Z79.6Long term (current) use of immunomodulators and immunosuppressants

Z79.6 is the ICD-10-CM diagnosis code for long term (current) use of immunomodulators and immunosuppressants. 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 (long term (current) drug therapy), Z79.6 is specifically for long term (current) use of immunomodulators and immunosuppressants. Related codes cover 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 other long term (current) drug therapy (Z79.8).

To report this condition, pick the subcode that matches the documentation: Z79.60 (immunosuppressants), Z79.61 (immunomodulator), Z79.62 (immunosuppressant), Z79.63 (agent), Z79.64 (agent) and Z79.69 (immunosuppressants).

The conditions in its Excludes2 note aren't part of Z79.6, but may be coded alongside it if the patient has both: long term (current) use of steroids (Z79.5-) and long term (current) use of agents affecting estrogen receptors and estrogen levels (Z79.81-).
