Does health insurance cover diagnostic charges like X- ray, MRI or ultrasound?

If you are hospitalized, then charges for X- ray, MRI or ultrasound are payable provided these are required for the treatment for which you are admitted. If these tests are conducted within 30 days prior to Hospitalization and lead to diagnosis for which you are admitted for curative treatment then this is also payable. If any of these tests are conducted and are not relevant to the treatment then these are not payable.
