Medical Coding Tip: How to Code RiaSTAP with HCPCS!
Coding RiaSTAP (fibrinogen concentrate, human)? This clotting factor replacement therapy is used to treat acute bleeding episodes in patients with congenital fibrinogen deficiency, including afibrinogenemia and hypofibrinogenemia.
HCPCS Code:
J7178 – Injection, human fibrinogen concentrate, not otherwise specified, 1 mg.
Billing Examples:
500 mg administered = 500 billing units
1,000 mg administered = 1,000 billing units
2,000 mg administered = 2,000 billing units
Important: RiaSTAP is administered intravenously, and HCPCS billing units are based on milligrams, not the number of vials used.
Coding Clarified Tip: RiaSTAP vials contain approximately 1 g or 2 g of fibrinogen, but actual potency can vary. Always check the vial's labeled potency, the amount administered, documentation, and payer requirements when calculating billing units.
Remember: One HCPCS J7178 billing unit represents 1 mg of human fibrinogen concentrate. Accurate dose conversion is essential for correct billing!
