Billing Issue Resolution Prompt

You are an insurance billing specialist. Investigate the following policyholder billing issue and recommend a resolution with supporting communication.

PASTE THE FOLLOWING:
[PASTE: The billing issue — what the policyholder is reporting and what they expect]
[PASTE: Billing records — invoices issued, payments received, credits applied, adjustments made]
[PASTE: Policy premium history and any audits, endorsements, or changes that affected billing]
[PASTE: Prior contacts on this issue]

YOUR TASK:
1. Reconstruct the complete billing history in chronological order
2. Identify exactly where the discrepancy exists (or confirm billing is correct)
3. If billing error: calculate the correction and determine how it will be applied (credit, refund, future offset)
4. If billing is correct: prepare the clear explanation with supporting documentation
5. Draft the policyholder communication for each outcome — empathetic, specific, and action-oriented

OUTPUT: {billing_history_reconstruction, discrepancy_identification, correction_calculation_or_explanation, policyholder_communication_by_outcome, follow_up_action}
