J1745 CPT Code: Accurate Billing for Infusion Therapy

The J1745 CPT code is widely used in infusion therapy to report infliximab injection, a biologic commonly administered for autoimmune disorders. Proper use of this code is essential for accurate reimbursement and minimizing claim denials. Infusion practices can face significant challenges without clear guidance, which is where Infusion Billing Services helps streamline billing processes.

What Is the J1745 CPT Code?

The J1745 CPT code represents injection, infliximab, 10 mg. It is used to bill for infliximab administered via IV infusion in clinical settings. Accurate coding is critical because infliximab is a high-cost medication, and insurance payers scrutinize claims for medical necessity and documentation compliance.

Why Correct Use of J1745 Matters

Improper use of J1745 can lead to:

• 
  

  Claim denials

  
  


• 
  

  Delayed reimbursements

  
  


• 
  

  Audit risks

  
  

Using this code accurately ensures your infusion center is reimbursed fairly and avoids administrative delays.

Documentation Requirements

Proper documentation for J1745 CPT code includes:

• 
  

  Patient diagnosis: Ensure the primary ICD-10 code supports medical necessity

  
  


• 
  

  Medication details: Dose, lot number, and route of administration

  
  


• 
  

  Infusion details: Start and stop time, infusion duration, and any reactions

  
  


• 
  

  Physician notes: Justification for infliximab therapy

  
  

Incomplete or inaccurate documentation is one of the most common reasons claims for J1745 are denied.

Common Coding Errors

Infusion practices often make mistakes with J1745 due to:

• 
  

  Using the wrong dose unit

  
  


• 
  

  Not pairing J1745 with the correct ICD-10 diagnosis code

  
  


• 
  

  Missing documentation for infusion start and stop times

  
  


• 
  

  Confusing J1745 with other biologic or infusion codes

  
  

Avoiding these errors is key to reducing denials and improving revenue cycle efficiency.
