How to Start a Speech Therapy Private Practice

To start a speech therapy private practice in the United States, you need five things: a state license, a legal business entity with an EIN, a National Provider Identifier, liability insurance, and a decision about whether you’ll bill insurance or run private pay. Almost everything on that list can be finished in days or weeks. The exception is insurance credentialing, which typically runs 90 to 180 days per payer, and that one item sets the real timeline for most new practices.

This is a well-worn path, not a leap into the unknown. According to ASHA’s 2024 member survey, 24.3% of Speech-Language Pathologists already work in private practice full or part time. Here is each step in the order most SLPs tackle them, with a source for every claim.

Your license is the legal requirement. The CCC is optional.

State licensure is what legally allows you to practice. The Bureau of Labor Statistics notes that all states require Speech-Language Pathologists to be licensed. The CCC-SLP is a different thing, and ASHA itself is direct about it: “Holding the CCC is voluntary; it is your decision whether or not to apply.” In practice, most private practitioners keep their certification because many payers expect it and it satisfies licensure requirements in many states. But the license is the non-negotiable piece.

Requirements vary by state, and ASHA’s state-by-state hub is the fastest way to check yours. It covers licensure standards, scope of practice, supervision rules, telepractice policy, and continuing education requirements for every state.

One telepractice rule trips people up: you must be licensed both in the state you provide services from and in the state where your client sits at the time of the session. If you plan to serve families across state lines, look at the Audiology and Speech-Language Pathology Interstate Compact, which is rolling out a compact privilege system so you don’t need a separate full license in every member state.

Set up the business entity

The structure you pick decides who is on the hook if something goes wrong. As a sole proprietor, the Small Business Administration puts it plainly: “You can be held personally liable for the debts and obligations of the business.” An LLC separates your house and savings from the practice’s liabilities. An S corp is not a different entity, just a tax election some owners layer on once revenue justifies it. The SBA guide linked above walks through all of it.

There is a catch for licensed professionals: some states restrict which entity types you can form. California, for example, does not allow SLPs to form an LLC at all and requires a professional corporation instead, while many other states offer a professional LLC (PLLC) for the same purpose. Check your Secretary of State’s rules before you file anything.

Once the entity exists, get your EIN directly from the IRS. It is free and issued immediately online, and the IRS warns about this specifically: “Beware of websites that charge for an EIN. You never have to pay a fee for an EIN.”

Get your NPI

The National Provider Identifier is the 10-digit number that Medicare, Medicaid, and private health plans all require in their administrative and billing transactions. There are two types, and a private practice owner often needs both. Type 1 is for you as an individual clinician, and you only ever get one. Type 2 is for the organization, so if you formed an LLC or corporation, the entity gets its own.

Apply online at NPPES, the federal registry. There is no application fee. One thing the CMS fact sheet is explicit about: an NPI is required for Medicare enrollment, but having one does not enroll you in anything. It is an identifier, not a credential.

Insure the practice

Two policies matter, and ASHA’s business guidance distinguishes them: professional liability covers your clinical services, and general liability covers the physical side of running a business, which starts to matter the day you lease space.

The costs are smaller than most people expect. Insureon reports speech therapists pay a median of $56 per month for professional liability and $29 per month for general liability, based on actual quoted policies. HPSO, one of the largest carriers for speech and hearing professionals, writes policies with limits up to $1 million per claim and $3 million aggregate, plus license defense coverage.

Decide how you’ll get paid

This is the fork in the road, and it is the decision that sets your opening date.

Private pay is the fast lane. ASHA’s own business practices FAQ says a practice without insurance contracts can work: “It is possible to prosper, if you weigh the pros and cons.” You set your rates, you get paid at the time of service, and clients who want to chase out-of-network reimbursement can submit a superbill, for which ASHA provides a template. Note one legal requirement: since January 1, 2022, the No Surprises Act requires you to give self-pay clients a good faith estimate of costs.

Insurance brings referral volume but adds months. Credentialing runs through the CAQH Provider Data Portal, which is free for clinicians: you build one profile, share it with the plans you choose, and re-attest every 120 days. Credentialing firms put typical panel approval at 90 to 120 days per payer, often stretching to 150 or 180, and payers generally will not pay for sessions delivered before your approval date. Once in-network, you’ll bill under CPT codes such as 92507 for individual treatment and 92523 for a combined speech and language evaluation.

And one rule that surprises almost everyone: SLPs cannot opt out of Medicare. Physicians can enter private-pay arrangements with Medicare patients; SLPs cannot. You either enroll (through PECOS) or decline Medicare beneficiaries entirely, and an unenrolled SLP who treats one must refund the patient for covered services. Medicaid is state-administered, so check your state agency about direct billing.

What it actually costs to start

ASHA publishes no startup figures, and its FAQ explains why: publishing typical fees “can be interpreted as ‘price fixing,’ a violation of antitrust laws.” The most useful published estimates come from SpeechPathologyGraduatePrograms.org, which tiers it: roughly $4,300 to $7,200 for a home-based or telepractice setup, $11,200 to $21,500 for a mid-range practice, and $24,000 to $41,500 for a full office. The biggest swing is rent, from zero at home to $2,000 to $4,000 a month for leased space.

Those numbers argue for the pattern most SLPs actually follow: start home-based or via telepractice, keep the day job at first, and let the practice earn its way into an office.

How long before you see your first client?

Add up the components rather than trusting anyone’s round number. The EIN is same-day. The NPI application is measured in days. Entity formation depends on your state’s processing times, usually days to a few weeks. Insurance policies bind quickly once quoted. For a private-pay practice, that is the whole list, which is why the paperwork side can fit inside a few weeks of focused effort.

For an insurance-based practice, credentialing is the clock: three to six months from CAQH profile to seeing in-network clients. The same source above notes most new practices take 6 to 12 months to become profitable, and most owners start part time while keeping traditional employment. Plan for that, and start credentialing the moment your entity and NPI exist, because nothing else on the list needs to wait for it.

Getting the first ten clients

Every new practice fills the same three ways: referrals from professionals who already know you, a Google Business Profile, and a website that shows up when parents in your city search. Google decides local rankings on relevance, distance, and prominence, so a verified profile with the right categories plus a site that names your city and services does most of the early work. We wrote a full breakdown of what that site needs in our speech therapy website design service page, and if you’re weighing the do-it-yourself route first, see our comparison of the best website builders for SLPs.

Before you set session rates, know your baseline. Our SLP salary calculator is built on Bureau of Labor Statistics data and shows what employed SLPs earn in your state at every percentile, which is the floor your private practice needs to beat. And when you’re ready to market beyond Google, the SLP social media marketing guide covers channel strategy for practices.
