How likely is it that a probation officer would pull med records?

It's relatively uncommon for probation officers to pull medical records unless there is a specific reason related to the individual's case, such as verifying compliance with treatment programs or ensuring that medical conditions are considered in supervision. Generally, privacy laws like HIPAA restrict access to medical records without consent. If a probation officer believes that a probationer poses a risk to themselves or others due to a medical issue, they may seek records, but this typically requires legal justification.
