Coding information

Hospital Inpatient Setting

Medicare Inpatient Coding and Payment (Part A) This information details our general understanding of the application of certain codes to ANDEXXA. It is the provider’s sole responsibility to determine the appropriate codes for any action taken in billing. This information is not intended to be definitive or exhaustive, and Alexion makes no warranties or guarantees as to the accuracy or appropriateness of this information. Before filing any claim, providers should verify these requirements with specific payers.
  • Only one Medicare Severity-Diagnosis Related Group (MS-DRG) is assigned to a patient for a particular hospital admission, and determined by ICD-10-CM diagnoses and procedure codes.
    • Patients who received ANDEXXA during their hospital stay may be assigned to different MS-DRGs based on these variables.
  • Effective Oct. 1, 2016, there are two unique ICD-10-PCS procedure codes that are applicable for the introduction of ANDEXXA.2
ICD-10-PCS Code Descriptor
Introduction of Andexanet Alfa, Factor Xa Inhibitor Reversal Agent into Peripheral Vein, Percutaneous Approach, New Technology Group 2
Introduction of Andexanet Alfa, Factor Xa Inhibitor Reversal Agent into Central Vein, Percutaneous Approach, New Technology Group 2
ANDEXXA (coagulation factor Xa (recombinant), inactivated-zhzo) is also referred to by the US adopted name (USAN) of andexanet alfa.

Medicare New Technology Add-on Payment (NTAP)

Medicare coverage is available for ANDEXXA. Centers for Medicare & Medicaid Services (CMS) increased New Technology Add-on Payments (NTAPs) in fiscal year 2020 to promote patient access and reimbursement confidence for “new” and “transformative technologies.” An NTAP provides additional payment to hospitals above the standard Medicare Severity Diagnosis-Related Group (MS-DRG) payment amount.2†

NTAP reimbursement for this product has been renewed until September 30, 2021.3

Commercial Reimbursement

Commercial health plan reimbursement may vary. Many plans follow Medicare reimbursement guidance.4‡

Payers may vary on timing.

Eligibility to receive add-on payments may vary. Hospitals not reimbursed under the IPPS are not eligible to receive add-on payments

Hospital Outpatient Setting

Standardized code for ANDEXXA insurance claims across Medicare, Medicare Advantage, Medicaid and commercial plans

Effective July 1, 2020, the Centers for Medicare and Medicaid Services (CMS) has granted ANDEXXA its permanent J-code, facilitating reimbursement in all hospital outpatient departments and freestanding emergency facilities in the United States.5

Hospitals and physicians are responsible for compliance with Medicare and other payer rules and requirements and for the information
submitted with all claims and appeals. Before any claims or appeals are submitted, hospitals and physicians should review official payer
instructions and requirements, should confirm the accuracy of their coding or billing practices with these payers, and should use independent
judgment when selecting codes that most appropriately describe the services or supplies provided to a patient.

HCPCS Code Brand Name HCPCS Description
Injection, coagulation Factor Xa (recombinant), inactivated-zhzo (ANDEXXA), 10 mg
For services on or after July 1, 2020§

§For ANDEXXA claims for dates of service before July 1, 2020, hospitals must bill for ANDEXXA using its unique HCPCS C-code, C9041, to be eligible for pass-through payment. For payers who do not accept C-code claims before July 1, 2020, institutions may bill the miscellaneous J-code, J3590, for ANDEXXA.6

Because coding and billing requirements may vary, providers should check with payers directly to verify the information needed for claims submission.
