Long term (current) use of myelosuppressive agent

This code indicates a patient's ongoing, prescribed use of a medication designed to suppress bone marrow activity, often to reduce the production of blood cells. This long-term therapy is typically employed to manage various medical conditions, including autoimmune disorders, certain cancers, or to prevent organ transplant rejection.

Apply this code when a patient is actively taking a myelosuppressive agent as part of a chronic treatment regimen. This includes patients on maintenance therapy for conditions like rheumatoid arthritis, lupus, or after a solid organ transplant. It should also be used for patients receiving ongoing low-dose chemotherapy that has a myelosuppressive effect.

• Always sequence this code as a secondary diagnosis, following the code for the underlying condition necessitating the myelosuppressive therapy.
• Do not use this code for acute, short-term use of myelosuppressive agents, such as during initial induction chemotherapy.
• Ensure documentation clearly states the patient is on current and long-term use of the medication.
