Consent to Receive Messages 
 

Patients provide written consent to receive SMS communications from Riverwalk Ambulatory  Surgery Center in connection with their care, surgical visit, or related operational  communications. 
 

Caregiver/authorized pickup contacts and authorized representatives receive messages only when  their contact information is provided by the patient and the patient authorizes such  communications. 
 

Authorized workflow participants receive workflow-only SMS notifications after:

• being provisioned an SIS Complete account by the ASC, and 

• voluntarily providing and opting in with their mobile number.
   

 

Message frequency may vary depending on patient activity, scheduled procedures, operational  workflow participation, and communication preferences. 

Two-Way Messaging 
 

Certain SMS messages may allow limited responses, such as: 

• appointment confirmations, 

• operational acknowledgments, or 

• brief care coordination communications. 
   

Two-way texting, when enabled, is limited to operational and healthcare-related purposes and  does not include marketing or promotional content.
 

Information Sharing and Disclosure 
 

Mobile information, SMS opt-in data, and text messaging consent information will not be shared  with third parties or affiliates for marketing or promotional purposes. 
 

All categories of information described in this Notice exclude text messaging originator opt-in  data and consent; this information will not be shared with any third parties except as necessary to  facilitate the secure delivery of SMS communications or as otherwise required by law. 
 

The ASC may utilize trusted service providers, vendors, and platform providers, including  Surgical Information Systems (SIS), solely for the purpose of supporting secure healthcare  communications, operational workflows, and related services. 
 

Security 
 

SMS communications are facilitated through secure systems and controlled workflows designed  to support patient privacy and operational security. 
 

Links delivered through the SIS Complete system utilize the secure siscomplete.cloud domain  and ASC-specific subdomains. Certain communications may also include secure links to  authorized billing or statement portals operated by trusted vendors. 
 

Because SMS is not always a fully encrypted method of communication, patients should avoid  sending sensitive personal, financial, or medical information through text message unless  specifically directed through a secure authenticated portal. 
 

Opting Out 
 

Recipients may opt out of SMS communications at any time by replying STOP to a message,  where supported, or by contacting the ASC directly.

 

Operational workflow recipients may also manage SMS notification preferences within their SIS  Complete account settings, where applicable.
