HOW IT WORKS
Simple steps, handled by me
Billing
1. Reach out. Send me a note through the contact form, and I’ll reply by email to learn about your practice and payers.
2. Easy setup. I connect to your TherapyNotes, SimplePractice, Sessions Health or Tebra account. No EHR? Send your sessions in an Excel sheet or document instead.
3. Clean claims. I submit your claims from your EHR, or enter your sheet into my billing system, Tebra, and submit them for you.
4. You get paid. I follow every claim, work any denials and post your payments, so you never sit on hold.
Credentialing
1. Reach out. Tell me through the contact form which insurance companies you’d like to join.
2. Gather your details. I collect what each insurer needs, such as your license, NPI and CAQH profile.
3. Apply and follow up. I submit the applications and follow up with each insurer, so you don’t spend hours waiting on them.
4. You’re in-network. I let you know by email once you’re approved, so you can start seeing clients with that insurance.
SIMPLE, FAIR PRICING
You only pay for billing when you get paid
Billing
A percentage of what I collect for you, so you only pay when you get paid. A small monthly minimum applies.
Credentialing
A flat fee per insurance company, with a discounted rate when you also use my billing services.
MEET LESLY GUERIN
The details, handled with care.
I started Ellbee part-time to help pay my mother’s medical bills. My first client was a local psychiatrist, and the practice grew through referrals from providers who wanted a biller they could trust and who actually responds.
After she passed, I made Ellbee my full-time work in her honor. The name is a play on her initials: LiliBeth, L.B., Ellbee.
Today LB Services LLC, doing business as Ellbee Services, is a local, woman-owned business in Springfield, MA. Every practice I work with gets my personal attention, quick email replies and honest communication.
