Short answer: A medical billing transition usually requires a planned period for access, enrollment, interfaces, testing, open claims and reporting; timing varies with payer and system dependencies.
Build the transition around dependencies
The calendar should account for payer enrollment, clearinghouse setup, EHR or practice-management access, data transfer, bank and ERA configuration, staff training and ownership of older balances.
Run parallel checks
Validate provider, location, payer and fee-schedule records before the first live batch. Reconcile encounters to claims and claims to acknowledgments so missing transactions are found early.
Protect work already in progress
Decide who will work open claims, denials, refunds and patient balances during the change. Keep exports and reports from the former arrangement accessible for reconciliation and audit needs.
