Code: Z79.899
Code Name: ICD-10 Code for Other long term (current) drug therapy
Block: Persons with potential health hazards related to family and personal history and certain conditions influencing health status (Z77-Z99)

Code also any follow-up examination (Z08-Z09)

Details: Other long term (current) drug therapy

Code also: any therapeutic drug level monitoring (Z51.81)

Includes: long term (current) drug use for prophylactic purposes

Excludes2: drug abuse and dependence (F11-F19)
drug use complicating pregnancy, childbirth, and the puerperium (O99.32-)

long term (current) use of oral hypoglycemic drugs (Z79.84)"
Guidelines: Factors influencing health status and contact with health services (Z00-Z99)

Note: Z codes represent reasons for encounters. A corresponding procedure code must accompany a Z code if a procedure is performed. Categories Z00-Z99 are provided for occasions when circumstances other than a disease, injury or external cause classifiable to categories A00-Y99 are recorded as 'diagnoses' or 'problems'. This can arise in two main ways:
(a) When a person who may or may not be sick encounters the health services for some specific purpose, such as to receive limited care or service for a current condition, to donate an organ or tissue, to receive prophylactic vaccination (immunization), or to discuss a problem which is in itself not a disease or injury.
(b) When some circumstance or problem is present which influences the person's health status but is not in itself a current illness or injury.

Does anyone please help me about the Long term drug use guideline? Is it necessary the drug should be there in the patients home medication list(Past medication) and that should be continuing after discharge from the hospital also. OR this long term drug code can be used for a drug which has been prescribed during hospital visit and asking to continue for an unlimited period.

Long term (current) drug use - V58.6 codes are for use for when the patient has been on a medication for an extended time, or when the medication has been currently prescribed with the intent of long term use.

Z79 is the category for long term(current) drug use. The individual drugs have a different code in this category and other drugs is at the end. This is the same as the V58.6 category in ICD-9

ICD-10-CM Official Guidelines - Z79 Long-term (current) drug therapy

Z79 Long-term (current) drug therapy

Codes from this category indicate a patient’s
continuous use of a prescribed drug (including such
things as aspirin therapy) for the long-term treatment
of a condition or for prophylactic use. It is not for
use for patients who have addictions to drugs. This
subcategory is not for use of medications for
detoxification or maintenance programs to prevent
withdrawal symptoms in patients with drug
dependence (e.g., methadone maintenance for opiate
dependence). Assign the appropriate code for the
drug dependence instead.
Assign a code from Z79 if the patient is receiving a
medication for an extended period as a prophylactic
measure (such as for the prevention of deep vein
thrombosis) or as treatment of a chronic condition
(such as arthritis) or a disease requiring a lengthy
course of treatment (such as cancer). Do not assign a
code from category Z79 for medication being
administered for a brief period of time to treat an
acute illness or injury (such as a course of antibiotics
to treat acute bronchitis).
