What cholelithiasis ICD codes can I use?
If you're searching for cholelithiasis ICD codes, several options are available, although most of them don't explicitly mention it in their names. Instead, they commonly refer to "Calculus of gallbladder," another term for cholelith. Here are some relevant ICD-10 codes associated with cholelithiasis that you can consider:
- K80.00 - Calculus of gallbladder with acute cholecystitis without obstruction
This ICD-10 code is meant to be used on a patient confirmed to have gallbladder calculus, also known as choleliths or gallstones. These are made up of bile components. In the context of this ICD-10 code, the patient also has acute cholecystitis, meaning they have an inflammation in the gallbladder due to bile build-up. There’s also nothing obstructing the gallbladder, so the gallstones are not causing any obstruction.
- K80.01 - Calculus of gallbladder with acute cholecystitis with obstruction
This is the same as Item 1, but this time, there is an obstruction in the gallbladder.
- K80.10 - Calculus of gallbladder with chronic cholecystitis without obstruction
This is the same as Item 1, but this time, the cholecystitis is chronic, not acute. This means that the swelling/inflammation of the gallbladder continues over time. There are no obstructions, though.
- K80.19 - Calculus of gallbladder with other cholecystitis with obstruction
This is the same as Item 1, but this time, the cholecystitis is chronic, not acute, and there are obstructions.
- K80.20 - Calculus of gallbladder without cholecystitis without obstruction
This is the same as Item 1, but this time, there is not cholecystitis and there are no obstructions.
- K80.80 - Other cholelithiasis without obstruction
This ICD-10 code is meant to be used on a patient confirmed to have a different kind of cholelithiasis. One possible reason why you’d choose this is that the cholelithiasis isn’t in the gallbladder (where it is common), but it is in the common bile duct instead. There’s also no obstruction.
- K80.81 - Other cholelithiasis with obstruction
This is the same as Item 6, but this time, there’s an obstruction.
- K91.86 - Retained cholelithiasis following cholecystectomy
This ICD-10 code is meant to be used on a patient who underwent cholecystectomy (the removal of the gallbladder), but it was confirmed that there are still gallstones present.
