1. What is the ICD-10-CM sequencing when a patient is admitted for radiation therapy for a hemic malignancy?

   Encounter for radiotherapy (Z51.0) first, then malignancy. ICD-10-CM guidelines prioritize Z51.0 as principal when the admission is specifically for radiation therapy, followed by the malignancy code.

2. Which option is correct: "Leukemia, in relapse" versus "history of leukemia" for active treatment?

   Use the active leukemia code (relapse), not a history code (Z85.6-). Relapse indicates active disease requiring treatment, so ICD-10-CM uses the active leukemia code rather than history.

3. What is the ICD-10-CM sequencing when admission is for management of anemia due to chemotherapy?

   Anemia due to antineoplastic therapy (D64.81) first, then neoplasm and T code. When admission is for anemia management due to therapy, ICD-10-CM sequences D64.81 as principal, followed by neoplasm and adverse effect codes.

4. Which ICD-10-CM code category is used for malignant neoplasm of lymph nodes (lymphoma sites)?

   C81–C86 and C88–C96 (lymphoid/hematopoietic malignancies). ICD-10-CM categories C81-C96 classify malignant neoplasms of lymphoid and hematopoietic tissues, including various lymphoma types.

5. Identify the correct sequencing: Admission for transfusion due to anemia from chemotherapy for lymphoma.

   Anemia due to antineoplastic therapy (D64.81) first, then lymphoma and T45.1X5-. When admission is for anemia from therapy, ICD-10-CM sequences D64.81 as principal, followed by malignancy and adverse effect codes.

6. Which ICD-10-CM guideline applies to coding sickle-cell disease with crisis?

   Use the sickle-cell code with crisis and add the specific crisis type if instructed. ICD-10-CM guidelines for sickle-cell disorders require using codes that include crisis status and adding details for specific manifestations.

7. What is the ICD-10-CM rule for coding enlarged lymph nodes without a definitive diagnosis?

   Code lymphadenopathy (R59.-) when no etiology is established. ICD-10-CM guidelines direct coding signs or symptoms like lymphadenopathy when no specific diagnosis is provided.

8. Identify the correct sequencing: Admission for transfusion due to anemia from colon cancer.

   Colon cancer first, then anemia in neoplastic disease (D63.0). ICD-10-CM guidelines sequence the neoplasm as principal when admission is for anemia management associated with the malignancy.

9. What is the ICD-10-CM rule for coding thalassemia (major, intermedia, minor) when specified?

   Assign the specific thalassemia code (D56.-) matching the documented type. ICD-10-CM subcategory D56.- provides specific codes for different types of thalassemia to accurately reflect the diagnosis.

10. What is the ICD-10-CM guideline for coding anemia due to chronic kidney disease (CKD)?

    Code CKD first, then anemia in CKD (D63.1). ICD-10-CM guidelines sequence the underlying CKD as principal, followed by D63.1 for associated anemia.

11. What is the ICD-10-CM sequencing when a patient is admitted for chemotherapy for lymphoma or leukemia?

    Encounter for antineoplastic chemotherapy (Z51.11) first, then malignancy. ICD-10-CM guidelines prioritize Z51.11 as principal when the admission is specifically for administering chemotherapy, followed by the malignancy code.

12. Which ICD-10-CM guideline applies when anemia is due to a malignancy itself (not therapy)?

    Code the malignancy first, then anemia in neoplastic disease (D63.0). ICD-10-CM guidelines sequence the malignancy as principal followed by D63.0 for anemia directly caused by the neoplasm.

13. Identify the correct sequencing: Neutropenic fever due to chemotherapy (no documented sepsis).

    Fever first only if reason for visit; add D70.1 and T45.1X5- per documentation. ICD-10-CM sequences the symptom (fever) as principal if it is the admission reason, with additional codes for neutropenia and cause.

14. What is the ICD-10-CM coding rule when leukemia is documented as "in remission"?

    Assign the appropriate leukemia in remission code (C91.-–C95.- with remission). ICD-10-CM provides specific remission codes for leukemia to indicate the disease status when documented as in remission.

15. Which ICD-10-CM guideline applies when sepsis occurs in a patient with neutropenia from chemotherapy?

    Code sepsis first; add neutropenia and adverse effect codes as applicable. ICD-10-CM guidelines sequence sepsis as principal when it is the reason for admission, with additional codes for related conditions like neutropenia.

16. What is the ICD-10-CM rule for coding "history of leukemia" with no current disease?

    Use personal history of leukemia code (Z85.6-), not an active C code. When there is no evidence of current leukemia, ICD-10-CM guidelines require using the history code to reflect the absence of active disease.

17. What is the correct ICD-10-CM code selection for iron deficiency anemia due to chronic blood loss?

    Use D50.0 (iron deficiency anemia secondary to blood loss). D50.0 specifically classifies iron deficiency anemia resulting from ongoing blood loss per ICD-10-CM guidelines.

18. Which ICD-10-CM guideline applies when anemia is due to acute blood loss from trauma or surgery?

    Code the acute blood loss anemia (D62) and the underlying cause as applicable. ICD-10-CM guidelines require coding D62 for posthemorrhagic anemia along with the cause to capture the etiology.

19. Find the correct code type: Patient has Hodgkin lymphoma, currently on chemotherapy, no complications.

    Z51.11 first, then Hodgkin lymphoma code (C81.-). ICD-10-CM guidelines prioritize Z51.11 for chemotherapy encounters, followed by the active malignancy code.

20. What ICD-10-CM guideline determines the principal diagnosis for a lymphatic or hemic malignancy admission?

    Code the malignancy chiefly responsible for the admission as principal. ICD-10-CM guidelines specify that the principal diagnosis is the malignancy primarily responsible for the admission to ensure accurate reflection of the admission reason.

21. What is the ICD-10-CM rule when documentation states "metastatic lymphoma" to a node group?

    Do not use secondary malignancy codes; lymphoma codes already reflect spread. ICD-10-CM guidelines state that lymphoma codes inherently include dissemination, so secondary codes are not added for spread to lymph nodes.
