What is the difference between a routine screening test versus a diagnostic test?
Routine screening tests are for patients without symptoms. Examples include a colonoscopy screening beginning at age 45, or a mammogram beginning at age 40. Routine screenings are covered as preventive with no member cost-sharing, per the ACA.
A diagnostic test is for patients with symptoms, or when an abnormality is found in patients without symptoms. You might receive a bill for a diagnostic test. A routine screening can become diagnostic in some situations. For example, you may schedule a routine colonoscopy screening and have no concerning symptoms to report. However, during your colonoscopy your doctor finds a polyp that is subsequently removed and sent to pathology for further testing. You may then be responsible for member cost-sharing for the removal and testing of the polyp that was found during your colonoscopy.
Before a procedure that involves anesthesia (drugs that may make you sleepy or unconscious), you will go through a consent process. This is where a doctor or care provider explains the procedure, the risks of the procedure, and may also explain that the screening procedure could become diagnostic. If you have questions, you can ask your doctor or the person going over paperwork with you. If you don’t understand, or aren’t sure, you are always allowed to ask more questions. It is the doctor or health care provider’s job to make sure you understand what you are signing.
