NC Medicaid to Cover Imported Benzathine Benzylpenicillin (Extencilline®) and Benzathine Benzylpenicillin Tetrahydrate (Lentocilin): Billing Guidelines

Effective with date of service Aug. 1, 2025, NC Medicaid covers benzathine benzylpenicillin (Extencilline®) and benzathine benzylpenicillin tetrahydrate (Lentocilin).

NC Medicaid will temporarily cover, effective for dates of service from Aug. 1, 2025, and limited to Food and Drug Administration (FDA) authorization for importation, the following presentations of imported benzathine benzylpenicillin (Extencilline®) and imported benzathine benzylpenicillin tetrahydrate (Lentocilin) for use in outpatient medical drug claims when billed with HCPCS code J0561 - Injection, penicillin G benzathine, 100,000 units and at outpatient pharmacy (point-of-sale).

Temporary coverage is being added to address the supply shortage of Bicillin® L-A (penicillin G benzathine injectable suspension) due to a product recall. NC Medicaid coverage of imported Extencilline® and Lentocilin will end when the product shortage has resolved. This applies to NC Medicaid Direct and NC Medicaid Managed Care.

The FDA recognizes this recall could cause challenges procuring enough Bicillin® L-A to meet providers’ needs. Extencilline® and Lentocilin are approved by the FDA for temporary importation due to product shortages. Please note that the preparation, administration and contraindications of Extencilline® and Lentocilin differ from those for Bicillin® L-A. A prescription is required for Extencilline® and Lentocilin in the United States.
