, backup arrangements, and what situations would lead them to transfer your care. You're hiring a person with judgment and skills, not just a set of initials.
Both CPMs and CNMs can attend safe home births if they're experienced and practice good judgment. Your choice depends more on who's available in your area, what your insurance covers, and which individual midwife you trust. Interview at least two midwives if you can, ask detailed questions about their training and transfer process, and verify insurance coverage in writing before you commit.
