Long term (current) use of calcineurin inhibitor

This code indicates a patient's ongoing, long-term use of a calcineurin inhibitor medication. These immunosuppressive drugs are primarily used to prevent organ rejection in transplant recipients or to manage certain autoimmune conditions. The "current" aspect signifies that the patient is actively taking the medication at the time of the encounter.

Apply this code when documenting a patient's maintenance therapy with a calcineurin inhibitor following an organ transplant (e.g., kidney, liver, heart). It is also appropriate for patients receiving long-term calcineurin inhibitor treatment for autoimmune diseases such as severe psoriasis, rheumatoid arthritis, or inflammatory bowel disease. This code should be used in conjunction with the primary diagnosis for which the medication is prescribed.

• Always sequence this code as a secondary diagnosis, following the code for the condition being treated (e.g., organ transplant status, specific autoimmune disease).
• Do not use this code for acute or short-term use of calcineurin inhibitors; it specifically denotes long-term, current therapy.
• Ensure documentation clearly states the patient is on a calcineurin inhibitor and that its use is ongoing.
