Outsourcing billing is a major step for any healthcare practice. Whether you’re a solo practitioner, clinic, or multi-specialty group, the first 90 days with a medical billing company set the foundation for long-term financial health, smoother operations, and improved cash flow.
Many providers feel uncertain during this transition. What happens first? How long before results appear? What changes should you expect?
This guide explains everything clearly—step by step—so you know exactly what to expect, how to prepare, and how to measure success during the first three months.
Why the First 90 Days Matter So Much
The first 90 days with a medical billing company focus on onboarding, system setup, claim cleanup, workflow optimization, and establishing performance benchmarks.
The first three months are not just about submitting claims. They are about fixing past issues, building accurate processes, and aligning billing with payer rules.
During this phase, the billing company learns:
- Your specialty workflows
- Your payer mix
- Common denial reasons
- Coding patterns
- Revenue bottlenecks
At the same time, your practice begins to experience structured billing operations.
Phase 1: Days 1–30 – Onboarding & Data Transition
The first month of the first 90 days with a medical billing company is all about setup and understanding.
Key Activities in Days 1–30
- Secure transfer of patient and billing data
- Access to EHR, PM software, and clearinghouses
- Signing Business Associate Agreements (BAA)
- Review of payer contracts and fee schedules
- Credential verification (if required)
What You May Notice
- Slower billing at first (this is normal)
- Many questions from the billing team
- Deep review of your previous claims
This phase ensures accuracy before volume.

Claim Audit & Revenue Assessment
Most medical billing companies start the first 90 days with a medical billing company by auditing your past claims.
They Evaluate
- Denied and unpaid claims
- Coding accuracy
- Missing modifiers
- Eligibility errors
- Underpayments
This process often reveals hidden revenue leaks that were previously unnoticed.
“Many practices recover lost revenue in the first 90 days simply by correcting old errors.”
Phase 2: Days 31–60 – Process Optimization & Clean Claim Focus
This stage is where improvements become visible.
What Happens During Days 31–60
- Standardized billing workflows are applied
- Coding guidelines are enforced
- Eligibility checks become routine
- Claims are scrubbed before submission
- Denial prevention strategies begin
During this part of the first 90 days with a medical billing company, the goal is to submit clean claims consistently.
Early Signs of Progress
- Reduced claim rejections
- Faster payer responses
- Fewer billing errors
- Improved documentation feedback

Improved Communication & Reporting
By the second month, communication becomes structured.
You Can Expect
- Weekly or bi-weekly status updates
- AR (Accounts Receivable) reports
- Denial analysis summaries
- Payment posting transparency
Clear reporting is a major benefit during the first 90 days with a medical billing company, helping providers track progress with confidence.
Phase 3: Days 61–90 – Stabilization & Performance Growth
The final phase focuses on consistency and measurable outcomes.
What Changes in Days 61–90
- Faster reimbursement cycles
- Stable cash flow patterns
- Improved net collection rates
- Lower AR days
- Better payer compliance
By now, your billing process is no longer reactive—it’s strategic.
This phase completes the first 90 days with a medical billing company by setting long-term benchmarks.
