For minors, patient records must be kept until the age of:

In Iowa, the law stipulates that patient records for minors must be retained for a certain duration after they reach the age of majority, which is typically 18 years old. However, in the context of dental hygiene and healthcare records, the requirement is that records must be maintained for a minimum of three years after a patient turns 18 or until they reach the age of 19, whichever is longer.

This means that if a minor is treated and their records are created, those records must remain accessible until they are 19, as this extends beyond the standard age of legal adulthood in Iowa. This retention period ensures that healthcare providers have adequate documentation of the care provided, which may be pertinent for future medical, legal, or continuity-of-care purposes.

So, the correct answer reflects the requirement that records for minors must be maintained until they turn 19.
