2025 ICD-10-CM code Z92

Personal history of medical treatment.

A corresponding procedure code must accompany a Z code if a procedure is performed. Z codes are used when circumstances other than a disease, injury, or external cause are recorded as diagnoses or problems.These circumstances may include limited care for a current condition, organ or tissue donation, prophylactic vaccination, or discussion of a problem not classifiable as a disease or injury.They may also represent a circumstance or problem influencing health status but not currently an illness or injury.

The medical necessity of this code is to provide context for a patient's current health status or future treatment needs based on their history of medical treatment.It's not typically used as a primary diagnosis but rather as supplementary information.

Clinicians use this code to document a patient's history of medical treatments, which may be relevant to their current health status or future care. It is important to use this code in conjunction with a procedure code if a procedure is performed. The code helps provide context for current conditions and can influence treatment decisions.

In simple words: This code indicates that you have a history of receiving medical treatment.

This code signifies a past history of medical treatment.It is used to document a patient's prior experience with medical interventions, which may influence current or future healthcare decisions.This code excludes post-procedural states (Z98.-).

Example 1: A patient presents for a routine check-up and mentions a history of long-term steroid use. The Z92.24 code (Personal history of steroid therapy) is used to document this history., A patient with a history of blood clots is scheduled for surgery. The Z92.1 code (Personal history of long-term (current) use of anticoagulants) is used to alert the surgical team to the potential bleeding risk., A patient being evaluated for a new condition reports past drug therapy that may be relevant. Z92.2 (Personal History of Drug Therapy) would be used to record this information.

Documentation should specify the type of medical treatment received. More specific Z92 codes should be used if applicable (e.g., Z92.1 for anticoagulant use, Z92.24 for steroid therapy). If the treatment is for a specific condition, that condition should also be coded.

** Excludes2: postprocedural states (Z98.-)
