Switching medical billing companies: a handoff checklist for independent practices

By Vyro Medical Billing · For practice owners and administrators

A medical billing handoff starts before the new company submits its first claim. Someone still needs to answer for the claims already in flight, the denials nearing a deadline, and the payments that will arrive after the switch. Use this checklist to assign that work before the outgoing team signs off.

1. Map what the outgoing team still owns

Review the current agreement for the notice period, end date, reporting access, and any arrangement for working older accounts after termination. Record what the outgoing company will finish, what the incoming team will take over, and which decisions stay with the practice. If both teams will work at the same time, give each queue a clear owner and a date when ownership changes.

• New charges and rejected claims: agree on which team submits each batch and who corrects rejections that come back after the switch.
• Claims already with payers: assign follow-up, corrected claims, appeals, and requests for documentation.
• Remittances and balances: assign payment posting, reconciliation, and follow-up on any payments tied to pre-switch claims.

Write down which date or event determines ownership. A boundary based on date of service can leave a gap if one team assumes the other owns unsubmitted charges from earlier visits. Agree on how to handle exceptions before the changeover.

2. Capture an opening inventory and flag deadlines

Take a dated snapshot from the practice management system. Separate unbilled charges, clearinghouse rejections, payer-pending claims, denials, unposted remittances, and aging balances. For each urgent item, record the last action, next action, owner, deadline, and where the supporting records are kept. Reconcile counts and balances between the two teams using the same cutoff date and report filters.

Prioritize by the actual payer deadline and action required. Check the governing payer instructions for initial filing, corrected claims, appeals, and documentation requests. Those windows can differ. For an example of a deadline tied to a specific appeal stage, see the CMS guidance on first-level Medicare fee-for-service appeals.

Illustrative example. A denial has an appeal deadline in three business days, and the outgoing company drafted an appeal but has no submission confirmation. Assign one owner to verify status, complete any outstanding review, submit if appropriate, and save the payer acknowledgment. A draft in a work queue does not establish that the payer received it.

3. Verify systems and access before the switch

Have the practice's authorized administrator confirm who controls the EHR or practice management system, clearinghouse, payer portals, and electronic remittance access. Verify whether existing payer connections and remittance routing will continue with the new setup, and identify any enrollment changes or pending approvals. Use individually assigned access and document who will close the outgoing team's accounts when its work ends.

Agree on a secure way to transfer approved records and preserve reporting history. Confirm the applicable Business Associate Agreement (BAA) and safeguards before the incoming team receives access to protected health information (PHI). Review how the outgoing vendor will return, destroy, or safeguard any retained PHI under the applicable agreement. See HHS guidance on business associate contracts.

4. Check that the first claims and payments move

Once the new workflow is authorized, trace an agreed sample through the normal workflow. Match charges to submissions, verify acknowledgments, and check whether the payer accepted the claim for processing. When the first remittances arrive, confirm that they reach the right system and reconcile posted payments to deposits. Document any exceptions and their owner.

• First week: compare completed visits, charges entered, claims sent, payer acknowledgments, and unresolved rejections. Review approaching deadlines daily during the handoff.
• By day 30: compare the open queues with the starting inventory. Show what came in, what moved, what remains, and what is waiting on the practice or a payer. Track actions completed and payments received as separate measures.

Use the same definitions on each report so changes are comparable. The payment posting reconciliation checklist can help your team investigate mismatches, and the aging A/R guide covers how to prioritize older balances.

What to have in writing before you switch

• A handoff date and a named owner for each open queue, including items with imminent deadlines.
• An opening inventory, a plan for the first claims and remittances, and a backup owner if a connection fails.
• A secure access and offboarding plan, plus a date to review the first month with the practice.
