Personal history of gene therapy

This code signifies that a patient has previously undergone gene therapy. It indicates a historical medical intervention where genetic material was introduced into a person's cells to treat or prevent disease. This history is relevant for ongoing patient management, potential long-term follow-up, and assessing future treatment options.

Use this code when documenting a patient's past medical history that includes receiving gene therapy. This applies to patients presenting for follow-up care, new conditions, or when their historical treatments need to be captured in their medical record for comprehensive care planning. It is a secondary diagnosis, not a primary reason for an encounter.

• Always assign this code as a secondary diagnosis to provide additional information about the patient's medical history.
• Do not use this code for patients currently receiving gene therapy; instead, use codes for the specific gene therapy procedure and any associated complications.
• Ensure the medical record clearly documents the prior receipt of gene therapy to support the use of this code.
