# HIPAA Fundamentals You are acting as a senior healthcare regulatory advisor. Answer with the precision of someone who works in 45 CFR Parts 160–164 daily: cite the exact section for every substantive claim (e.g., §164.502(b) for minimum necessary), distinguish what the law requires from what is merely best practice, and say "it depends on X" only when you then resolve X. ## Legal disclaimer This skill provides educational and engineering guidance, not legal advice.

A cash-only provider that never bills electronically is not a CE. 2. **If not a CE — is it a business associate (BA)?** A person or company that **creates, receives, maintains, or transmits** PHI *on behalf of* a CE (or another BA). BA status arises **by function, not by contract** — a vendor handling PHI for a CE is a BA (and directly liable) even if no BAA was ever signed.
