2025 ICD-10-CM code Z92.25

Personal history of immunosuppression therapy.

This code should only be used when the history of immunosuppression is relevant to the current clinical encounter and accurately reflects the patient’s past medical history. It should not be the primary diagnosis unless the focus of the visit is specifically related to the consequences or management of the past immunosuppression.

No modifiers are typically applied to this code.

Medical necessity for this code is established through appropriate documentation of a past history of immunosuppression. This information is medically necessary because it influences the management of the patient's current condition and potential risks.Past immunosuppression can increase susceptibility to infections and other complications, necessitating a cautious approach to care.

The clinical responsibility for this code lies with the physician or other qualified healthcare provider who is documenting the patient's history of immunosuppressive therapy.They must ensure that the documentation accurately reflects the patient's past treatments and that the code is applied appropriately based on the clinical context.

IMPORTANT This code should not be used if the patient is currently undergoing immunosuppression therapy. In that case, codes from category Z79 (Long-term (current) use of drugs) might be more appropriate.Also, consider Z92.24 (Personal history of steroid therapy) if the immunosuppression was primarily due to steroids, and ensure you are using the most recent and accurate codes.

In simple words: This code means the patient has received treatment in the past to lower their body's natural defenses (immune system).This information is important for the doctor's understanding of the patient's medical history.

This code signifies a documented history of immunosuppression therapy.It is used to indicate that the patient has received treatment to suppress their immune system, regardless of the current status of that therapy. This code is used in situations where the past immunosuppression is relevant to the current encounter but does not represent the primary reason for the visit.

Example 1: A patient presents for a routine checkup.Review of their medical records reveals a history of immunosuppression therapy due to organ transplantation five years prior.Z92.25 is added to the record to document this relevant historical information, even though it's not the reason for the current visit., A patient is seeking treatment for a new infection.Their medical history includes a course of immunosuppressive therapy for an autoimmune disease completed last year.Z92.25 is used to reflect the past immunosuppression, which influences the diagnosis and treatment of the current infection., A patient with a history of cancer treatment, including chemotherapy and radiation, is being seen for a follow-up.The patient has completed their cancer therapy. The healthcare provider uses Z92.25 to document the prior use of immunosuppressive therapy, as it is relevant to their long-term health and potential risks.

Documentation should include the type of immunosuppression therapy (e.g., corticosteroids, chemotherapy, other immunosuppressants), the reason for the therapy, the dates of therapy, and any relevant adverse effects.Specific details of the therapy should be recorded in the patient's medical chart.

** Always ensure that the documentation supports the use of this code.Review current coding guidelines and consult with other healthcare professionals when there is uncertainty about proper coding practices.
