ACDIS Updated CCDS Exam Questions and Answers by asees

For FY 2026, CMS Hospital Value-Based Purchasing performance is organized into four domains: Clinical Outcomes; Person and Community Engagement; Safety; and Efficiency and Cost Reduction. CMS reports that each domain contributes to the hospital's Total Performance Score, with the FY 2026 dataset showing weighted scores for all four domains.

The Hospital VBP Program is funded by reducing participating hospitals' base operating DRG payments by 2% and redistributing the amount through value-based incentive payments according to program performance.

CDI professionals are particularly relevant to quality reporting because complete and accurate documentation can influence coded clinical information used in mortality, complications, risk adjustment, patient-safety analysis, and other quality processes. Documentation integrity should not be manipulated to improve scores; rather, the health record must accurately reflect the patient's actual severity and clinical course.

ACDIS explicitly includes Hospital VBP measures, SOI/ROM, Patient Safety Indicators, and publicly reported quality data within CCDS program-analysis competencies.

CCDS Reference Topics: Hospital VBP; quality reporting; Safety domain; Clinical Outcomes; CDI impact on publicly reported data.

Within the answer choices provided by the source question, hepatic failure is the intended clarification because the combination of cirrhosis, confusion, and markedly elevated ammonia suggests clinically significant hepatic dysfunction with an encephalopathic process.

The pathophysiologic concern is impaired hepatic detoxification and/or portosystemic shunting, allowing neurotoxins such as ammonia to accumulate and contribute to altered mental status. Other supportive findings can include asterixis, disorientation, somnolence, abnormal liver synthetic function, jaundice, ascites, and response to lactulose or rifaximin.

A crucial contemporary CDI distinction is that hepatic encephalopathy now has a dedicated ICD-10-CM code, K76.82. Therefore, current documentation practice should seek the diagnosis that most accurately represents the provider's clinical judgment—such as hepatic encephalopathy—rather than automatically equating elevated ammonia with hepatic failure. Hyperammonemia by itself is not diagnostic, and confusion can have multiple etiologies.

Alcohol dependence is addressed separately based on behavioral criteria, while alcohol poisoning requires evidence that the acute alcohol exposure is the cause of toxicity.

CCDS Reference Topics: Cirrhosis; hepatic dysfunction; hepatic encephalopathy; hyperammonemia; clinical validation and specificity.

The CDI specialist should respect the provider's independent clinical judgment, provided the response clearly addresses the query and the resulting documentation is clinically coherent.

A query is a request for clarification—not a mechanism for compelling the provider to select CDI's preferred diagnosis. Physician disagreement is therefore not inherently a failed query. The provider may appropriately document another condition, rule out a suspected condition, or explain why the indicators have another clinical interpretation.

Repeatedly querying until a desired diagnosis appears creates serious compliance risk and can undermine the integrity of the documentation process. Escalation may be appropriate in defined circumstances—for example, unresolved contradictions, unanswered high-priority queries, or persistent clinical-validation issues—but should follow organizational policy and should not occur merely because CDI dislikes the provider's answer.

The 2026 ACDIS/AHIMA guidance is the current foundational query-practice standard and emphasizes compliant clarification across healthcare settings.

Effective CDI communication requires clinical knowledge, professional dialogue, and recognition that final diagnostic determinations belong to the responsible provider.

CCDS Reference Topics: Physician communication; query responses; provider independence; escalation; professional conduct.

When two diagnoses equally meet the definition of principal diagnosis, either condition may be sequenced first when the circumstances of admission, diagnostic workup, and treatment equally support both and no specific coding guideline, tabular instruction, or other sequencing rule directs otherwise.

The principal diagnosis cannot be selected based on which option generates higher payment. Financial outcome is not a legitimate sequencing criterion.

Likewise, chronological age of the diagnosis does not determine principal-diagnosis status. The principal diagnosis is established after study as the condition chiefly responsible for occasioning the admission.

A CDI query may be appropriate when the documentation does not actually establish whether both diagnoses equally occasioned the admission. However, querying simply because one sequencing choice would produce a more favorable MS-DRG is inappropriate.

This scenario tests the distinction between valid coding flexibility and improper reimbursement-driven documentation practices. CDI professionals must understand coding conventions well enough to avoid unnecessary queries while recognizing genuine ambiguity that requires provider clarification.

The FY 2026 MS-DRG grouper and Definitions Manual published by CMS provide the applicable grouper logic for the current fiscal year.

CCDS Reference Topics: Principal diagnosis; equally qualifying diagnoses; sequencing; ethical reimbursement practice.
