Chapter 1 — Certain Infectious & Parasitic Diseases (A00–B99)
Patient admitted with sepsis due to pneumonia. How are the conditions sequenced?
What is sepsis first, followed by the localized infection?
Patient admitted for radiation therapy only for lung cancer. What is sequenced first?
What is Z51.0 (encounter for radiotherapy)?
Anemia due to chronic kidney disease is documented. How is it sequenced?
What is CKD first, then anemia?
Alcohol abuse and alcohol dependence are both documented. Which is coded?
What is dependence?
Hypertension with heart failure is documented. What additional detail is required?
What is the type of heart failure?
Sepsis with acute kidney failure is documented. What additional guideline applies?
What is to code severe sepsis and the organ dysfunction?
Patient has colon cancer with liver metastases. Which site is sequenced first?
What is the primary malignancy (colon)?
Anemia due to chemotherapy is documented. What is sequenced first?
What is the adverse effect of antineoplastic therapy?
Opioid dependence with opioid-induced mood disorder is documented. How is it coded?
What is the substance dependence code with the substance-induced disorder?
Hypertension with CKD requires identification of this.
What is the CKD stage?
Sepsis documented as “probable” on inpatient admission. How is it coded?
What is coded as confirmed/established?
Cancer has been eradicated and patient presents for follow-up. What is coded?
What is personal history of malignant neoplasm?
Type 2 diabetes with diabetic neuropathy. What coding rule applies?
What is combination coding for diabetes with complications?
Patient in sustained remission from cocaine dependence. What guideline applies?
What is to use remission codes only when clearly documented?
Acute on chronic systolic heart failure is documented. How is this coded?
What is acute on chronic heart failure with specificity?
Hospital-acquired C. diff develops after admission. What POA indicator applies?
What is POA = N?
Pathology cannot determine if tumor is benign or malignant. Which behavior is coded?
What is neoplasm of uncertain behavior?
Type 2 diabetes with CKD stage 4. What additional code is required?
What is the CKD stage?
Epilepsy is documented without further detail. What information is required?
What is intractable vs not intractable?
Acute respiratory failure with pneumonia is documented. What is sequenced first?
What is acute respiratory failure?
Sepsis is ruled out; only fever and tachycardia remain. What is coded?
What are signs and symptoms only?
Patient admitted for anemia due to malignancy. What guideline determines sequencing?
What is to code the malignancy first, then the anemia?
Type 1 diabetes on insulin. Should long-term insulin be coded?
What is no — insulin use is inherent to Type 1 diabetes?
Parkinson’s disease with dementia is documented. How are codes sequenced?
What is Parkinson’s first, then dementia?
COPD with acute exacerbation and lower respiratory infection is documented. What guideline applies?
