Explanation

Anemia associated with malignancy
When admission/encounter is for management of an anemia associated with the malignancy, and the treatment is only for anemia, the appropriate code for the malignancy is sequenced as the principal or first-listed diagnosis followed by the appropriate code for the anemia (such as code D63.0, Anemia in neoplastic disease).

Correct Answer

A. D61.2, C71.9, Y84.2, 30233N1

Explanation

Anemia associated with chemotherapy, immunotherapy and radiation therapy
When the admission/encounter is for management of an anemia associated with an adverse effect of the administration of chemotherapy or immunotherapy and the only treatment is for the anemia, the anemia code is sequenced first followed by the appropriate codes for the neoplasm and the adverse effect (T45.1X5, Adverse effect of antineoplastic and immunosuppressive drugs).
When the admission/encounter is for management of an anemia associated with an adverse effect of radiotherapy, the anemia code should be sequenced first, followed by the appropriate neoplasm code and code Y84.2, Radiological procedure and radiotherapy as the cause of abnormal reaction of the patient, or of later complication, without mention of misadventure at the time of the procedure

The patient had a melanoma removed from his back 4 years ago. The patient is currently being treated for metastatic melanoma of the right lung:

C43.59, C78.01
Z85.828, C78.01
C43.58, C78.02
C78.01, Z85.820

Correct Answer

A. C78.01, Z85.820

Explanation

Primary malignancy previously excised
When a primary malignancy has been previously excised or eradicated from its site and there is no further treatment directed to that site and there is no evidence of any existing primary malignancy, a code from category Z85, Personal history of primary and secondary malignant neoplasm, should be used to indicate the former site of the malignancy. Any mention of extension, invasion, or metastasis to another site is coded as a secondary malignant neoplasm to that site. The secondary site may be the principal or first-listed with the Z85 code used as a secondary code.

The patient was admitted for chemotherapy (percutaneous central vein) treatment of acute lymphocytic leukemia (ALL):

Z51.11, C91.00, 3E04305
C91.01, Z51.12, 3E04305
Z51.10, C91.00, 3E04305
C91.02, Z51.11, 3E04305

Correct Answer

A. Z51.11, C91.00, 3E04305

Explanation

Patient admission/encounter solely for administration of chemotherapy, immunotherapy and radiation therapy
If a patient admission/encounter is solely for the administration of chemotherapy, immunotherapy or radiation therapy assign code Z51.0, Encounter for antineoplastic radiation therapy, or Z51.11, Encounter for antineoplastic chemotherapy, or Z51.12, Encounter for antineoplastic immunotherapy as the first-listed or principal diagnosis. If a patient receives more than one of these therapies during the same admission more than one of these codes may be assigned, in any sequence.
The malignancy for which the therapy is being administered should be assigned as a secondary diagnosis.

Z51.0, C85.90, E86.0, T45.1x5A, R11.2, 3E05305

Correct Answer

A. Z51.11, C85.90, E86.0, T45.1x5A, R11.2, 3E05305

Explanation

Patient admitted for radiation therapy, chemotherapy or immunotherapy and develops complications
When a patient is admitted for the purpose of radiotherapy, immunotherapy or chemotherapy and develops complications such as uncontrolled nausea and vomiting or dehydration, the principal or first-listed diagnosis is Z51.0, Encounter for antineoplastic radiation therapy, or Z51.11, Encounter for antineoplastic chemotherapy, or Z51.12, Encounter for antineoplastic immunotherapy followed by any codes for the complications.

Explanation

Malignant neoplasm in a pregnant patient
When a pregnant woman has a malignant neoplasm, a code from subcategory 09A.1-, Malignant neoplasm complicating pregnancy, childbirth, and the puerperium, should be sequenced first, followed by the appropriate code from Chapter 2 to indicate the type of neoplasm.

Correct Answer

A. T81.4xxA, L03.311, C18.9, Y83.2

Explanation

Complication from surgical procedure for treatment of a neoplasm
When an encounter is for treatment of a complication resulting from a surgical procedure performed for the treatment of the neoplasm, designate the complication as the principal/first-listed diagnosis. See guideline regarding the coding of a current malignancy versus personal history to determine if the code for the neoplasm should also be assigned
