Free Practice Questions for ACDIS CCDS-O Exam

A prospective query is initiated early enough (before or during the visit workflow) so the provider can evaluate, assess, and document the condition in real time while the patient is present. This is a major provider benefit because it supports better clinical accuracy and completeness: the clinician can ask targeted questions, perform relevant exam elements, review results, and determine whether the condition is present, active, being monitored, or ruled out—then document the final clinical impression and plan. From an ACDIS outpatient CDI perspective, prospective querying improves efficiency and reduces retrospective “chart-chasing,” late addenda, and documentation gaps that occur when clarification is requested after the encounter is closed. Importantly, prospective queries must remain non-leading and cannot direct the provider to a particular diagnosis (eliminating option A). They also cannot “guarantee” risk-adjusted capture because the diagnosis must be clinically supported and addressed (eliminating option B). Defining the purpose of the encounter is driven by the clinical reason for visit, not by CDI (eliminating option D).

A leading query is one that steers the provider toward a particular diagnosis or limits clinically appropriate choices in a way that can be perceived as prompting. Option D is leading because it presents a single, high-impact diagnosis (“alcohol dependence”) and forces a binary yes/no response without offering reasonable alternative interpretations (e.g., alcohol use, alcohol abuse/harmful use, dependence in remission, or clinically undetermined) or an “other” option. In addition, it attempts to obtain a potentially new diagnosis based on one data point (quantity consumed) without a balanced set of diagnostic possibilities and supporting clinical indicators (tolerance, withdrawal, impairment, failed attempts to cut down, etc.). By contrast, A is open-ended and requests clarification of the treated condition; B provides two plausible classification choices (active vs history); and C offers multiple reasonable BMI-related diagnostic options plus “other” and “clinically undetermined,” which supports compliant, non-leading clarification. Therefore, D best fits the definition of a leading query.

Outpatient/provider coding relies on two major code sets: ICD-10-CM for diagnoses and CPT/HCPCS for professional services, procedures, and supplies. Because of that, outpatient coding authority is anchored not only in the ICD-10-CM Official Guidelines and AHA Coding Clinic guidance for diagnosis reporting, but also in the authoritative guidance that clarifies CPT/HCPCS reporting. ACDIS outpatient CDI education stresses that CDI specialists must understand both sides: the diagnosis coding rules (ICD-10-CM) and the procedural/service reporting rules (CPT/HCPCS) that drive much of outpatient reimbursement. AMA’s CPT Assistant is a key interpretive authority for CPT coding guidance, while AHA’s Coding Clinic for HCPCS provides clarification on HCPCS Level II reporting. The other options focus on ICD-10-PCS guidelines and DRG tools, which are primarily inpatient facility concepts (PCS is inpatient procedure coding; DRGs are inpatient payment groupers). Therefore, the correct supplemental outpatient authority pair is AHA’s Coding Clinic for HCPCS and AMA’s CPT Assistant.

The documentation explicitly links the conditions by stating “Type 2 Diabetes with bilateral peripheral arteriosclerotic disease of LE,” which supports a diabetic circulatory manifestation rather than “diabetes without complications.” In outpatient CDI chart review, the word “with” and clear provider linkage allow coding of diabetes “with peripheral angiopathy” (a diabetes complication category) when peripheral arterial/arteriosclerotic disease is documented as associated. In addition, best practice is to code both the diabetes complication category and the specific manifestation when supported, because the manifestation (atherosclerosis of the lower extremities, bilateral) further describes the clinical condition being evaluated. Hypertension is also evaluated and managed (“well controlled on Lopressor”), meeting outpatient reporting expectations for an active condition addressed during the encounter. Option D is incorrect because it double-counts the same concept—peripheral angiopathy already represents a circulatory complication, so adding a separate “diabetes with circulatory complication” statement is redundant rather than additive. Therefore, the correct coding set includes diabetes with peripheral angiopathy, the bilateral lower-extremity atherosclerosis manifestation, and hypertension.

Outpatient ICD-10-CM guidance allows certain code elements to be based on documentation from clinicians other than the patient’s diagnosing provider when those elements are considered objective, routinely assessed, and commonly documented by nursing or ancillary staff. A key example ispressure ulcer staging, which is frequently assessed and documented by wound care nurses and other qualified clinicians as part of routine skin/wound evaluation. Because the stage drives code specificity and is an observable clinical finding, coders may use non-provider documentation to assign the stage when it is clearly documented and not contradicted by the provider record. In contrast, items such as thetype of obesitygenerally require provider diagnosis/clinical assessment rather than ancillary documentation alone. Similarly, while status conditions (like amputations or ostomies) may be observed, the coding guidelines do not broadly permit assigning these diagnoses solely from non-provider documentation without provider confirmation, unless the chart otherwise supports it. Therefore, among the choices, pressure ulcerstageis the appropriate circumstance where non-provider documentation can support ICD-10-CM assignment.

Stage 3 pressure ulcers are defined byfull-thickness skin losswhere the injury extends through the dermis and involvesdamage or necrosis of subcutaneous tissue. Clinically, the ulcer may present as a deep crater and can include undermining or tunneling, but the key boundary is thatbone, tendon, and muscle are not exposed. That deeper involvement (exposed muscle/tendon/bone) is characteristic of Stage 4, making option C incorrect. Option D describes partial-thickness loss, which aligns with Stage 2 (epidermis/dermis involvement such as abrasion or blister). Option A reflects early skin changes that correspond more closely to Stage 1 (intact skin with non-blanchable erythema and possible localized edema/induration). In outpatient CDI chart review, accurately distinguishing Stage 3 from Stage 2 and Stage 4 is essential because staging drives severity capture, care planning (wound care interventions, debridement considerations), and quality reporting. Documentation should clearly support “full thickness,” the tissue layers involved, and the absence of exposed bone/tendon/muscle.

In ambulatory CDI chart review, clinical indicators should align with assessment and management captured in the note (problem relevance and MEAT-style support: monitor, evaluate, assess/address, treat). This visit has two strong indicators that warrant medication evaluation. First, dyspnea plus a rapid 10-lb weight increase over two weeks is a classic signal of possible fluid overload in a patient with heart failure, making a loop diuretic such as Lasix clinically relevant to assess (effectiveness, adherence, dose changes, exacerbation risk, and whether HF is stable vs decompensated). Second, the A1c has worsened significantly (9.2 from 7.2), indicating inadequate glycemic control that should prompt review and adjustment of diabetes therapy; insulin such as NovoLog is directly tied to diabetes treatment escalation or optimization. The other medication pairs do not logically match the documented problems and indicators (e.g., appetite stimulant/anemia therapy, immunosuppressant, antidepressant/antihistamine). Therefore, NovoLog and Lasix best reflect what should be evaluated and addressed

A yes/no query format is considered compliant when it is used toresolve a clear documentation conflictand the provider is being asked to confirm which statement accurately reflects the patient’s condition for that encounter. In these situations, the intent is not to introduce a new diagnosis or steer the provider toward a particular coded outcome, but to reconcile inconsistent information already present in the record (e.g., one clinician documents a condition and another documents the opposite, or different notes describe different statuses). A focused yes/no confirmation can be appropriate because the clinical question is essentially binary: which interpretation is correct. By contrast, obtaining a new diagnosis generally requires an open-ended or multiple-choice format with balanced options (including “unable to determine”) and strong encounter-specific indicators to avoid leading. Likewise, organism specification and acuity clarification often involvemore than two clinically valid possibilities(different organisms, acute vs chronic vs acute-on-chronic, etc.), making yes/no overly restrictive and potentially leading. Therefore, resolving conflicting documentation is the best fit for a compliant yes/no query.

In CMS-HCC risk adjustment, RAF impact comes from reporting qualifying chronic diseases (HCCs), not from nonspecific symptom-only documentation. “Angina pectoris, unspecified” is frequently a symptom-level statement and, by itself, often does not carry the same risk-adjustment weight as documenting and coding the underlying ischemic heart disease responsible for the angina (for example, coronary artery disease/atherosclerotic heart disease with angina). Ambulatory CDI practice emphasizes that when providers document only “angina,” coders may be limited to a symptom code, which can under-represent the patient’s true disease burden in the HCC model. This makes angina an excellent target for provider education: clarify whether the angina is due to CAD, whether CAD is present and being managed, and whether there are related manifestations (e.g., unstable angina, prior MI history, status post CABG/stent) that support more complete, clinically accurate reporting. By improving documentation linkage from symptom (angina) to the definitive chronic condition (CAD with angina), the provider can more reliably capture an HCC-relevant diagnosis and positively influence RAF accuracy.

CDI staff do not alter the legal health record and should not “code it as is” when documentation is unclear, conflicting, or incomplete in a way that impacts accurate reporting. The compliant next step is to issue a provider query for clarification, ensuring the final record accurately reflects the provider’s clinical judgment. ACDIS-guided outpatient CDI emphasizes that queries are a quality and compliance tool: they reconcile discrepancies (e.g., conflicting diagnoses across notes, missing linkage between symptoms and conditions, unclear acuity such as “CHF” without type/status, or ambiguous infection documentation). The query should be supported by clinical indicators from the chart and should ask the provider to document the clarified diagnosis/status in the record (progress note, addendum, or appropriate attestation). Escalation to compliance is reserved for patterns of nonresponse, suspected integrity concerns, or systemic issues, not routine discrepancies. The objective is to achieve a complete, consistent clinical story that supports coding, risk adjustment, quality reporting, and medical necessity—through provider clarification, not CDI edits.
