What to Consider
When Choosing a Medical Billing Partner in California
Choose based on fit, not just the biggest promise. Decide whether you need a billing team to manage the revenue cycle, software to support your staff, or both, and make sure the model works with your EHR, payer mix, and California-specific workflows.
Ask every medical billing company in California to define its performance metrics. Clean claim rate, first-pass acceptance, denial rate, and days in A/R can be calculated differently, so make sure you are comparing the same measurements.
- Ask how each performance metric is defined and calculated.
- Confirm the team works with your existing EHR and California payer workflows.
- Get pricing, included services, and extra charges in writing.
- Before switching vendors, check data ownership, notice periods, and open-claim handling.

Ask Questions
Frequently Asked Questions
Hear from our healthcare clients on how they recovered outstanding workers’ compensation and personal injury debts, optimizing their revenue cycle.
Which medical billing company is best for a California practice?
No single company is best for every practice. Compare specialty experience, payer knowledge, service scope, reporting, security, pricing, and implementation. A surgery center, behavioral health clinic, and primary care group will not need the same billing workflow.
Do medical billing companies need a California office?
How much do medical billing companies charge?
Pricing may be based on a percentage of collections, a per-claim fee, a monthly fee, or a mixed model. Ask for the total cost of coding, credentialing, interfaces, old A/R, patient support, reports, setup, and termination.
What should be included in a medical billing proposal?
The proposal should define each task, staffing, system access, reports, response times, pricing, exclusions, implementation, work on old A/R, security responsibilities, and termination support.
What should I ask about Medi-Cal billing?
Does the practice need a business associate agreement?
A billing vendor that creates, receives, maintains, or transmits PHI for a covered entity is generally a HIPAA business associate. The practice should obtain an appropriate BAA and have qualified counsel or compliance staff review it.
How long does it take to switch billing companies?
The timeline depends on system access, clearinghouse setup, payer enrollment, data transfer, open claims, and old A/R. Ask for a written transition plan with dates and named owners.
What is the difference between medical billing and revenue cycle management?
Medical billing usually covers claims, payments, denials, and A/R. Revenue cycle management may also include eligibility, authorization, coding, credentialing, patient balances, reporting, and other work before and after claim submission.
