CCDS Exam Dumps - ACDIS Clinical Documentation Specialist Questions and Answers

When severe sepsis is documented, coding requires the underlying systemic infection first, followed by the appropriate severe-sepsis code and additional code(s) for the acute organ dysfunction. Therefore, the sepsis code is sequenced first, followed by the severe-sepsis code and acute kidney injury.

The FY 2026 ICD-10-CM Official Guidelines state that severe sepsis requires at least two codes: one for the underlying systemic infection and another from subcategory R65.2-. Additional codes identify associated acute organ dysfunction. A code from R65.2- cannot serve as the principal diagnosis.

The UTI identifies the localized source but does not replace the systemic infection as principal diagnosis when sepsis is the condition chiefly responsible for admission. Likewise, the AKI is a manifestation of the severe systemic process and is not sequenced before the sepsis in this scenario.

For CDI specialists, the essential documentation element is the relationship between sepsis and the acute organ dysfunction. Organ dysfunction alone does not automatically permit severe-sepsis coding; provider documentation must establish the association when it is not inherent.

CCDS Reference Topics: Sepsis; severe sepsis; organ dysfunction; sequencing; principal diagnosis.

Medicare's Indirect Medical Education (IME) adjustment uses the hospital's resident-to-bed ratio as the principal measure of teaching intensity. CMS explains that the IME adjustment factor is calculated using a hospital's ratio of residents to beds. Therefore, the correct answer is inpatient beds.

IME is an additional IPPS payment intended to recognize the higher indirect patient-care costs associated with operating an approved teaching program. These costs are distinguished from Direct Graduate Medical Education payments, which reimburse qualifying direct costs associated with residency training.

The number of admissions is not the denominator in the IME teaching-intensity calculation. Likewise, emergency-department beds are not simply combined with inpatient beds for the standard resident-to-bed ratio, and disproportionate-share payment rates represent a separate IPPS adjustment related principally to hospitals caring for substantial numbers of low-income patients.

For the CCDS examination, the important distinction is that IPPS reimbursement involves more than the base MS-DRG payment. Adjustments may include IME, disproportionate-share hospital provisions, wage-index effects, outlier payments, and other statutory mechanisms.

CCDS Reference Topics: IPPS reimbursement; teaching hospitals; IME adjustment; resident-to-bed ratio.

A compliant clinical-validation process should include a defined escalation process. The AHIMA/ACDIS query guidance specifically recommends organizational query policies that address escalation when a query remains unanswered or when documentation and clinical-validation concerns cannot be resolved through the ordinary workflow. Escalation may involve CDI or coding leadership, a physician advisor, the chief medical officer, or other designated personnel according to organizational policy.

Option A is inappropriate because simply coding every documented diagnosis without addressing significant clinical-support concerns undermines data integrity and increases denial and compliance risk. Option B is also too absolute. Coding professionals cannot independently substitute their clinical judgment for that of the responsible provider; unclear or potentially unsupported diagnoses should be addressed through an established clarification and validation process. Option D is incorrect because queries may appropriately occur concurrently or retrospectively depending on the circumstances and organizational workflow.

The goal of clinical validation is not to force removal or confirmation of a diagnosis. It is to ensure that the provider has an opportunity to clarify whether the diagnosis accurately represents the patient's clinical condition and to document supporting reasoning where appropriate.

CCDS Reference Topics: Professionalism, ethics, and compliance; clinical validation; compliant query policies; escalation procedures.

CMS specifically includes deep vein thrombosis and pulmonary embolism following certain orthopedic procedures, including total knee replacement and hip replacement, among Hospital-Acquired Conditions subject to the HAC/POA payment provisions. Therefore, option C is correct.

Under the IPPS HAC payment policy, qualifying conditions that were not present on admission may lose their normal CC/MCC effect for MS-DRG assignment when all applicable criteria are met. This makes accurate POA determination essential in CDI and coding.

Pressure ulcers are also part of the HAC framework, but the CMS category historically applies specifically to Stage III and Stage IV pressure ulcers. An unstageable pressure ulcer does not automatically satisfy the Stage III/IV HAC category merely because it is severe or clinically significant. CMS materials distinguish an unstageable ulcer from a documented Stage III or IV ulcer.

Postoperative pneumonia and septic shock are not, by themselves, the specified HAC category represented by the answer choices.

The CCDS blueprint specifically requires candidates to identify CMS-designated HACs and understand the effect of POA assignment on payment.

CCDS Reference Topics: IPPS; Hospital-Acquired Conditions; POA; MS-DRG adjustment.

The record contains uncertainty regarding whether the documented ileus represents expected postoperative physiology or a clinically significant complication, making provider clarification appropriate.

Temporary impairment of gastrointestinal motility is common following abdominal surgery. Therefore, the mere occurrence of an ileus after surgery does not automatically establish a complication of care. Conversely, prolonged or clinically significant postoperative ileus requiring substantial treatment, extended hospitalization, nasogastric decompression, or other interventions may warrant distinct documentation.

The CDI specialist must not infer the complication relationship solely from timing. The Official Guidelines emphasize that a condition occurring after medical or surgical care is not automatically classified as a complication; appropriate provider documentation of the relationship and clinical significance is required where applicable.

Option C is also incorrect because postoperative ileus can be a reportable condition when clinically significant and appropriately documented. Option D substitutes a separate diagnosis without provider support.

The query should provide relevant duration, symptoms, imaging, diet status, nasogastric tube use, treatment, and expected postoperative course while allowing the surgeon to characterize the condition.

CCDS Reference Topics: Postoperative ileus; complications of care; postoperative documentation; clinical clarification.

Accurate discharge disposition is critical to application of the Post-Acute Care Transfer policy because the patient's destination after the acute inpatient stay can determine whether transfer-payment methodology applies.

Qualifying discharges to certain post-acute settings can be subject to transfer-payment rules when other criteria are met. These settings can include skilled nursing facilities and other specified post-acute arrangements, depending on applicable CMS requirements and the MS-DRG involved.

Therefore, an incorrectly documented discharge destination can affect reimbursement even when the diagnoses, procedures, and MS-DRG are otherwise accurate.

The PACT concept demonstrates why CDI and coding accuracy extend beyond diagnosis capture. The inpatient claim also relies on accurate demographic, procedural, discharge-status, and utilization information.

Dietary preference, physician experience, and the number of daily progress notes do not determine whether PACT methodology applies.

CDI specialists should recognize when conflicting documentation exists regarding whether a patient went home, to skilled nursing, rehabilitation, another acute facility, hospice, or another destination and collaborate with the appropriate departments to ensure the final record accurately reflects the actual disposition.

CCDS Reference Topics: PACT; discharge disposition; IPPS transfer rules; reimbursement; data integrity.

The most effective intervention is targeted, service-line-specific physician education based on actual documentation trends and clinically relevant examples.

Repeated queries for the same issue usually indicate a systematic documentation opportunity rather than isolated provider mistakes. Education should therefore show cardiologists how documentation of heart-failure type—such as systolic, diastolic, or combined—and acuity—acute, chronic, or acute on chronic—communicates the patient's clinical condition more precisely.

Using deidentified examples from the service line makes the education immediately relevant and enables physicians to recognize which clinical circumstances frequently generate clarification. Aggregate query data can demonstrate where documentation gaps occur without criticizing individual providers.

Sending an entire code book places coding responsibility on physicians and is unlikely to change documentation behavior. Stopping queries leaves unresolved clinical ambiguity. Framing the education around reduced reimbursement is also inappropriate because the goal of CDI education is accurate clinical representation, not coaching physicians toward higher-paying diagnoses.

The 2026 ACDIS/AHIMA query guidance identifies accurate representation of the patient's clinical status as the underlying purpose of CDI clarification.

CCDS Reference Topics: Physician education; communication; heart-failure specificity; query trend analysis.

The clinical pattern supports consideration of acute tubular necrosis (ATN) as a clarification opportunity. Prolonged hypotension can cause renal ischemia severe enough to injure tubular epithelial cells. A substantial acute creatinine increase and granular or “muddy brown” casts are classic clinical findings associated with ATN.

The provider has already documented acute renal failure, so the purpose of the query would be to clarify the underlying type of acute kidney injury when clinically appropriate—not to create AKI from laboratory data alone.

Stage 5 chronic kidney disease requires evidence of chronic, persistent severe renal dysfunction and cannot be inferred from an acute creatinine rise following hypotension. Nephrotic syndrome is characterized principally by substantial proteinuria, hypoalbuminemia, edema, and other findings not described here. Pyelonephritis would ordinarily require evidence of upper urinary infection.

A CDI specialist should review the complete clinical record, including baseline renal function, hemodynamic course, nephrology notes, urinalysis, fluid management, nephrotoxic exposures, and renal replacement therapy when applicable.

The CCDS competency framework includes renal failure, laboratory interpretation, and recognition of clinically supported opportunities for diagnostic specificity.

CCDS Reference Topics: Acute kidney injury; acute tubular necrosis; renal pathophysiology; clinical indicators; diagnostic specificity.

The arterial blood gas primarily demonstrates respiratory acidosis. The pH is significantly acidemic at 7.24, while PaCO₂ is markedly elevated at 72 mmHg. Because carbon dioxide acts as an acid through the carbonic acid buffering system, CO₂ retention lowers blood pH.

The bicarbonate of 30 mEq/L is mildly elevated, suggesting some renal compensation, which may occur in patients with chronic CO₂ retention from COPD. However, the substantial acidemia indicates that compensation is insufficient and an acute component may be present.

In a COPD patient with acute respiratory distress, such findings can create an appropriate clinical basis for clarification of acute or acute-on-chronic hypercapnic respiratory failure when other supporting indicators are present, such as worsening work of breathing, altered mental status, escalating oxygen needs, BiPAP, or intubation.

The CDI specialist should not independently equate every abnormal ABG with respiratory failure. The provider determines the clinical diagnosis.

Respiratory alkalosis would involve reduced PaCO₂. Metabolic acidosis generally involves reduced bicarbonate as the primary disturbance, while metabolic alkalosis involves primary bicarbonate elevation with alkalemia.

CCDS Reference Topics: ABG interpretation; respiratory acidosis; hypercapnia; COPD; respiratory failure.

The phrase “post-op ileus” establishes that the ileus occurred after surgery, but it does not necessarily establish that the ileus represents a reportable surgical complication rather than an expected transient consequence of abdominal surgery. The relationship and clinical significance therefore require clarification.

ICD-10-CM guidance on complications of care states that not every condition occurring during or following surgery is automatically classified as a complication. Code assignment depends on provider documentation establishing the relationship between the condition and the care or procedure, and the documentation must support clinical significance. When that relationship is unclear, the provider should be queried.

Assigning a complication code immediately would therefore be premature. Likewise, simply coding postoperative ileus without resolving whether it represents expected postoperative physiology or a clinically significant complication could misrepresent the episode.

Escalation to a physician advisor or CDI manager is unnecessary as the first action because this is a standard documentation-clarification issue that can be addressed directly through a compliant provider query.

CCDS Reference Topics: Official Guidelines—complications of care; medical record documentation; compliant provider clarification.
