    Typical Clinical Scenarios

    • A 62-year-old woman presents for routine surveillance and counseling after a successfully treated stage I left breast cancer five years earlier; she reports no new symptoms but requests documentation of her cancer history for ongoing care coordination. The clinician documents the personal history of malignant neoplasm of the breast to indicate prior disease that affects surveillance and screening recommendations. Typical codes: Z85.3.
    • A 48-year-old man is evaluated in the emergency department for new onset hematuria and flank pain; he previously underwent nephrectomy for renal cell carcinoma three years ago and now requires distinction between recurrent/metastatic disease versus new urinary tract pathology. A code denoting personal history of malignant neoplasm of the kidney is recorded to flag the prior malignancy as relevant to current diagnostic workup and interpretation of imaging. Typical codes: Z85.51, Z85.52
    • A 70-year-old patient with a history of multiple resected cutaneous melanomas presents to primary care for medication reconciliation and preventive care; the clinician notes the remote melanomatous lesions to document increased long-term risk and influence screening and counseling about sun protection. The visit is billed with a personal history of malignant neoplasm of skin code to capture the past cancer as a comorbidity affecting preventive care planning. Typical codes: Z85.820, Z85.828.
