Top Medical Billing Audit Companies in the USA, 2026

A medical billing audit reviews the processes that affect reimbursement, including claim submission, insurance verification, coding, modifiers, denials, payment posting, accounts receivable, and payer follow-up. Persistex’s free billing audit also examines denial patterns and revenue opportunities. The goal is to identify where claims are being delayed, underpaid, denied, or never pursued so the practice can prioritize meaningful improvements.

An audit can expose recurring issues that quietly reduce collections, such as unsupported coding, missed modifiers, incomplete authorizations, delayed charge entry, or unworked denials. Once identified, these issues can be corrected through workflow changes, staff guidance, coding improvements, and focused A/R follow-up. Persistex reports outcomes including 40% fewer denials, 32% average collections growth, and A/R reductions from 90 to 30 days.

Yes. Persistex offers a complimentary billing audit with no obligation, no hidden fees, and no contract requirement. The review covers the current billing process, denial patterns, and revenue opportunities. After an online request, a billing specialist responds within 24 hours during the Monday-through-Friday business schedule to arrange the review. Practice information is handled through HIPAA-compliant operations and is never shared.

A billing audit examines the broader claims and payment workflow, including denials, A/R, payer follow-up, and collection performance. A coding audit concentrates on the clinical documentation and code selection behind a claim, such as CPT, ICD-10, HCPCS, E/M levels, and modifiers. Together, these reviews can identify whether reimbursement issues originate before submission or later in the revenue cycle.

Billing audits can help practices of every size, from solo providers to organizations with 15 or more clinicians. Persistex works with behavioral health, TMS therapy, psychiatry, family medicine, internal medicine, primary care, pediatrics, chiropractic, podiatry, and other outpatient practices. Reviews are especially helpful when denials rise, A/R ages, collections feel inconsistent, or a practice is evaluating its current billing arrangement.

Yes. Behavioral health and TMS billing often involves payer-specific requirements for time-based services, session limits, telehealth, authorizations, modifiers, and specialized CPT codes. Persistex has focused expertise in these areas, including TMS codes 90867 through 90869. An audit can assess whether documentation, coding, authorization tracking, and appeals processes are supporting accurate reimbursement and reducing avoidable denials.

The timeline depends on the volume and accessibility of billing, claims, and reporting data, but the first step is prompt: a Persistex billing specialist responds within 24 hours on business days after a request is submitted. The audit is then scheduled around the practice’s availability. Findings focus on actionable issues, allowing practices to understand priority revenue opportunities without a lengthy commitment process.

No. A billing audit does not require a practice to switch vendors or sign a long-term contract. It can be used to understand current performance, investigate a specific concern, or evaluate potential revenue leakage while under another billing agreement. Persistex can also provide transition assistance when a practice decides it is ready to change its billing or revenue-cycle management support.
