Z79.8Other long term (current) drug therapy

Z79.8 is the ICD-10-CM diagnosis code for other long term (current) drug therapy. It belongs to category Z79 (long term (current) drug therapy), block Z77-Z99 (persons with potential health hazards related to family and personal history and certain conditions influencing health status) and chapter 21 (factors influencing health status and contact with health services). It is a header code, so it can't be reported by itself; one of its 6 subcodes must be used instead.

Within Z79, choose Z79.8 (Other long term (current) drug therapy) only when documentation doesn't support a more specific option: long term (current) use of anticoagulants and antithrombotics/antiplatelets (Z79.0), long term (current) use of non-steroidal anti-inflammatories (NSAID) (Z79.1), long term (current) use of antibiotics (Z79.2), long term (current) use of hormonal contraceptives (Z79.3), long term (current) use of insulin (Z79.4), long term (current) use of steroids (Z79.5) and long term (current) use of immunomodulators and immunosuppressants (Z79.6).

To report this condition, pick the subcode that matches the documentation: Z79.81 (levels), Z79.82 (aspirin), Z79.83 (bisphosphonates), Z79.84 (drugs), Z79.85 (drugs) and Z79.89 (therapy).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
