The Query Quest
This type of query is strictly prohibited by ACDIS and AHIMA guidelines because it directs a provider to a specific diagnosis or choice, or links a cause and effect without giving other clinical options.
What is a leading query?
This abbreviation refers to the primary classification system used by Medicare to determine hospital payment weights based on severity.
What is MS-DRG (Medicare Severity Diagnosis-Related Group)?
If a physician documents "uroposepsis," the coding guidelines state this cannot be coded as sepsis; instead, it defaults to this basic condition.
What is a Urinary Tract Infection (UTI)?
These non-medical factors—such as housing instability, food insecurity, and lack of transportation—are coded using the Z55-Z65 code range.
What are Social Determinants of Health (SDOH)?
Published quarterly by this specific national organization, these official guidelines provide the final, legally binding word on complex coding and documentation disputes.
What is the AHA (American Hospital Association)?
This is the critical piece of evidence—such as a lab value, vital sign, or radiology finding—that a CDI specialist must include to justify a query.
What is a clinical indicator?
These three letters represent conditions that are present at the time the patient is officially admitted to the inpatient facility.
What is POA (Present on Admission)?
To code this severe respiratory condition as a secondary diagnosis, clinical documentation must clearly differentiate it from a patient's baseline chronic state, often requiring evidence of increased oxygen demands, escalations in therapy, or non-invasive ventilation.
What is Acute Respiratory Failure (or Acute on Chronic Respiratory Failure)? What is Acute Respiratory Failure?
Unlike most diagnoses, SDOH codes can be captured and coded based on documentation from these non-physician care team members.
Who are Social Workers (or Case Managers/Nurses)?
According to a famous Coding Clinic ruling, a CDI specialist or coder cannot use a laboratory or radiology report to pull a definitive diagnosis into a claim; the diagnosis must be explicitly documented by this specific individual.
Who is the provider (or attending physician/clinician)?
ACDIS and AHIMA release this shared, authoritative document that outlines the golden rules for compliant query practices.
What is the Guidelines for Achieving a Compliant Query Practice brief?
Capturing a secondary diagnosis with this designation drastically bumps a chart's severity tier from "without" directly to the highest tier
What is an MCC (Major Complication or Comorbidity)?
This type of myocardial infarction is coded when myocardial injury is related to an ischemic imbalance (such as severe anemia, shock, or tachycardia) rather than a primary coronary arterial thrombotic event.
What is a Type 2 Myocardial Infarction (or Type 2 MI)?
This specific Z-code category reflects a patient's inability to follow a prescribed medical treatment plan, often requiring a CDI query to determine if the cause is financial or cognitive.
What is Noncompliance with medical treatment (or Patient Non-adherence)?
Coding Clinic guidance states that if a consulting physician documents a definitive diagnosis that conflicts with the attending physician's notes, the CDI specialist must take this specific action before the final code can be safely assigned.
What is issue a query to the attending physician (to resolve the conflicting documentation)?
When a provider documents a diagnosis but the clinical indicators completely vanish or contradict it, a CDI specialist issues this specific type of query.
What is a clinical validation query?
This indicator measures the average complexity and resource consumption of all patients treated at a hospital.
What is CMI (Case Mix Index)?
When a patient is admitted with both localized cellulitis and an underlying systemic infection, this code must be sequence-checked to determine which is the true principal diagnosis.
What is Sepsis?
Documenting this specific housing status acts as a severe complexity indicator and can directly shift a patient's risk profile due to the extreme barriers it creates for post-discharge care.
What is Homelessness?
A major Coding Clinic update clarified that BMI codes can be captured from a dietitian's or nurse's notes, provided that the attending physician explicitly documents this related medical diagnosis in the chart.
What is Obesity (or Morbid Obesity / Malnutrition)?
When structuring a multiple-choice query, the CDI specialist is fundamentally required to include this specific phrase or option alongside the clinical choices to avoid forcing a provider into picking a predefined diagnosis, ensuring the prompt remains legally non-leading.
What is "Other"? (Alternatively: What is a free-text option?)
Sponsored by NQF and AHRQ, these acronyms represent specific, measurable safety events like accidental punctures or retained foreign objects.
What are PSIs (Patient Safety Indicators)?
Under the official ICD-10-CM Guidelines, this specific clinical document cannot be utilized by a coder to capture secondary diagnoses—even if it explicitly details clinical evaluation, therapeutic treatment, or increased nursing care—because it is generated by a provider who is not legally accountable for establishing the patient's primary diagnosis.
What are nursing, PT/OT progress notes?
(While these notes can provide clinical indicators for a CDI specialist to issue a query, they cannot be used for direct code assignment unless a legally accountable provider documents the condition).
This term describes the unfair, systemic differences in health outcomes among different population groups that CDI departments help track by ensuring accurate demographic and social data capture.
What are Health Disparities (or Health Inequities)?
Per Coding Clinic guidelines regarding "Uncertain Diagnoses," an inpatient coder can report a condition documented as "suspected," "possible," or "probable" as if it exists, provided this specific condition is still present or unresolved at this precise clinical milestone.
What is discharge (or at the time of discharge)?
