What is a service type code?

ServiceType codes are used to identify business groupings for healthcare services and benefits. Includ the serviceType in the Care Cost Estimator API request body, and then submit to payers on an eligibility and benefit inquiry transaction to get patient’s eligibility and benefit details for out-of-pocket cost estimate. The serviceType code consists of value and valueType. An example:

"service": {
    "codes": [
        "value": "98",
        "valueType": "ServiceTypeCode"

Each payer may have different supported service types for eligibility and benefit inquiries. You may visit individual payer site to find supported serviceType codes and the serviceType code best to use for the procedure you or your patients are trying to get an estimate of out-of-pocket cost. We recommend you purchase and use the 270 Implementation Guide specs.
List of serviceType codes you can find on Connect Center >> under Verification >> Start New Eligibility Request >> drop-down list under ‘Service Information’ >> Service Type.

If you are not sure what service type code to use, you can use serviceType code “30” for a general Health Benefit Plan Coverage inquiry. Here is a list of official list from the x12 org.
