Pre-payment review

Pre-payment review places a provider or facility in a mandatory documentation-submission workflow for every claim in a designated service category. Instead of the normal submit-then-pay sequence, the payer withholds adjudication until it has reviewed the underlying medical records and confirmed that the billed codes are supported by clinical documentation and meet medical necessity criteria. Two review subtypes exist: non-complex reviews, which rely solely on claim-level data edits such as National Correct Coding Initiative (NCCI) or Medically Unlikely Edits (MUEs), and complex reviews, which require full medical records, operative notes, or consultation reports before a payment decision is rendered.

Payers initiate pre-payment review for several reasons: a provider's error rate on prior post-payment audits exceeds acceptable thresholds, documentation has repeatedly failed to support the billed level of service, services have been found not to be medically necessary, or the provider's utilization pattern for a specific code—such as consistently high-level E/M visits or a high-volume arthroscopy code—deviates meaningfully from regional peers. CMS and its contractors use pre-payment review as a targeted integrity tool, while commercial payers apply analogous policies under their own contractual authority.

Resolving a pre-payment review designation requires a two-step approach. First, the practice must conduct an internal audit, confirm that all remaining and future claims are fully supported by documentation, and correct any systemic coding or documentation gaps. Second, the billing team engages the payer directly—presenting error-rate improvement data and requesting removal from the program. Providers retain appeal rights when a specific claim is adjusted or denied during the review period. Proactive steps—certified coders, pre-bill audits, and ongoing provider education on diagnosis specificity and medical necessity—are the most effective way to avoid triggering the process in the first place.

Being placed on pre-payment review directly delays cash flow for every affected claim, increases days in accounts receivable, and imposes significant unilateral administrative costs on the practice—not the payer. For orthopedic practices, where high-value procedures such as total joint replacements, arthroscopies, and fracture repairs are already subject to heightened scrutiny, even a short period on pre-payment review can materially disrupt revenue. Beyond the financial impact, the designation signals to payers—and potentially to CMS contractors—that a practice's billing practices warrant ongoing scrutiny, which can escalate into post-payment audits, overpayment demands, or referral to program integrity units if root causes are not corrected.
