Progesterone receptor positive status

This code indicates that a patient's tumor cells have tested positive for progesterone receptors (PR). The presence of PR suggests that the cancer may be hormone-sensitive and potentially responsive to endocrine therapies. It is a crucial biomarker in the management of certain cancers, particularly breast cancer.

Use this code when laboratory or pathology reports confirm the presence of progesterone receptors in a tumor biopsy or surgical specimen. This is commonly documented for patients diagnosed with breast cancer to guide treatment decisions. It may also be relevant in other hormone-sensitive cancers where PR status is assessed.

• Always verify PR status from the pathology report; do not assume based on clinical suspicion.
• This code is typically used as a secondary diagnosis to provide additional specificity about the tumor characteristics.
• Do not code this if the report indicates "progesterone receptor negative" or "equivocal."
