question 7
a woman has identified a lump in her right breast. after examination, the physician decides a biopsy is indicated. a specimen is sent for pathologic examination. the finding is carcinoma of the breast in the upper inner quadrant. what diagnosis is assigned for the pathologic examination?

z01.419
n63.12
c50.211
c80.1

Explanation:

Identify the definitive diagnosis from the pathology report

The pathology examination confirms a definitive finding of "carcinoma of the breast in the upper inner quadrant" of the right breast. Under ICD-10-CM coding guidelines, when a definitive diagnosis is established by a pathologic examination, that definitive diagnosis (malignant neoplasm of the breast) must be coded rather than the presenting symptom (breast lump).

Determine the correct ICD-10-CM code

• C50 represents Malignant neoplasm of breast.
• C50.2 represents Malignant neoplasm of upper-inner quadrant of breast.
• C50.21 represents Malignant neoplasm of upper-inner quadrant of female breast.
• C50.211 represents Malignant neoplasm of upper-inner quadrant of right female breast.

Rule out incorrect options

• Z01.419 is for routine gynecological examination, which is incorrect.
• N63.12 is for an unspecified lump in the left breast, which is incorrect because a definitive malignant diagnosis has been established for the right breast.
• C80.1 is for malignant neoplasm, unspecified, which is incorrect because the specific site (upper-inner quadrant of the right female breast) is documented.

Answer:

• (A) Z01.419
• (B) N63.12
• (C) C50.211 (Correct answer)
• (D) C80.1
