Personal history of other medical treatment

This code indicates a patient's past experience with medical treatments that are not specifically categorized elsewhere in the Z92 series. It signifies that a prior medical intervention, other than those with dedicated history codes, has occurred and may be relevant to the patient's current health status or future care.

Apply this code when documentation specifies a history of medical treatment such as phototherapy, hyperbaric oxygen therapy, or specific rehabilitation programs, where no more specific Z code exists. It is also appropriate for documenting a history of medical device implantation or removal that doesn't have its own dedicated history code.

• Always sequence this code as a secondary diagnosis, as it provides historical context rather than a current condition.
• Ensure the documentation clearly specifies the "other" medical treatment to justify its use over more specific history codes.
• Avoid using this code if a more precise Z code (e.g., Z92.2 for personal history of antineoplastic chemotherapy) is available for the documented treatment.
