  • CPT codes 64643 and 64645 are classified as add-on codes, ie, codes describing a service performed in conjunction with a primary service. An add-on code is eligible for payment only when reported with an appropriate primary procedure performed by a single provider. CPT codes 64643 or 64645 must never be reported as a stand-alone code

Disclaimer: Merz has developed the XEOMIN coding and billing information to provide a general overview of coverage, coding, and claim submission information relevant to XEOMIN and associated services. This summary is intended solely for educational purposes. Information should not be construed as legal advice nor is it advice about how to code, complete, bill, or submit any particular claim for payment. It is important to check with the health plan directly to confirm coverage for individual patients. This coding and reimbursement information is subject to change and may be outdated. Merz disclaims any responsibility for claims submitted by providers or physicians and does not guarantee that payors will consider all codes appropriate for all encounter scenarios or that coverage and reimbursement will result. The key in all coding and billing to payors is to be truthful and not misleading and make full disclosures to the payor about the product and the procedures associated with its use when seeking reimbursement for any product or procedure. It is the provider’s and physician’s responsibility to determine appropriate codes, charges, and modifiers, and to submit bills for services and products consistent with what was rendered, as well as the patient’s insurer requirements. Third-party payors may have different coverage and reimbursement policies and coding requirements. Such policies can change over time. Providers are encouraged to contact third-party payors for each patient to verify specific information on their coding policies.
