Sounds as if in your case the refusal was simply given due to the missing medical results (not as a result of INA 221(g) refusal with the requisite DS-5535 submission), and that once medicals were received and approved, the visa was adjudicated.
The Congressional Inquiries (two done in my case so far), have very little impact for those of us in AP due Security Advisory Opinion (SAO) review, commonly called "security clearance," "administrative clearance," or "administrative processing," refusals.
