The SL modifier is NOT used for vaccines funded by the WVA for privately insured children under the age of 19.
The SL modifier is only used for publicly funded vaccines under the federal vaccines for children (VFC) program and the WA state Medicaid CHIP program for children under the age 19 which includes Medicaid, CHIP, uninsured, underinsured, and American Indian/Alaska Native.
While these vaccines are purchased and supplied by the WA state Department of Health at no cost to the provider or the patient, the vaccines are privately funded due to the dosage-based assessments (DBAs) which are charged to private payers and paid to the WVA.
