IBCLC Scope of Practice: What You Can and Can't Do

You passed the exam. You have your IBCLC. Now someone asks you to look at a tongue tie, or a mom wants to know if she should take domperidone, or a pediatrician assumes you can diagnose mastitis.

Can you? Where's the line?

The IBCLC scope of practice gets fuzzy fast, especially if you're the only lactation professional in the room. Knowing exactly what you can and can't do protects your patients, your license, and your practice. Here's how it actually works.

What can an IBCLC do?

The IBCLC Scope of Practice is published by IBLCE (now the IBCLC Commission) and covers "activities for which IBCLCs are educated and in which they are authorized to engage." The Clinical Competencies document spells out the specific skills.

Here's what's in scope:

• Comprehensive assessment of maternal, infant, and feeding situations related to lactation
• Individualized feeding plans developed in consultation with the mother
• Hands-on assistance with positioning, latch, and feeding techniques
• Breast assessment to determine if changes are consistent with normal lactation
• Infant oral assessment to recognize normal vs. abnormal anatomy and when function appears impaired
• Weighted feeds and milk transfer measurement
• Education and counseling on breastfeeding, pumping, milk expression, storage, and handling
• Evidence-based information on medications, herbs, supplements, and their effects on lactation
• Supplementation plans when supplementation is clinically warranted, including method selection
• Referrals to physicians, specialists, and community resources
• Care coordination with the broader healthcare team
• Documentation using structured clinical formats
• Policy development to protect, promote, and support breastfeeding in healthcare settings
• Education of other health professionals and the community about breastfeeding

That's a broad clinical role. You're assessing, planning, educating, coordinating, and documenting. What you're not doing is diagnosing, prescribing, or performing procedures.

What's outside IBCLC scope

This is where people get tripped up. The IBCLC is a clinical credential, but it is not a medical license. Unless you hold a separate license that authorizes it, these are outside your scope:

Can an IBCLC diagnose?

You cannot diagnose tongue tie, mastitis, thrush, or any other medical condition. You can assess and observe. You can recognize signs. You can document what you see. But the formal diagnosis belongs to a physician, dentist, or other provider with diagnostic authority.

The IBLCE Advisory Opinion on Assessment, Diagnosis, and Referral puts it plainly: "the IBCLC does not 'practice medicine,' nor offer a 'medical diagnosis' or 'treatment' unless the IBCLC has another license or certification providing scope of practice/authority to do so."

What this looks like in practice:

You can say: "I'm observing restricted lingual frenulum function that appears to be affecting the latch. I'd recommend an evaluation by a pediatric ENT or dentist."

You should not say: "Your baby has a posterior tongue tie."

The difference matters. The first is an assessment with a referral. The second is a diagnosis you're not authorized to make.

Can an IBCLC prescribe medication?

You cannot prescribe or recommend medications. You can share evidence-based information about a medication's compatibility with breastfeeding, using resources like LactMed or Hale's Medications & Mothers' Milk. But the recommendation to start, stop, or change a medication must come from a prescribing provider.

This applies to galactogogues too. You can discuss what the evidence says about domperidone or metoclopramide. You can note that optimization of non-pharmacological interventions (frequent feeding, effective latch, pumping) should come first. But you cannot tell a patient to take a specific drug.

Can an IBCLC perform a frenotomy?

You cannot perform frenotomies (tongue-tie releases). The IBLCE Advisory Opinion on Frenulotomy is clear: frenulotomy "is not expressly covered in the IBLCE SOP" and is not authorized unless you are "separately licensed or authorized to perform frenulotomies" in your jurisdiction.

In the US, frenotomies are performed by physicians (pediatric ENTs, pediatricians) or dentists. Your role is the pre- and post-procedure assessment, not the procedure itself.

The dual-credential exception

If you hold another license in addition to your IBCLC, you can perform activities within the scope of that other license. This is a big deal and it's the reason scope of practice conversations can get confusing.

An IBCLC who is also an RN can perform nursing activities. An IBCLC who is also an NP can diagnose and prescribe. An IBCLC who is also a dentist can evaluate and release a tongue tie. They're not doing those things as an IBCLC. They're doing them under their other credential.

This is why you'll sometimes see IBCLCs in hospital settings doing things that seem "outside scope." They're not. They're practicing under their nursing or medical license, with IBCLC-level lactation expertise on top.

If your only credential is the IBCLC, your scope is the IBCLC scope. Full stop.

IBCLC vs. CLC vs. physician: scope of practice compared

Here's where each provider fits in lactation care:

The gap in the current system: IBCLCs have the deepest lactation-specific training of any provider (90+ hours of lactation education, 300-1,000 clinical hours focused on breastfeeding). But physicians, who have far less lactation training, are the ones who can diagnose and prescribe. The best clinical outcomes happen when both work together.

For a deeper comparison of CLC vs. IBCLC credentials, see our credential comparison guide.

IBCLC state licensure: where it stands

Here's the thing most people outside the field don't realize: in 45+ US states, IBCLCs have no state licensure. The IBCLC is a voluntary international certification issued by a private board. It's not a state-issued license.

Without state licensure, IBCLCs in most states:

• Cannot contract directly with insurance companies as in-network providers
• Cannot bill Medicaid or TRICARE directly
• Lack formal legal recognition as licensed healthcare providers
• Have no state-level regulatory framework protecting or governing their practice

States with IBCLC licensure

A handful of states have some form of state-level IBCLC credentialing, and the distinctions matter for insurance paneling.

Mandatory practice license (practice is legally restricted to licensees):

• Oregon - stand-alone lactation consultant license through the Oregon Health Authority, active since December 2017 (ORS 676.669). The most mature US framework.
• Rhode Island - state license authorizing independent management of lactation care and services (216-RICR-40-05-27).

Enacted but not yet fully operational:

• Massachusetts - Chapter 186 of the Acts of 2024 (H.4999, signed August 2024); statutory transition deadline was January 1, 2026, with implementing rules (259 CMR) finalizing.
• Connecticut - Public Act 25-168 (SB 1373 / HB 7287) creates mandatory IBCLC licensure under the Commissioner of Public Health, effective July 1, 2026.

Voluntary state certification / title protection (the state protects a title or offers a voluntary credential but does not restrict the practice itself):

• New Mexico - Lactation Care Provider Act (NMSA 1978 §§ 61-3B-1 et seq.; 2017 statute, 2018 rules); only licensees may use the "licensed lactation care provider" (LLCP) title. Practice is not restricted.
• New Hampshire - RSA 310-A:222 (signed 2024) directs the Office of Professional Licensure and Certification to establish a voluntary lactation service provider certification; OPLC rules Plc 1900 became effective January 16, 2026. The certification is primarily tied to Medicaid reimbursement; practice itself is not restricted.

Formerly licensed:

• Georgia - in Raffensperger v. Jackson (May 2023), the Georgia Supreme Court unanimously struck down the Lactation Consultant Practice Act as unconstitutional. The board has been disbanded and no license is required to practice.

A note on Washington: secondary summaries sometimes cite SB 5470 (2023) as creating a state-certified lactation consultant credential. The official bill history shows SB 5470 was reintroduced in 2024 and retained in present status rather than enacted, so Washington is not a current licensure or voluntary-certification state.

State licensure does not automatically translate into direct insurance contracting. Payers make their own decisions about whether to credential solo IBCLCs, and voluntary certification may not satisfy a payer's "licensed independent practitioner" test because the practice itself is not restricted to credentialed providers. New York (A3526) and New Jersey (A1643) continue to introduce comprehensive licensure bills each session; neither has passed as of April 2026. USLCA is pursuing licensure advocacy in 36 states.

What this means for your practice

If you're in a state without licensure and you're starting a private practice, you're most likely going to operate cash-pay with superbills - not because you chose to, but because most commercial payers either don't recognize stand-alone IBCLCs as a credentialable provider class or gate their panels on state licensure. Third-party billing networks like The Lactation Network contract with some commercial plans and sub-contract with individual IBCLCs, which is the other practical route to in-network reimbursement in most states. Our billing guide covers the superbill workflow.

The Affordable Care Act requires most commercial plans to cover "comprehensive lactation support and counseling by a trained provider" at no cost to the patient. But enforcement has been inconsistent, and many plans require the provider to be in-network, which circles back to the licensure problem.

Can an IBCLC diagnose tongue tie?

This deserves its own section because it's the scope-of-practice question IBCLCs deal with most.

Can you assess for tongue tie? Yes. Assessing infant oral anatomy and recognizing when function appears impaired is explicitly within IBCLC scope. You can use published assessment tools like the Hazelbaker Assessment Tool for Lingual Frenulum Function (HATLFF).

Can you diagnose tongue tie? No (unless you hold a separate medical or dental license).

Can you release a tongue tie? No (unless you hold a separate license authorizing it).

Can you refer for evaluation? Yes, and you should when your assessment suggests restricted function is affecting feeding.

Should you recommend for or against a frenotomy? This is where it gets nuanced. You can share your clinical assessment of how the frenulum appears to be affecting feeding. You can share what the evidence says. The AAP's 2024 clinical report found limited evidence supporting frenotomy beyond severe anterior tongue tie. A 2023 randomized trial (the FROSTTIE study) found no evidence of a difference between frenotomy and observation at three months, though the trial was underpowered and the authors noted it "does not provide sufficient information" to draw firm conclusions. The decision to proceed with a frenotomy is between the family and their physician or dentist.

Your role is the assessment before and the lactation support after. That's valuable work, and it's fully within your scope.

When to refer

Knowing when to refer is as much a part of scope as knowing what you can do. Timely referral is both a clinical obligation and a legal one.

Refer when you observe:

• Signs of infection requiring medical diagnosis and treatment (mastitis, thrush, breast abscess)
• Suspected tongue tie or other oral structural issues affecting feeding
• Infant weight loss or failure to thrive beyond what feeding interventions can address
• Maternal mental health concerns (postpartum depression, anxiety)
• Conditions requiring medical workup (thyroid dysfunction, PCOS affecting supply)
• Any situation where the patient needs diagnostic testing, medication, or a procedure

Refer to whom:

• Pediatrician or family physician for infant weight, jaundice, or feeding concerns
• Pediatric ENT or dentist for oral structural evaluation
• OB/GYN for maternal breast pathology or hormonal concerns
• Mental health professional for postpartum mood disorders
• Speech-language pathologist for complex oral motor issues

Document your referral in the chart. Note what you observed, why you're referring, and who you referred to. If the patient declines a referral, document that too. This is basic legal protection and it's good clinical practice. See our documentation guide for charting best practices.

How scope shapes your practice model

Your scope of practice directly affects how you structure your business.

Solo private practice. You handle assessment, care plans, education, and referrals. You bill cash-pay with superbills in most states. You need your own liability insurance ($100-400/year). This is how most non-hospital IBCLCs operate, and the scope is plenty broad enough to run a full practice. You're managing everything from first-latch support to complex multi-visit cases with low supply, NICU transitions, and return-to-work pumping plans.

Collaborative practice. You work alongside a pediatrician, OB, or midwifery practice. The physician handles diagnoses and prescriptions. You handle the lactation assessment, care planning, and follow-up. This model gives patients the most comprehensive care because nobody's working outside their scope.

Hospital-based. You're typically employed and operating under the hospital's protocols. Your scope may be supplemented by your nursing license (if you're an RN-IBCLC) or other credentials. The hospital's liability insurance usually covers you on premises, but may not cover home visits or phone consultations.

Telehealth. Same IBCLC scope, different format. You observe, assess visually, guide positioning, and educate. You can't do hands-on assessment or weighted feeds virtually, which limits what you can accomplish in complex cases. Many IBCLCs use a hybrid model with in-person initial visits and virtual follow-ups.

Whichever model you choose, you need HIPAA-compliant tools and a charting system that lets you document within your scope efficiently. Generic EHRs don't handle lactation-specific assessments, weighted feeds, or feeding plans. You end up working around the tool instead of with it. See our software comparison for tools built for lactation, or see NuBloom's features.
