Summary & Overview
HCPCS Level II J1808: Injection, Folic Acid 0.1 mg
HCPCS Level II code J1808 denotes a 0.1 mg folic acid injection, an injectable micronutrient used in clinical settings for prevention or treatment of folate deficiency. Nationally, this code matters because injectable folic acid is used in specific clinical scenarios—such as patients with malabsorption, certain hematologic conditions, or when enteral administration is not feasible—and accurate coding ensures appropriate coverage and claims processing across payers. Key payers included in this analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
Readers will learn the clinical context for use of J1808, typical sites of service, and how this HCPCS Level II code fits into billing workflows for injectable medications. The overview covers payer coverage patterns, common billing modifiers linked to injectable drug administration, and coding considerations that affect claim adjudication. The publication also outlines benchmarks and policy updates relevant to injectable medication coding and describes scenarios where parenteral folic acid is documented and billed. Data not available in the input is noted where payer-specific rates, utilization metrics, or associated taxonomies and ICD-10 mappings would normally appear.

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult or pregnant person with documented folate deficiency, megaloblastic anemia, or at increased risk for neural tube defects who requires parenteral folic acid administration. The patient presents to an outpatient infusion clinic, emergency department, or obstetrics clinic after laboratory confirmation of low serum folate or when oral administration is not tolerated (for example, persistent vomiting, malabsorption, or rapid correction need). The clinical workflow includes verification of indication and allergies, nursing preparation of the J1808 0.1 mg folic acid injection, patient consent, administration via intramuscular or subcutaneous route per facility policy, observation for immediate adverse reactions (typically 15–30 minutes), documentation of lot number and site, and discharge with follow-up instructions and any necessary oral supplementation plan or referral to primary care, hematology, or obstetrics.
