ICD-10 keeps 3 code choices for you.
When your anesthesiologist is involved with a case to correct an umbilical hernia, you start your diagnosis selection by verifying the presence or absence of obstruction or gangrene.
ICD-9: You currently have three code choices for umbilical hernia:
ICD-10: When you begin using ICD-10 codes on Oct.1, 2014, the base code for a diagnosis of umbilical hernia will change to K42 (Umbilical hernia). Again, depending on the presence or absence of obstruction or gangrene, you have three code choices to more accurately report the condition. You can report a diagnosis of umbilical hernia with these three codes in ICD-10:
If you look at the descriptor to K42.0, you’ll notice that this descriptor has been made more specific than its ICD-9 predecessor, namely 552.1 as it is specific for umbilical hernia with obstruction and specifically mentions that there is no gangrene.
Caveats: You’ll have to use K42.0 if the surgeon diagnoses incarcerated umbilical hernia, irreducible umbilical hernia, or strangulated umbilical hernia when no gangrene is mentioned in the documentation. Use K42.9 when the diagnosis is umbilical hernia NOS.
