The first 90 days should move through controlled setup, validated claim flow, backlog stabilization and measured improvement, with clear owners and reports at every stage.
Days 1–30: establish access, ownership and a baseline
The opening month should make the operating model visible. Confirm provider, location and payer records; clearinghouse and remittance access; system roles; bank and posting controls; contact lists; and secure methods for questions. Document who owns eligibility, authorization, coding, charge entry, claim edits, rejections, denials, payments, statements and patient calls. Train both teams on the handoff, not only the software.
Capture a baseline for charge lag, claim volume, rejections, denials, days in A/R, aging distribution, unposted payments and open tasks. Definitions matter. A practice cannot judge improvement if the vendor measures a “clean claim” or “denial” differently. Review the scope agreed during the medical billing price comparison and turn it into a working responsibility matrix.
Days 31–60: validate normal work and exceptions
Once regular claims are moving, examine acknowledgments, front-end rejections, payer denials, corrected claims, appeals, secondary billing and patient balances. Sample records across providers, payers and service types. The goal is not to find a perfect month; it is to prove that incomplete or rejected work enters a visible queue, reaches the right person and returns within a reasonable time.
Review whether the vendor’s reports reconcile to deposits and system totals. Discuss recurring root causes with the practice team. A billing company should not merely correct the same registration or documentation error forever. It should help show where the error begins so managers can improve the front end while keeping medical billing services accountable for the work they accepted.
Days 61–90: stabilize the backlog and improve the process
By the third month, the practice should see a stable cadence for current claims and a separate plan for inherited A/R. Prioritize balances by age, value, payer, filing limits and appeal opportunity. Track whether old work is being resolved, adjusted with support or returned for a practice decision. Avoid using a single recovery percentage that hides what happened to the accounts.
Use denial categories, payer response times, charge lag and staff-question queues to select a few process improvements. Examples may include registration training, authorization checkpoints, documentation prompts or clearer coding escalation. Improvements should be assigned to an owner with a review date rather than left as general recommendations.
Complete a 90-day business review
The formal review should compare the baseline to current results, explain material differences and identify unresolved risks. Review service levels, staff experience, security or access issues, report usefulness, invoice accuracy and upcoming changes such as new providers or locations. Confirm that leadership can retrieve detailed data and that former-vendor access has been removed where appropriate.
Ninety days is a useful checkpoint, not a guarantee that every aging balance has paid. Payer timing, documentation and appeal cycles can extend beyond it. The best outcome is a controlled, measurable workflow with fewer hidden tasks and clearer accountability. Practices preparing to outsource can use the questions to ask a medical billing company before contracting.
Metrics to discuss without oversimplifying performance
Review charge lag, submission lag, front-end rejection rate, payer denial categories, days in A/R, aging distribution, unposted payments and unresolved tasks together. A single percentage can improve while another queue grows. Compare current performance with the agreed baseline and note changes in volume, payer mix or staffing that affect interpretation.
The billing company should explain causes and actions, not merely display a dashboard. The practice should identify decisions it owns, such as registration training or documentation response. A shared review turns the first 90 days into an operating improvement cycle instead of a pass-or-fail sales promise.
Document the next three actions, their owners and review dates. Include one operational issue, one reporting or reconciliation issue and one staff-education need. This keeps the meeting tied to decisions the two teams can actually complete before the next review.
