✍️ Sample CCDS Questions & Answers

1. What does a high CC and MCC capture rate indicate about a CDI program?
The CDI program is effectively identifying and documenting secondary diagnoses

A high CC/MCC capture rate reflects that the CDI program is successfully identifying and ensuring documentation of significant secondary diagnoses that affect patient severity and resource utilization.

2. How do pericarditis and myocarditis differ in terms of CDI documentation requirements?
Both have distinct ICD-10-CM categories and both benefit from etiology documentation

Pericarditis and myocarditis involve different anatomic structures and have distinct ICD-10-CM categories; documenting etiology (viral, bacterial, autoimmune) for both enables more specific code assignment.

3. Which clinical documentation element would MOST strongly support a query for septic shock in a patient who is already coded with sepsis?
Documentation of vasopressor administration to maintain hemodynamic stability AND lactate above 2 mmol/L despite resuscitation

Septic shock requires both vasopressor dependence for MAP maintenance AND lactate above 2 mmol/L despite adequate fluid resuscitation. Both elements must be documented and cited in the query to support the septic shock diagnosis and R65.21 coding.

4. Under Sepsis-3, the term 'severe sepsis' has been eliminated as a clinical definition. How does this affect ICD-10-CM coding practice?
ICD-10-CM still uses R65.20/R65.21 for severe sepsis and septic shock, which are coded based on physician documentation regardless of Sepsis-3 terminology

Although Sepsis-3 eliminated 'severe sepsis' as a clinical term, ICD-10-CM retains R65.20 (severe sepsis without septic shock) and R65.21 (severe sepsis with septic shock). Coding follows physician documentation.

5. What documentation is required to code heart failure as 'systolic' rather than unspecified in ICD-10-CM?
Physician documentation of systolic heart failure

ICD-10-CM requires physician documentation of systolic heart failure; clinical findings and test results alone are insufficient for code assignment by coders.

6. A patient undergoes a laparoscopic cholecystectomy that is converted to an open procedure. How should this be coded in ICD-10-PCS?
Code only the open approach since it was the completed procedure

Per ICD-10-PCS guidelines, when a procedure is converted from a laparoscopic to an open approach, only the open approach procedure code is assigned. The laparoscopic portion that did not complete the intended procedure is not separately coded.
