Code: Z79.01

Code Name: ICD-10 Code for Long term (current) use of anticoagulants

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: Long term (current) use of anticoagulants


Excludes2: long term (current) use of aspirin (Z79.82)


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.

I'm wondering what code I should use for the chronic anticoagulation. There is no mention of hemorrhage and the patient is on Coumadin. 790.92 shouldn't be used for patient's on Coumadin Therapy.

Any thoughts would be greatly appreciated!

790.92 is for an abnormal coagulation profile not for Coumadin therapy.
You would use v58.61 long-term (current) use of anticoagulants to code current Coumadin use. If the physician documents that the coagulation profile is abnormal then you could code it. In the ICD 9 under the code in the tabular it gives examples of what constitutes abnormal or prolonged.
