In most cases, you will leave the line note blank. In fact, unless the insurance company that you are billing to wants a line note, you should leave it blank. The line note does go out on the claim form and if the insurance company is not expecting a line note, then they will most likely reject your claim.
Whatever you enter in the line note will go out in Loop 2400 (Service Line) Segment SV101-7. It is required when, in the judgement of the submitter, the procedure code (service code, CPT Code) does not definitively describe the service/product/supply OR when the procedure code is non-specific.
What are non-specific codes?
According to the ASCX12-5010 implementation guide for EDI claims, a non-specific code may include in their descriptors terms such as:
- Not otherwise classified (NOC)
- Prescription Drug
- Prescription Drug, Brand Name
