2025 ICD-10-CM code Z92.2

Personal history of drug therapy.This code indicates a past history of medication use, excluding current or long-term therapy.

Z codes, including Z92.2, should only be used as secondary diagnoses when a procedure code is also reported for a specific procedure performed during the encounter.

Medical necessity for coding Z92.2 is established when a physician needs to know about a patient's past medication use for reasons such as assessing potential drug interactions, medication allergies, or the impact of past therapies on current health status.It usually appears with a procedure code.

Documentation of a patient's past medication use is typically the responsibility of the physician or other qualified healthcare professional who is familiar with the patient's medical history. This might involve review of previous medical records, patient interview, or other relevant documentation to accurately reflect the patient's prior exposure to medication therapies.

IMPORTANT Related codes include Z92.21 (Personal history of antineoplastic chemotherapy), Z92.22 (Personal history of monoclonal drug therapy), Z92.23 (Personal history of estrogen therapy), Z92.24 (Personal history of steroid therapy), Z92.25 (Personal history of immunosuppression therapy), and Z92.29 (Personal history of other drug therapy).Note that Z79.- codes are used for long-term (current) drug therapy, and should not be used in conjunction with Z92.2.

In simple words: This code means the person has taken medicine in the past, but isn't taking it now.It's used when a doctor needs to know about medicines a person took before, but not for any medicines they are currently taking.It will be used along with other codes when the person has had a specific procedure done.

Z92.2, Personal history of drug therapy, is an ICD-10-CM code used to document a patient's past use of medications.This code is applied when the patient has a history of drug therapy, but is not currently receiving that therapy, or does not have a history of long-term (current) drug therapy.It is crucial to note that this code is used to document the past use of drugs and does not reflect current or ongoing drug regimens.The code should only be used if a specific procedure is performed and a related procedure code is included.This code excludes long-term (current) drug therapy (Z79.-) and postprocedural states (Z98.-).

Example 1: A 65-year-old male patient presents for a routine physical examination. During the history, he mentions that he was treated for hypertension with Lisinopril 10 years ago but has been off medication since then. Z92.2 would be appropriate to document this past drug therapy., A 40-year-old female patient is undergoing a surgical procedure.Review of her medical history indicates past treatment with chemotherapy for breast cancer 5 years prior. Z92.21 (Personal history of antineoplastic chemotherapy) would be used in addition to Z92.2., A 28-year-old patient with a history of asthma presents for a routine check-up. She mentions that she used an inhaled corticosteroid for her asthma 10 years ago, and hasn't used it since. Z92.240 (Personal history of inhaled steroid therapy) would be used in addition to Z92.2.

Documentation should include details such as the specific medication(s) used, the dates of therapy, and the reason for the medication use.This information can be obtained from the patient's medical records, patient interview, or other relevant documentation.

** Z92.2 should not be used if the patient is currently receiving long-term drug therapy. In such cases, the appropriate Z79.- code should be used instead.
