Learn ICD and CPT Codes for Cholelithiasis and Gallstones. Radiology coding has all types of charts from x-rays, Ultrasound, CT, MRI, Nuclear Medicine etc, to code. Ultrasound procedures are the most commonly found charts in radiology.

Whenever a patient comes with abdomen pain, physicians prefer to go for Ultrasound. Abdomen ultrasound is done either limited or complete.

Complete ultrasound (76700) includes all eight organs including Gallbladder, Liver, Spleen, Pancreas, Right Kidney, Left Kidney, Aorta, Inferior Vena Cava and Common Bile Duct. However, a physician can also order Limited Ultrasound (76705) to check only single organ or single quadrant.

Abdomen is divided into four quadrants. Right upper quadrant of abdomen includes gallbladder which has been studied mainly when the patient is having right upper quadrant pain. The main diagnosis for gallbladder includes cholelithiasis or cholecystitis.

CPT Code for Gallbladder Treatment Procedures

Once the diagnosis is confirmed, doctors use following CPT surgical procedures for the treatment of such disorders:
  • CPT Code 47562 Laparoscopy, Surgical; Cholecystectomy.
  • CPT Code 47563 Laparoscopy, Surgical; Cholecystectomy with Cholangiography.
  • CPT Code 47564 Laparoscopy, Surgical; Cholecystectomy with Exploration of Common Duct.
  • CPT Code 47570 Laparoscopy, Surgical; Cholecystoenterostomy.
  • CPT Code 47579 Unlisted Laparoscopy Procedure, Biliary tract.
These laparascopy surgical procedures are done mainly with cholecystectomy to remove the gallbladder. Removal of gallbladder can treat many of the disorder especially the neoplasm.

ICD 9 Codes for Cholelithiasis, Gallstones Pancreatitis

The ICD 9 codes for cholelithiasis are mostly used during coding such charts. Cholelithiasis is presence of calculi in gallbladder which is also called as gallstones.

ICD 9 Codes for Gallstones

Gallstones can cause obstruction in the gallbladder. Cholecystitis may be acute or chronic, which generally cause inflammation of gallbladder. While coding icd 9 codes for cholelithiasis one has to check the presence of cholecystitis has well, since there are some combination codes for both in icd 9 code book. Let’s have a look at the ICD 9 code for cholelithiasis and similar diagnoses.
  • 574.00 Calculus of gallbladder with acute cholecystitis; without mention of obstruction.
  • 574.10 Calculus of Gallbladder with other cholecystitis; without mention of obstruction.
  • 574.20 Calculus of Gallbladder without mention of cholecystitis; without mention of obstruction.
  • 574.30 Calculus of Bile Duct with acute cholecystitis; without mention of obstruction.
  • 574.40 Calculus of Bile Duct with (chronic) cholecystitis; without mention of obstruction.
  • 574.60 Calculus of Gallbladder and bile duct with acute cholecystitis; without mention of obstruction.

ICD 9 Codes for Cholelithiasis

The specific ICD 9 code for Cholelithiasis is 574.20, without any obstruction and cholecystitis. All other ICD 9 codes are having a combination of obstruction or cholecystitis with cholelithiasis. Hence, medical biller should be more careful with searching a code. Most of the times coders land up coding individual code for cholelithiasis (574.20) and cholecystitis unspecified (575.10) which is not correct, as we have a combination code for these diagnosis (574.00 and 574.01).

Same thing goes with the Calculus of bile duct which has combination code with ICD 9 code for cholelithiasis and with cholecystitis (574.30, 574.40, 574.60). Whenever there is a presence of cholelithiasis, calculus in bile duct and cholecystitis in the report, one should not code them individually since we have combination code for them (574.60).

The main symptoms causing this diagnosis are generally a pain in right upper quadrant of the abdomen (789.01). The pain is generally followed by nausea and vomiting (787.01) which can lead to cholecystitis and cholelithiasis. Hence when the patient comes with pain, nausea and vomiting physicians tried to look for gallstones and cholecystitis in the pathology report.
