A medical practice receives a letter from a commercial payer’s Special Investigations Unit requesting charts, billing data or staff interviews. The letter may reference potential fraud, waste or abuse, but it is still necessary to determine the exact contractual relationship, scope of request and administrative stage. Assuming the inquiry is either harmless or an already-proven criminal accusation can lead to poor decisions. If the payer also seeks an interview, see the separate guide to commercial payer SIU interview requests and provider rights.
Read the network agreement and the actual notice
Identify who issued the request, the provider and tax ID involved, dates of service, stated concerns, requested records and claimed contractual authority. Network contracts may contain audit, cooperation, appeal, recoupment and termination provisions. The letter’s response deadline should be recorded with its transmission and receipt information.
Separate a payer’s internal SIU inquiry from a subpoena or formal government investigation. The legal obligations and consequences may differ, even if the same underlying claims eventually draw multiple reviewers.
Reconstruct the claims being questioned
Create a claim-by-claim inventory connecting billed services, orders, chart support, medical necessity, authorization, referrals and remittances. A practice’s electronic claim history may not reveal the underlying clinical decision, while a narrative clinical chart may not explain a particular billing modifier or adjustment.
Do not supplement records as though later-created explanations existed at the time of care. Clarifying statements may be appropriate, but original documentation should be preserved and accurately described.
Prepare carefully for requests to interview staff
An interview request raises questions about who the payer seeks to question, what contractual cooperation is required, how notes or recordings will be handled and whether counsel should participate. Employees may have personal interests distinct from the organization. A practice should not coordinate false accounts or pressure staff to adopt a preferred narrative.
A focused written response may clarify misunderstandings before an interview, but counsel should choose the approach based on the notice and contract rather than a categorical refusal or automatic agreement.
Address financial exposure and care continuity
Payment holds, offsets and network participation threats can affect an entire practice. Identify current financial action separately from the documentary inquiry. If the payer has asserted an overpayment, reconcile the amount and determine what administrative or contractual remedies are available.
The impact on patients and access to care can be relevant factual context, but it does not replace the need to answer claim-level allegations.
Information to organize
- SIU letter, attachments and the network agreement
- Full claims and remittance records for questioned services
- Clinical notes, orders, authorizations and billing policy
- Prior payer communications and audit history
- Interview requests and deadlines
