CPT code 43238 examines the esophagus, stomach, OR duodenum, while 43242 examines the esophagus, stomach AND duodenum/jejunum during an esophagogastroduodenoscopy (EGD).
What is the CPT code for upper endoscopic ultrasound?
CPT 43259 is the code for upper endoscopic ultrasound (EUS) performed during an esophagogastroduodenoscopy (EGD).
This code covers the endoscopic ultrasound examination limited to the esophagus, stomach, or duodenum, and adjacent structures. According to the American Medical Association, 43259 also includes transendoscopic ultrasound-guided fine-needle aspiration/biopsy when performed during the same session.
What is procedure code 43238?
Procedure code 43238 describes an esophagogastroduodenoscopy (EGD) with transendoscopic ultrasound-guided intramural or transmural fine-needle aspiration/biopsy, limited to the esophagus, stomach, or duodenum.
Here's the thing: this code gets used when the endoscopist looks at one or two of these structures and takes biopsies from lesions or masses in those spots. The American Society for Gastrointestinal Endoscopy (ASGE) makes it clear that 43238 doesn't cover the jejunum or any ultrasound work beyond the listed structures.
What is the CPT code for lower endoscopic ultrasound?
CPT code 43237 is used for a lower endoscopic ultrasound (EUS) limited to the esophagus, stomach, or duodenum during an EGD.
Now, unlike 43242—which does include the jejunum—43237 stops at those three structures. The Centers for Medicare & Medicaid Services (CMS) points out this code is typically reserved for cases where the focus stays strictly in the upper GI tract.
What is the CPT code for needle biopsy of the pancreas?
CPT code 48102 is used for a needle biopsy of the pancreas, often guided by endoscopic ultrasound (EUS).
Honestly, this is one of those codes you tack on top of the EUS guidance code (like 43238 or 43242) when you need to pull tissue from the pancreas. The Society of Interventional Radiology (SIR) stresses that both the imaging and biopsy can be billed separately when the medical record shows it was medically necessary.
Can CPT codes 43239 and 43249 be billed together?
CPT codes 43239 and 43249 cannot be billed together because they represent overlapping components of an upper GI endoscopy.
That said, the National Correct Coding Initiative (NCCI) treats these codes as mutually exclusive. If both show up on a claim, payers will bundle them and adjust reimbursement to avoid paying twice for the same endoscopic work.
What does CPT code 45378 mean?
CPT code 45378 describes a diagnostic colonoscopy performed proximal to the splenic flexure, including specimen collection.
This code covers procedures that go past the splenic flexure in the colon—often including biopsies or washing. It's the go-to for colorectal cancer screening and surveillance, though the American Gastroenterological Association (AGA) cautions against using it for screening colonoscopies that reach the terminal ileum.
Why would you need an endoscopic ultrasound?
An endoscopic ultrasound (EUS) is used to evaluate symptoms like abdominal pain, assess the extent of digestive or lung diseases, and clarify findings from imaging studies such as CT or MRI.
According to the Mayo Clinic, EUS really shines when it comes to spotting pancreatic lesions, staging GI cancers, and guiding fine-needle biopsies of suspicious masses. (Frankly, it's one of the most precise tools we've got.)
What is the CPT code for Esophagogastroduodenoscopy?
CPT code 43235 is used for a diagnostic esophagogastroduodenoscopy (EGD) without additional interventions.
If the endoscopist takes biopsies or does other procedures during the EGD, you'd switch to more specific codes like 43239 (with biopsy) or 43242 (with EUS). The AMA CPT Editorial Panel keeps these codes separate so billing matches what actually happened in the procedure room.
What is the difference between CPT code 43237 and 43259?
CPT 43237 examines one or two structures (esophagus, stomach, or duodenum), while 43259 examines all three structures during EUS.
The AMA spells out that 43259 is the more thorough option, usually picked when the endoscopist needs to check the whole upper GI tract in one go. That difference matters for both billing and what you have to document.
What is Transendoscopic?
Transendoscopic refers to a procedure performed through an endoscope, such as ultrasound-guided fine-needle aspiration or biopsy.
This technique lets doctors image and sample tissue in real time from inside the GI tract. The ASGE calls it a game-changer because it cuts down on external punctures and boosts diagnostic precision. (And honestly, it’s way safer for patients.)
What is the CPT code for Cystogastrostomy?
CPT code 48520 is used for a cystogastrostomy, a procedure to drain a pancreatic pseudocyst into the stomach.
This code covers creating an internal drainage route, either endoscopically or surgically. The Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) notes that 48520 can sometimes be billed alongside codes like 43242 (EUS) when both services are part of the same procedure.
What is the purpose of esophagoscopy?
An esophagoscopy allows direct visualization of the esophagus to diagnose conditions like strictures, tumors, or inflammation.
During the procedure, a flexible endoscope travels down the esophagus to inspect the lining and grab biopsies if needed. The American Academy of Otolaryngology-Head and Neck Surgery says it’s a must for evaluating swallowing problems, GERD, and esophageal cancer.
How common is autoimmune pancreatitis?
Autoimmune pancreatitis affects fewer than one in 100,000 people, with a higher prevalence in individuals aged 50–60.
Men get hit about twice as often as women. The Mayo Clinic reports this type of pancreatitis usually responds well to steroids, which helps doctors tell it apart from other forms of the disease.
Can you do a biopsy on the pancreas?
Yes, a biopsy can be performed on the pancreas using fine-needle aspiration (FNA) or core biopsy techniques.
These days, most pancreatic biopsies get guided by endoscopic ultrasound (EUS) for pinpoint accuracy. After the tissue sample is collected, it heads to the lab for analysis—usually within a few days. The American Cancer Society stresses that biopsies are crucial for confirming pancreatic cancer and mapping out treatment plans.
What is the ICD 10 code for pancreatitis?
ICD-10 code K85.9 is used for unspecified acute pancreatitis.
If you need more detail, you can drill down to K85.0 (idiopathic acute pancreatitis) or K85.2 (alcohol-induced acute pancreatitis). The CDC maintains the ICD-10-CM code set, which keeps providers on the same page for billing and documentation.
