A medical canvass is an investigative process in which a licensed private investigator contacts healthcare providers, clinics, pharmacies, or other medical facilities in a defined geographic area to determine whether a subject has received treatment relevant to an insurance claim. The goal is to identify undisclosed medical visits, pre-existing conditions, or inconsistencies between claimed injuries and actual medical history.
A medical canvass involves an investigator reaching out to hospitals, urgent care centers, and similar facilities near a claimant's home or workplace to ask whether that person has been a patient there. This helps insurers determine if a claimant has a history of injuries that were not disclosed, or if they sought treatment that contradicts the timeline of an accident. The process can surface information that changes how a claim is evaluated.
A workers' compensation insurer suspects a claimant had a prior back injury before the reported workplace accident, and wants to know if that person sought treatment at nearby facilities before the claim date. In a personal injury case, an attorney needs to verify whether a plaintiff received care for the same body part at a clinic not mentioned in their medical records. An insurance company reviewing a disability claim wants to confirm that a claimant's reported condition is consistent with treatment patterns in the local area.
Licensed private investigators can legally contact healthcare facilities and ask whether a subject is or has been a patient, though facilities are generally prohibited from confirming or disclosing protected health information under HIPAA without patient authorization or a valid legal process. In most cases, investigators document which facilities were contacted and how each responded, rather than obtaining actual medical records through a canvass. Jurisdictional rules vary, and any retrieval of actual records typically requires a signed authorization, subpoena, or court order.
How long does a medical canvass typically take to complete, and what documentation will I receive at the end?
The timeline depends on the geographic scope and the number of facilities contacted, but most canvasses covering a regional area are completed within one to two weeks. At the conclusion, clients typically receive a written report listing every facility contacted, the date of contact, and the response received from each location. This report is formatted to be usable in legal or claims proceedings.
If a facility refuses to confirm or deny a patient relationship, does that make the canvass pointless?
Not necessarily. The investigator documents each response, including refusals, which can still be relevant when building a broader picture of a claimant's behavior or when combined with other investigative findings such as surveillance or activity checks. A pattern of refusals from facilities in a specific area, paired with other evidence, can prompt additional follow-up steps like requesting records through formal legal channels. The canvass itself creates a documented record of the investigative effort taken.
