What are the principal and secondary ICD-10-CM diagnosis codes assigned for a female patient diagnosed with malignant ovarian carcinoma secondary to a history of cervical cancer?

• A. C79.62, Z85.41
• B. C79.61, Z85.40
• C. C79.63, Z85.42
• D. C79.64, Z85.43

Answer: (A)

In this scenario, the principal and secondary ICD-10-CM diagnosis codes are accurately represented by the choice that denotes the primary condition and its secondary ramifications based on the patient's medical history.

The principal diagnosis code, which represents the condition primarily responsible for the patient's admission or treatment, is C79.62. This specific code is used for malignancies that have metastasized to the ovaries. Since the patient has been diagnosed with malignant ovarian carcinoma, this is the appropriate principal diagnosis code.

The secondary diagnosis code, Z85.41, indicates a personal history of malignant neoplasm of the cervix. This is relevant here because the patient's history of cervical cancer is a significant factor contributing to their current diagnosis of ovarian carcinoma, as certain cancers can predispose individuals to the development of secondary malignancies.

Thus, the chosen answer encompasses both the current cancer diagnosis and the relevant past medical history, capturing the full context of the patient’s situation in line with the ICD-10-CM coding guidelines. The combination of C79.62 and Z85.41 effectively communicates the principal diagnosis of malignant ovarian carcinoma in conjunction with a pertinent history, which is essential for proper coding and care planning.
