Essential facts and insights about ICD-10 Coding for Pickwickian Syndrome
Use ICD-10 code E66.2 for morbid (severe) obesity with alveolar hypoventilation, ensuring proper documentation in clinical notes.
Additional codes that may be used with this diagnosis
BMI 30.0–39.9

The ICD-10 code for Pickwickian syndrome, also known as obesity hypoventilation syndrome, is E66.2. This code is used when obesity is linked to alveolar hypoventilation.
No, E66.2 and G47.33 should not be coded together if hypoventilation is present. Use E66.2 alone for obesity hypoventilation syndrome.
Documentation must include BMI, evidence of daytime hypercapnia, and link obesity to hypoventilation. ABG results showing pCO2 >45 mmHg are essential.
