Care first. Seek urgent medical or dental attention for serious or worsening symptoms. Researching or preparing a complaint should never delay treatment.

Complaint instructions checked against the linked sources, with limitations and known conflicts. Confirm that the authority covers your concern.

Authority and scope

Check the facility type and concern

FLIS licenses and investigates Connecticut healthcare institutions. Its list includes hospitals and psychiatric hospitals, ambulatory surgical centers and outpatient clinics, nursing homes and residential care homes, assisted living service agencies, home health and hospice. Behavioral categories include psychiatric outpatient clinics for adults, substance-use treatment facilities, mental-health day treatment, residential living centers and community residences. Select the actual licensed entity and level of care.

Submission

How the official source says to file

  • Use FLIS Complaint Submission for concerns about treatment, care or services received or not received in a licensed facility. Anyone with knowledge of the concern may report; examples include neglect, unsafe conditions, inadequate staffing or poor care.
  • Complete the online form as fully as possible, including your contact details and names/phone numbers of people with whom you already filed a complaint. Prepare the facility name, patient or resident involved, dates and a factual account to help identify the concern.
  • Save the confirmation number provided after successful submission for follow-up. This guide does not establish that opening the form or contacting a help desk files a complaint.
  • For help with complaint submission, use FLIS’s linked help-desk ticket service. DPH also lists 800-828-9769 for its Hospice and Medicare Home Health complaint hotlines. Patient-record release, representative-authority and signature requirements were not established; ask before sending another person’s records.

Limits

What this route may not provide

An assisted living service agency is the listed licensed category; do not assume every housing or residence issue falls within that service license. DPH separately says ordinary doctor, counseling and therapy offices are not licensed as offices. Individual professional complaints use a different process. FLIS also performs federal certification for certain institutions, which is distinct from its state licensing role. Financial remedies and ordinary billing/insurance jurisdiction were not established.

Anonymity

Do not guess about confidentiality

The checked facility instructions request contact information but do not establish anonymous acceptance, identity protection from the facility or public-record treatment. Ask FLIS about these separately, especially when the report concerns a child, another adult or sensitive treatment records. Do not borrow the practitioner complaint form’s release rules.

Complaint timing

Ask promptly; filing deadline unverified

A filing deadline was not established by this check; ask promptly. No facility investigation completion target was established. Provider event-reporting obligations and consumer complaint deadlines are different questions.

Process

What may happen after filing

FLIS’s stated role includes investigating licensed-facility clinical care and services. Keep the complaint confirmation number and ask FLIS how to supply additional evidence, check status and obtain the outcome. The checked instructions do not promise a particular investigation result.

Evidence

Prepare a reviewable submission

State the concern you want reviewed, give a short chronology and factual consequences, and explain your request. Keep supporting records and follow the receiving authority’s instructions before attaching or sending them.

Other facility processes to consider

These processes have different purposes. The national guidance below does not establish this state’s filing requirements or change the verification level shown above.

Hospital grievance

For hospitals covered by CMS hospital Conditions of Participation, ask for the grievance contact and written procedure. The hospital must specify response timeframes and give a written decision describing its contact, investigation, results and completion date. These are hospital rules, not a single rule for every facility. You may contact the responsible State Survey Agency without first completing the hospital process.

Supporting guidance: CMS: hospital grievance guidance

State oversight

Match external oversight to the facility type and license. State Survey Agencies help CMS assess federal compliance; state licensing may cover different settings. Confirm jurisdiction rather than assuming one contact handles every clinic or residential program.

Supporting guidance: CMS: State Survey Agency contacts

Medicare quality review and appeals

People with Medicare can ask their Medicare quality-review organization (BFCC-QIO) about eligible quality-of-care concerns. A complaint is different from a fast appeal when discharge or covered services may be ending too soon. Follow the Important Message from Medicare or Notice of Medicare Non-Coverage immediately; the notice identifies the contact and deadline. A routine grievance does not substitute for that appeal.

Supporting guidance: Medicare: fast appeals and BFCC-QIO help

Long-term-care advocacy

Long-Term Care Ombudsmen advocate for residents of nursing homes, assisted living and similar residential settings. They help resolve concerns according to the resident’s wishes; they are not licensing enforcement. Identity disclosure generally requires informed consent, with court-order and specified incapacity exceptions. Ask how resident, representative and complainant consent applies.
