1Which of the following best describes the primary scope of outpatient clinical documentation integrity (CDI)?
A.Documentation supporting accurate diagnosis capture and risk adjustment across ambulatory care settings
B.Assignment of MS-DRGs for inpatient admissions
C.Calculation of the inpatient case mix index
D.Determining the principal diagnosis after discharge
Explanation: Outpatient CDI focuses on accurate, complete, and specific provider documentation across ambulatory settings such as physician practices, hospital clinics, observation, and the ED. Its central goals include diagnosis specificity and supporting risk adjustment (HCC) capture rather than inpatient DRG assignment.
2A patient is placed in observation status in the hospital. For coding and billing purposes, observation services are generally considered:
A.Inpatient services
B.Outpatient services
C.Skilled nursing services
D.Home health services
Explanation: Observation is an outpatient status even though the patient may occupy a hospital bed. Observation services are billed under outpatient rules, and ICD-10-CM outpatient coding guidelines (Section IV) apply.
3Which setting is NOT typically within the scope of an outpatient CDI program?
A.Hospital-based physician clinic
B.Emergency department
C.Inpatient acute care medical-surgical unit
D.Ambulatory surgery center
Explanation: Outpatient CDI covers physician practices, hospital outpatient clinics, the ED, observation, ambulatory surgery, and infusion centers. The inpatient acute care medical-surgical unit falls under traditional inpatient CDI.
4An infusion center documents administration of chemotherapy. Outpatient CDI review in this setting most often focuses on ensuring documentation supports:
A.The inpatient principal procedure
B.DRG relative weight optimization
C.The 72-hour payment window
D.Medical necessity and the specific drug, dose, and diagnosis driving treatment
Explanation: In infusion and injection settings, CDI confirms documentation supports medical necessity, the specific agent administered, the start/stop times, and the linked diagnosis. This supports accurate CPT/HCPCS reporting and coverage.
5In a physician practice, which clinician documentation is typically the basis for diagnosis code assignment in the outpatient setting?
A.The treating provider's progress note and assessment/plan
B.The nursing intake vitals only
C.The lab requisition form alone
D.The patient's self-reported medical history form
Explanation: Codes are assigned from the documentation of the provider responsible for the patient's care, typically the assessment and plan of the progress note. Nursing notes, requisitions, and patient-completed forms cannot independently establish a coded diagnosis.
6Which professional is the typical end-user audience for outpatient CDI provider education on diagnosis specificity?
A.Hospital boiler-room engineers
B.Ambulatory physicians and advanced practice providers
C.Inpatient pharmacy technicians only
D.Medical records scanning staff
Explanation: Outpatient CDI specialists primarily educate the treating clinicians, physicians and APPs (NPs, PAs), whose documentation drives diagnosis capture and risk adjustment. Engagement with providers is a core competency.
7A key difference between inpatient and outpatient CDI is that outpatient CDI more heavily emphasizes:
A.Sequencing the principal diagnosis
B.Optimizing the geometric mean length of stay
C.Capturing chronic conditions affecting risk adjustment over the year
D.Querying for present-on-admission indicators
Explanation: Outpatient CDI emphasizes capturing and documenting all relevant chronic conditions (often via MEAT) each year to support accurate HCC and RAF risk adjustment. Principal diagnosis sequencing, GMLOS, and POA indicators are inpatient-specific.
8An ED encounter results in the patient being discharged home. ED professional services are reported using:
A.MS-DRGs
B.Inpatient consultation codes
C.Observation hour-based codes only
D.ED E/M codes (99281–99285) based on medical decision making
Explanation: Emergency department professional E/M services are reported with codes 99281–99285, leveled primarily on medical decision making. MS-DRGs apply only to inpatient stays.
9Why is the ambulatory surgery center (ASC) an important focus for outpatient CDI?
A.Documentation must support medical necessity and accurate procedure/diagnosis linkage for the surgery
B.ASCs assign MS-DRGs
C.ASCs require POA reporting
D.ASCs use the inpatient-only procedure list for all cases
Explanation: In an ASC, CDI verifies that documentation supports medical necessity for the procedure and links the correct diagnosis to the surgical CPT code. The inpatient-only list, by definition, excludes ASC procedures.
10A CDI specialist notices a provider consistently documents 'diabetes' without specifying type or complications. The CDI role here is primarily to:
A.Independently assign the most specific code without provider input
B.Educate and query for greater specificity to support accurate code assignment
C.Delete the diagnosis from the record
D.Bill the highest-paying diabetes code by default
Explanation: CDI improves documentation through provider education and compliant queries, prompting specificity such as diabetes type and any complications. The CDI specialist cannot assign or invent diagnoses the provider did not document.
