Which organization publishes the Official Guidelines for Coding and Reporting for ICD-10-CM?
Answer: CMS and NCHS
The Official Guidelines for ICD-10-CM Coding and Reporting are published jointly by CMS (Centers for Medicare & Medicaid Services) and the NCHS (National Center for Health Statistics).
A patient undergoes a procedure and develops a complication requiring a return to the OR. The complication code should be sequenced:
Answer: As the principal or first-listed diagnosis
When a complication requires a return to the OR, it becomes the principal diagnosis for that subsequent encounter.
What type of code is used when a patient has a condition that is not yet confirmed but is being evaluated?
Answer: Signs and symptoms codes
In outpatient settings, coders report signs and symptoms rather than unconfirmed diagnoses; uncertain diagnoses may only be coded as confirmed in inpatient settings.
The global surgical package typically includes all of the following EXCEPT:
Answer: Treatment of unrelated conditions during the postoperative period

A patient is admitted for chemotherapy for breast cancer. What is the correct sequencing?

When a patient is admitted specifically for chemotherapy, Z51.11 (encounter for antineoplastic chemotherapy) is sequenced first, followed by the malignancy code.
Which of the following best describes the function of a 'crosswalk' in medical coding?
Answer: A tool for translating codes between different coding systems
A crosswalk maps equivalent or corresponding codes between different coding systems (e.g., ICD-9-CM to ICD-10-CM) to facilitate translation during transitions.
