We offer complete


Our highly qualified billing team works your claims directly.  Your work doesn’t just fall into a general queue. 

You will know who your main contact is and will communicate with them directly; our team will become an extension of your office staff.  We whole-heartedly believe in the power of real people.  While you need good software to get billing done, you need real people behind the software to watch everything on your account and to be invested in your success. We work hard to build relationships of trust with all of our clients. 



Billing & Claims Submission

We handle the billing of all of your claims, making sure they are being accepted electronically.  We let you know if we see any issues with your coding or charting and we ask you for clarification. 

Our goal is to ensure you bill everything possible and maximize your reimbursement, while ensuring the billing is correct.

Payment Posting

We set you up for Electronic Remittance Advice (ERA).  We look over the ERAs to make sure you are being paid correctly, and we post the occasional paper EOB. 

If a claim didn’t process correctly, we leave it on your Accounts Receivables so we can fight for proper processing.

Claims Follow Up & AR Clean Up

Our aging team works every outstanding claim every month until it is processed correctly.  No exceptions. We believe this is our secret sauce, because we truly think that most billing companies drop the ball when it comes to careful and persistent follow-up. 

If your Accounts Receivable is a mess, we are very good at cleaned it up and keeping it clean.  We note all of our efforts in the software so that you can see everything that we are doing.  We use online portals, call insurance companies, ask for supervisors to expedite claims as needed, and automatically and aggressively appeal denials.  Our appeals are extremely effective. 

Patient Collections

Our specialized team sends out the monthly statements, makes friendly follow-up calls to your patients, arranges for payment plans as needed, answers patient questions about their bill, and even takes payments over the phone.

We work the accounts for 90 or 120 days (your preference) and then we refer them to outside collections with your approval.  We often get positive comments from patients about how much they enjoy working with our team.

Patients want a clear understanding of their insurance claims and the portion they’re responsible to pay and our expert service team can take the time to provide this clarity.  


Eligibility & Authorizations

We can check eligibility and benefits using online portals and software tools, or we can teach your front office staff how to do this.

We offer full verification of benefits for midwifery and birth center accounts, and we can customize solutions as needed for other specialties. 

We can obtain prior authorizations as needed or help your front office staff to implement good protocols to ensure authorizations are in place prior to the time of service. 


Every account needs good billing software, but you also need real people managing that software. We can work in any software system, but we do recommend an excellent billing software.  

CollaborateMD (CMD) is our billing software of choice. CMD has great features including reports, scheduling and many other functions. Of the dozens of platforms we have used over the years, we find CMD to be the most user-friendly and efficient system. We have enjoyed their platform for more than 11 years an we can provide a demo of the software if your practice is interested.

A few things to note:

  • We provide training and the tools to help your staff learn CMD.
  • Includes a great scheduler. Appointment reminders via text messages or phone calls are also an option.
  • Your front office staff can enter all patient demographics and payments into CMD.
  • CMD interfaces with several EMRs, and some of the interfaces are free. Their list of EMR partners is here.

Easy File Sharing

All of our clients are provided with a SharePoint account for document sharing and storage. You can easily upload any documents to us without worrying about HIPAA, and you can see all documents that you have ever uploaded.

Combined Years of Experience

“We have been with Larsen Billing Service since Nov. 2018 and have been absolutely impressed throughout our relationship! They have a very efficient Credentialing Department that completes all credentialing matters in short order.  Since we have been with Larsen Billing Service, our AR has decreased by >40%! Aside from the increase in revenue, as well as collections from past due accounts, the most beneficial aspect of our relationship with Larsen Billing Service is the comfort of knowing beyond a doubt that our billing and credentialing is correct and professionally managed. I know that we at the Armadillo wholeheartedly recommend Larsen Billing Service and that you will be as pleased as we have been!”
