Lng trm (crnt) use of agnt aff estrog recpt & estrog levels

This code indicates a patient's ongoing, long-term use of medications that modify estrogen receptor activity or directly impact estrogen levels, excluding hormonal contraceptives and menopausal hormone therapy. These agents are typically prescribed for conditions like breast cancer, endometriosis, or infertility.

Apply this code when documenting a patient's current, continuous use of drugs such as aromatase inhibitors (e.g., anastrozole, letrozole), selective estrogen receptor modulators (SERMs) like tamoxifen or raloxifene, or other non-contraceptive/non-menopausal hormonal agents affecting estrogen. This is often used in oncology follow-up or chronic disease management.

• Always assign this code as a secondary diagnosis to indicate the patient's current medication status.
• Ensure the medical record clearly documents the specific agent being used and the intent of long-term therapy.
• Do not use this code for short-term or acute medication use; it specifically denotes long-term, ongoing therapy.
