How to collect an unpaid medical or dental invoice
Short answer
Medical and dental billing is regulated more tightly than general business invoicing. HIPAA limits what you can disclose when following up, and many states have patient protection laws affecting collection timing and communication methods. Most practices use a specialized medical billing company or healthcare collections firm instead of a general-purpose approach. Not legal advice — consult a healthcare attorney.
Patient responsibility billing (copays, deductibles, amounts not covered by insurance) takes a different regulatory path than general business invoicing. HIPAA restricts how and with whom you can discuss a patient's account. Collection communications that would be standard practice in other industries can create HIPAA liability in a medical context. Practices doing meaningful volume on patient collections almost always work with a medical billing company or a healthcare-specific collections firm that has HIPAA-compliant workflows.
State law on timing matters more than in most industries. Several states have waiting periods before a medical bill can go to collections, and some require specific dispute-resolution processes to be offered to patients before escalation. The Affordable Care Act layered additional rules on nonprofit hospital billing to lower-income patients. The rules are not uniform and they change periodically.
For small healthcare practices, the practical path on overdue patient balances looks like this: a clear financial policy signed at intake, a two-statement billing cycle (30 days, then 60), a phone call from a billing coordinator around day 60, and a final notice at 90 days before referring to a healthcare collections firm. HIPAA-compliant patient payment portals that allow self-pay online lift collection rates significantly compared to paper billing.
B2B invoices to insurance companies or other healthcare payers are a different process entirely. Payer disputes go through internal appeals, not standard collections. The primary tools are persistence through the payer's appeals channels and escalation to state insurance commissioners for wrongful denials. Healthcare billing is specialized enough that for any significant disputed amount, a healthcare attorney or consultant pays for itself. Not legal advice.
