2025 ICD-10-CM code Z92.850

Personal history of Chimeric Antigen Receptor T-cell therapy.

Adhere to official ICD-10-CM coding guidelines and conventions. Use this code only when a documented history of CAR T-cell therapy exists.Avoid using this code if the patient received other forms of cellular therapy.

Modifiers are not typically applied to ICD-10-CM codes like Z92.850.

The medical necessity for coding Z92.850 is established by the presence of a documented history of CAR T-cell therapy. This history is clinically relevant for appropriate management of the patient's current health status.

The clinical responsibility for this code falls on the physician or healthcare provider managing the patient's overall care.This includes considering the patient's history of CAR T-cell therapy when making treatment decisions, ordering tests, and monitoring for potential long-term effects.

IMPORTANT Related codes include Z92.85 (Personal history of cellular therapy), Z92.858 (Personal history of other cellular therapy), and potentially Z92.89 (Personal history of other medical treatment) depending on the specific context.

In simple words: This code is used to note that a patient has had a type of advanced cancer treatment called CAR T-cell therapy in the past. This information is important for their current healthcare.

This code signifies a patient's documented history of receiving Chimeric Antigen Receptor (CAR) T-cell therapy.It's used to indicate a relevant past medical event that may influence current health status or treatment decisions, regardless of whether the patient is currently experiencing related symptoms or complications.The code is applied to reflect the impact of this prior therapy on the patient's overall health profile.

Example 1: A 55-year-old patient with a history of relapsed lymphoma who underwent CAR T-cell therapy two years prior presents for a routine follow-up appointment.The physician uses Z92.850 to document the patient's prior CAR T-cell therapy in the medical record and ensures appropriate monitoring for potential long-term effects., A 60-year-old patient with a history of multiple myeloma and CAR T-cell therapy six months ago is admitted to the hospital for a new infection. The code Z92.850 is used to document the prior CAR T-cell therapy, potentially influencing the treatment plan for the current infection., A 48-year-old patient being evaluated for a new diagnosis of leukemia has a history of CAR T-cell therapy ten years prior. This information, coded as Z92.850, is crucial to the diagnostic work-up and the selection of suitable treatment options.

Documentation should include the date(s) of CAR T-cell therapy, the type of CAR T-cell therapy administered, the indication for the therapy (diagnosis), and any complications or side effects experienced by the patient.Progress notes, treatment records, and pathology reports may be used to support the coding.

** Z92.850 is a valuable code for capturing a patient's history of CAR T-cell therapy, which is a complex treatment with potentially long-term implications for health. Accurate coding ensures appropriate reimbursement and contributes to comprehensive patient care.
