Accepted Answer

C00–C96 – Malignant neoplasms

ICD-10-CM codes C00–C96 represent primary malignant neoplasms and are the primary codes targeted in diagnosis-index casefinding.

Question 2

When casefinding from the radiation oncology department, which document is the BEST primary source to identify new cancer cases?

Accepted Answer

Simulation and treatment planning records

Answer

Simulation and treatment planning records document the specific site being treated and the cancer diagnosis, making them the most useful primary casefinding source in radiation oncology.

Question 3

A registrar is conducting casefinding and finds a patient who had a positive fine needle aspiration (FNA) biopsy for malignancy performed at the facility but received all treatment elsewhere. Is this case reportable?

Accepted Answer

Yes, as an analytic case because diagnosis was made at the facility

Answer

A case is analytic when the diagnosing facility is your own, even if treatment occurs elsewhere; diagnosis at the facility makes it a Class 1 analytic case.

Question 4

What is the purpose of casefinding audits in a cancer registry program?

Accepted Answer

To verify completeness and identify missed reportable cases

Answer

Casefinding audits assess whether all reportable cases are being captured and identify gaps in the casefinding process.

Question 5

Squamous cell carcinoma of the skin is diagnosed and treated at your facility. How is this handled for registry purposes?

Accepted Answer

Not reportable under ACOS CoC standards

Answer

Squamous cell carcinoma of the skin (except lip) is excluded from reportability under ACOS CoC standards, similar to basal cell carcinoma.
