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

You passed the exam and earned your IBCLC credential. Then someone asks you to assess a tongue tie, a mother asks whether she should take domperidone, or a pediatrician assumes you can diagnose mastitis.

What can you do, and where is the line?

The scope of practice can become unclear when you are the only lactation professional in the room. Knowing its limits protects your patients, your license, and your practice.

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.

The following activities are within 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

The role includes assessment, planning, education, coordination, and documentation. It does not include diagnosis, prescribing, or procedures.

What's outside IBCLC scope

The IBCLC is a clinical credential, not a medical license. Unless you hold another license that authorizes the activity, the following are outside your scope:

Can an IBCLC diagnose?

You cannot diagnose tongue tie, mastitis, thrush, or another medical condition. You can assess and observe, recognize signs, and document what you see. A physician, dentist, or other provider with diagnostic authority must make the formal diagnosis.

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."

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 first statement records an assessment and makes a referral. The second gives a diagnosis that you are 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 such as LactMed or Hale's Medications & Mothers' Milk. A prescribing provider must recommend starting, stopping, or changing a medication.

This also applies to galactogogues. You can discuss the evidence about domperidone or metoclopramide and note that optimization of non-pharmacological interventions (frequent feeding, effective latch, pumping) should come first. 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 states that 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 license. This distinction often causes confusion in scope-of-practice discussions.

An IBCLC who is also an RN can perform nursing activities. An IBCLC who is also an NP can diagnose and prescribe, and an IBCLC who is also a dentist can evaluate and release a tongue tie. Those activities come from the other credential, not the IBCLC credential.

IBCLCs in hospital settings may therefore perform activities that seem "outside scope." They are practicing under a nursing or medical license while applying their IBCLC-level lactation expertise.

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

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

The table below compares the roles in lactation care:

IBCLCs have the deepest lactation-specific training of any provider (95 hours of lactation-specific education required by IBLCE, plus 300 to 1,000 supervised clinical hours focused on breastfeeding, depending on the pathway). Physicians have far less lactation training, but they can diagnose and prescribe. The roles are complementary.

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

IBCLC state licensure: where it stands

In 45+ US states, IBCLCs have no state licensure. The IBCLC is a voluntary international certification issued by a private board, 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

Some states have a form of state-level IBCLC credentialing. These categories affect 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).

Mandatory license with statutory carveouts:

• Massachusetts - Chapter 186 of the Acts of 2024 (H.4999, signed August 2024); per Ch. 186 §54, all individuals required to be licensed to practice lactation consulting had to be licensed by January 1, 2026. Statutory carveouts preserve other licensed professionals and certain perinatal health workers. Confirm current Board of Allied Health Professionals rulemaking status before counting on a license being issuable.

Enacted but not yet effective:

• 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 lead to direct insurance contracting. Payers decide whether to credential solo IBCLCs. 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 May 2026. USLCA is pursuing licensure advocacy in 36 states.

What this means for your practice

If you are starting a private practice in a state without licensure, you will most likely operate cash-pay with superbills at first. That is usually a result of payer rules, not preference. Many commercial payers either do not recognize stand-alone IBCLCs as a credentialable provider class or limit their panels to providers with state licensure. Third-party billing networks such as The Lactation Network contract with some commercial plans and subcontract with individual IBCLCs. This gives many solo IBCLCs a route to in-network reimbursement. Our billing guide covers the superbill workflow, and Commercial Insurance Paneling for IBCLCs covers the Aetna, UnitedHealthcare, Cigna, Anthem, TLN, CAQH, single-case agreement, and incident-to mechanics.

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. Enforcement has been inconsistent, and many plans require the provider to be in-network. That requirement makes licensure relevant to reimbursement.

Can an IBCLC diagnose tongue tie?

Tongue tie is one of the scope-of-practice questions IBCLCs encounter most often.

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? You can share your clinical assessment of how the frenulum appears to affect feeding and explain what the evidence says. The AAP's 2024 clinical report found limited evidence supporting frenotomy beyond severe anterior tongue tie and recommended nonsurgical management first. The 2023 FROSTTIE randomised controlled trial (Knight et al., NIHR HTA WBBW2302) was stopped early because of COVID-19 disruption and slow recruitment; the authors concluded the trial "does not provide sufficient information" to determine whether frenotomy improves breastfeeding outcomes. The decision to proceed with a frenotomy is between the family and their physician or dentist.

Your role is the assessment before the procedure and lactation support afterward. Both are within your scope.

When to refer

Knowing when to refer is part of your scope. Timely referral is both a clinical and legal obligation.

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 the referral in the chart. Record what you observed, why you are referring, and who you referred to. If the patient declines a referral, document that as well. See our documentation guide for charting best practices.

How scope shapes your practice model

Your scope of practice 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). Most non-hospital IBCLCs operate this way. The scope covers work 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. Each professional works within their scope.

Hospital-based. You are typically employed and work under the hospital's protocols. Your scope may be supplemented by your nursing license (if you are 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. The IBCLC scope is the same, but the format is different. You observe, assess visually, guide positioning, and educate. You cannot perform 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.

Each model requires HIPAA-compliant tools and a charting system that supports documentation within your scope. Generic EHRs do not handle lactation-specific assessments, weighted feeds, or feeding plans. You may need workarounds to use the system. See our software comparison for tools built for lactation, or see NuBloom's features.
