Healthcare providers or institutions may require a patient to sign certain forms related to the treatment or payment process (like consent forms for treatment or payment authorization), but these forms cannot waive the patient's fundamental rights under HIPAA. If a patient feels coerced into signing anything, they can refuse or ask for clarification before signing. If they don't want to sign, it shouldn't prevent them from receiving care, although certain administrative procedures (like billing or insurance claims) might be impacted.
