Repriced CPT Code 64550

Understanding CPT Code Repricing in No-Fault Insurance Claims

In New York no-fault insurance law, insurance carriers frequently reprice medical procedures using different CPT codes than those originally billed by healthcare providers. This practice involves substituting a billed CPT code with what the carrier considers a more appropriate code, often resulting in lower reimbursement rates. The case of Compas Med., P.C. v 21st Century Ins. Co. illustrates how courts evaluate the validity of such repricing decisions.

CPT code 64550 typically refers to nerve injection procedures, while CPT code 97014 relates to electrical stimulation therapy. When carriers reprice from one code to another, they must demonstrate that the repricing aligns with the actual services provided and complies with applicable fee schedules. This repricing strategy is part of broader fee schedule enforcement mechanisms that carriers use to control costs while ensuring appropriate reimbursement for legitimate medical services.

The Legal Framework for CPT Code Repricing in New York No-Fault Cases

Repricing represents one of the most contentious issues in no-fault litigation. Healthcare providers bill using CPT codes they believe accurately describe the services rendered, while insurance carriers review those billings and may determine that different codes more appropriately capture the actual procedures performed. This creates inherent tension: providers argue they are entitled to reimbursement based on their professional judgment about appropriate coding, while carriers assert they have both the right and the obligation to ensure billings reflect actual services provided.

The workers’ compensation fee schedule, which New York no-fault insurers frequently use as a basis for reimbursement rates, assigns specific reimbursement amounts to each CPT code. Some codes command substantially higher reimbursement than others, creating significant financial implications when carriers reprice procedures. For example, nerve injection procedures (CPT 64550) typically reimburse at higher rates than electrical stimulation therapy (CPT 97014), making the distinction between these codes material to both parties.

Courts evaluating repricing disputes must balance competing concerns. Providers deserve fair compensation for services actually rendered, and carriers should not be able to arbitrarily reduce legitimate billings through improper repricing. However, carriers also have legitimate interests in preventing overbilling and ensuring that reimbursement rates correspond to actual services provided. When carriers can demonstrate through admissible evidence that repricing was proper, courts will uphold reduced payments even when providers object.

Case Background: Compas Medical v. 21st Century Insurance

In Compas Medical, P.C. v. 21st Century Insurance Co., a healthcare provider billed services using CPT code 64550, which typically applies to nerve injection procedures requiring physician expertise and involving more complex techniques. 21st Century Insurance repriced the services to CPT code 97014, which applies to electrical stimulation therapy—a significantly different type of treatment commanding lower reimbursement under the fee schedule.

Compas Medical challenged the repricing, presumably arguing that the services actually performed were nerve injections properly coded as 64550, not electrical stimulation therapy. The provider likely contended that 21st Century’s repricing was arbitrary or not supported by the medical records. The case proceeded to summary judgment, where the carrier sought dismissal based on its assertion that it had properly paid for the services under the workers’ compensation fee schedule after appropriate repricing.

Jason Tenenbaum’s Analysis:

Compas Med., P.C. v 21st Century Ins. Co., 2017 NY Slip Op 51228(U)(App. Term 2d Dept. 2017)

“Contrary to plaintiff’s further argument, defendant’s proof was sufficient to demonstrate, prima facie, that defendant had fully paid for the services charged under code 64550 of the workers’ compensation fee schedule”

I am sure the carrier repriced 64550 to 97014. The Court held, with an affidavit, the repricing was proper.

Legal Significance: Evidentiary Standards for Repricing Defenses

The Compas Medical decision reinforces that insurance carriers can successfully defend repricing decisions when they provide sufficient documentary evidence demonstrating compliance with applicable fee schedules. The key phrase in the court’s analysis—“defendant’s proof was sufficient to demonstrate, prima facie”—highlights that carriers must meet evidentiary burdens when asserting repricing defenses at summary judgment.

While the court’s brief analysis doesn’t detail exactly what proof 21st Century submitted, the reference to an affidavit suggests the carrier provided sworn testimony explaining the basis for repricing. This likely included analysis of the medical records, explanation of why the services actually performed corresponded to CPT 97014 rather than 64550, and demonstration that payment under the repriced code satisfied the carrier’s obligations under the workers’ compensation fee schedule.

The decision illustrates an important principle: repricing is permissible when carriers can substantiate their coding decisions through admissible evidence. Providers cannot defeat repricing simply by pointing to the CPT codes they used in their original billing. Instead, providers must demonstrate that the original coding accurately reflected the services performed and that the carrier’s repricing was incorrect as a matter of medical coding standards or fee schedule application.

This creates practical challenges for providers challenging repricing decisions. Providers must often retain coding experts who can review medical records and testify that the original CPT codes were appropriate. Without such expert testimony, providers may struggle to create triable issues of fact sufficient to defeat carriers’ summary judgment motions based on repricing.

Practical Implications: Documentation and Coding Best Practices

For healthcare providers, Compas Medical underscores the importance of detailed documentation supporting CPT code selection. When billing for nerve injection procedures under CPT 64550, providers should ensure medical records clearly document the injection technique, anatomical location, medications injected, and medical necessity for the specific procedure performed. This documentation should differentiate nerve injections from other modalities like electrical stimulation that command lower reimbursement.

Providers should also anticipate potential repricing challenges during the claims submission process. When billing procedures that might be confused with lower-reimbursement alternatives, providers can include explanatory notes or documentation with their initial claim submissions, reducing the likelihood that carriers will reprice the services or providing evidence to challenge repricing if it occurs.

For insurance companies, the decision confirms that proper repricing can be defended at summary judgment when supported by adequate evidence. However, carriers should ensure their repricing decisions are made by qualified personnel with coding expertise and are documented through contemporaneous file notes explaining the basis for the repricing. When repricing is challenged in litigation, carriers should retain qualified coding experts who can provide affidavits or testimony supporting the repricing decision.

The tension between provider billing autonomy and carrier repricing authority will continue to generate litigation in the no-fault system. As courts continue to address these disputes, clear documentation and expert support will remain essential for both sides.

Key Takeaway

This decision reinforces that insurance carriers can successfully defend repricing decisions when they provide sufficient documentary evidence, such as affidavits, demonstrating compliance with applicable fee schedules. Healthcare providers challenging repricing must be prepared to counter the carrier’s prima facie showing with compelling evidence that the original CPT code was appropriate for the services rendered.

Legal Update (February 2026): Since this 2017 post, New York’s no-fault fee schedules and CPT code reimbursement rates have likely been subject to multiple regulatory updates and amendments. Practitioners should verify current fee schedule provisions, repricing protocols, and any changes to acceptable CPT code substitution practices under current New York Insurance Department regulations.
