I search the index for Pneumonia and chose the code that specified (acute)(double)(migratory) (purulent)(septic)(unresolved) – J18.9. and verified in the tabular index. ICD-10-CM guidelines state cough and shortness of breath are symptoms associated with pneumonia and cannot be assigned additional codes. Inpatient scenario – 1 Code: E86.0 – Dehydration. Code: 148.91 – Unspecified atrial fibrillation. Code: J44.9 – Chronic obstructive pulmonary disease, unspecified. The main diagnosis is Dehydration. Secondary diagnose are Atrial fibrillation and COPD. To find these codes I search the index for each term and verified them in the tabular index. ICD- 10-CM guidelines state that nausea, vomiting, and fatigue associated with a disease process (Dehydration) cannot be assigned as additional codes.
