Crystal's MCW Coder HubCPT 43245 — EGD with Dilation of Gastric Outlet for Obstruction
Code Snapshot
Full Description: Upper gastrointestinal endoscopy including esophagus, stomach, and either the duodenum and/or jejunum as appropriate; with dilation of gastric outlet for obstruction (e.g., balloon, guide wire, bougie)
Global Period: 000 (Zero Days) | wRVU (2024): ~3.50 | Assistant Surgeon: Not Payable Category: Surgery — Digestive System | Specialty: Gastroenterology / General Surgery
🔬 Clinical Overview
CPT 43245 describes a therapeutic upper gastrointestinal endoscopy (EGD) in which the endoscopist advances a flexible endoscope transorally through the esophagus and stomach to the level of the gastric outlet — the pylorus, pyloric channel, or proximal duodenum — and performs mechanical dilation to relieve obstruction.
The gastric outlet is the functional passage between the stomach and the duodenum controlled by the pyloric sphincter. When narrowed by benign or malignant processes, food and fluid cannot transit normally, resulting in nausea, vomiting, early satiety, and significant nutritional compromise. Endoscopic dilation is the first-line, minimally invasive intervention for amenable cases prior to surgical consideration.
This code is site-specific — it applies only to dilation at the level of the gastric outlet (pylorus / pyloric channel / proximal duodenum). It is not used for esophageal stricture dilation (see 43248 and 43249).
🩺 Procedure Details
Indications
- Adult hypertrophic pyloric stenosis (K31.1)
- Peptic ulcer disease with cicatricial pyloric scarring (K27.7)
- Post-surgical anastomotic stricture (post-gastrectomy, post-Billroth I/II, post-sleeve gastrectomy)
- Malignant gastric outlet obstruction (palliative) — gastric, pancreatic, or duodenal malignancies
- Crohn’s disease with gastroduodenal involvement
- Caustic ingestion with pyloric scarring
- NSAID-induced pyloric stenosis
- Obstruction of the duodenum (K31.5)
Technique / Equipment
The procedure is performed under conscious sedation or monitored anesthesia care (MAC), typically with the patient in the left lateral decubitus position.
Tools used may include:
- Through-the-scope (TTS) balloon dilators (most common) — hydrostatic balloon advanced through the endoscope channel and inflated across the stenosis under direct visualization ± fluoroscopic guidance
- Guide wire-assisted dilation — guide wire passed through the stricture; sequential dilators passed over wire
- Bougie dilators — tapered flexible dilators passed under fluoroscopic guidance
Procedural steps (TTS balloon, typical):
- Diagnostic survey of esophagus, stomach, and duodenum on advancement
- Identify the obstructing lesion at the gastric outlet
- Advance balloon catheter through the working channel across the stricture
- Inflate balloon to target diameter (typically 10-20 mm for pyloric dilation) under direct vision ± fluoroscopy
- Hold inflation for 30-60 seconds; may perform serial dilations
- Deflate and remove balloon; inspect dilation site for bleeding or perforation
- Document pre- and post-dilation diameter, technique, and any complications
Fluoroscopy
Fluoroscopic guidance is sometimes used concurrently, particularly for complex or tight strictures. When performed, separate reporting of fluoroscopy may be appropriate depending on payer policy and documentation. Some payers bundle fluoroscopy guidance into 43245; verify payer-specific rules.

✅ Includes (Bundled Into This Code)
Per CPT convention and NCCI policy, the following are included in 43245 and may not be separately reported:
- Diagnostic EGD (43235) — When a surgical/therapeutic endoscopy is performed, the diagnostic endoscopy is inherently included. The diagnostic survey is always performed as the first step of a surgical endoscopy.
- Introduction and advancement of the endoscope through the esophagus, stomach, and duodenum/jejunum
- Endoscopic visualization of the gastric outlet, pylorus, and duodenum
- Moderate (conscious) sedation — effective January 1, 2017, moderate sedation is no longer separately reportable when performed by the operating physician for these procedures. When performed by a different provider (anesthesiologist/CRNA), that provider reports their own code.
- Balloon inflation and dilation mechanics at the gastric outlet
- Fluoroscopic guidance when routinely included per payer policy (verify payer-specific rules)
- Standard irrigation/aspiration performed as part of the procedure
- Topical pharyngeal anesthesia
- Specimen handling fees in the facility setting (separate specimen handling codes are facility-side)

Site Differentiation — Key to Code Selection
- 43245 = Dilation at the gastric outlet (pylorus / pyloric channel / proximal duodenum)
- 43248 = Dilation at the esophagus using guide wire technique
- 43249 = Dilation at the esophagus using balloon (<30 mm)
Never use 43245 for esophageal stricture dilation. Documentation must clearly state the site of dilation.
🏥 ICD-10-CM Diagnosis Codes
The following ICD-10-CM codes represent the most common primary diagnoses supporting medical necessity for 43245. Documentation must establish the presence of gastric outlet obstruction or high-grade stenosis.
Benign / Non-Malignant Causes
| ICD-10-CM | Description | HCC (v28) | HCC (v24) | Notes |
|---|---|---|---|---|
| K31.1 | Adult hypertrophic pyloric stenosis | ❌ N/A | ❌ N/A | Most common benign indication; distinguish from infantile pyloric stenosis (Q40.0) |

| K31.3 | Pylorospasm, not elsewhere classified | ❌ N/A | ❌ N/A | Functional spasm; less commonly requires dilation |
| K31.5 | Obstruction of duodenum | ❌ N/A | ❌ N/A | Proximal duodenal obstruction; confirm site is accessible endoscopically |
| K31.89 | Other specified diseases of stomach and duodenum | ❌ N/A | ❌ N/A | Use for post-ulcer cicatricial narrowing, NSAID-related pyloric stricture, or other specified causes not elsewhere classified |

| K50.819 | Crohn’s disease of small intestine with unspecified complications | ❌ N/A | ❌ N/A | Use when active complications are documented but unspecified |
Malignant Causes (Palliative Dilation)
| ICD-10-CM | Description | HCC (v28) | HCC (v24) | Notes |
|---|---|---|---|---|
| C16.0 | Malignant neoplasm of cardia | ✅ HCC 10 | ✅ HCC 11 | Gastric cardia cancer with downstream GOO |
| C16.3 | Malignant neoplasm of pylorus | ✅ HCC 10 | ✅ HCC 11 | Primary pyloric malignancy; most direct cause of malignant GOO |
| C16.4 | Malignant neoplasm of pyloric antrum | ✅ HCC 10 | ✅ HCC 11 | Antral carcinoma with outlet obstruction |

HCC Coding Tip
When malignancy is the underlying etiology for gastric outlet obstruction, the malignancy code is the principal/primary diagnosis — not a symptom code. Capture the malignancy code (e.g., C16.3) as the reason for the encounter. The HCC map above reflects CMS-HCC v28 (2024) and v24 (legacy). Confirm mappings annually as CMS revises HCC models. CMS HCC v28 2024
Coding Sequencing
For encounters specifically to perform gastric outlet dilation, sequence the condition causing the obstruction (e.g., K31.1 or C16.3) as the principal/first-listed diagnosis. Obstruction symptom codes (nausea, vomiting) are bundled into the underlying condition per ICD-10-CM guidelines and are not separately reported.
🏗️ ICD-10-PCS Crosswalk (Inpatient Coding)
When 43245 is performed in an inpatient setting, ICD-10-PCS codes are assigned instead of CPT codes. The following ICD-10-PCS codes correspond to endoscopic dilation of the gastric outlet.
Root Operation: Dilation (7)
Dilation = Expanding an orifice or the lumen of a tubular body part.
ICD-10-PCS Table: 0D7 (Dilation, Gastrointestinal System)
| Character | Position | Value | Meaning |
|---|---|---|---|
| 1 | Section | 0 | Medical and Surgical |
| 2 | Body System | D | Gastrointestinal System |
| 3 | Root Operation | 7 | Dilation |
| 4 | Body Part | 7 | Stomach, Pylorus |
| 5 | Approach | 8 | Via Natural or Artificial Opening Endoscopic |
| 6 | Device | Z or D | Z = No Device (balloon removed) / D = Intraluminal Device (if stent placed) |
| 7 | Qualifier | Z | No Qualifier |
Most Common Codes:
| ICD-10-PCS | Description | When Used |
|---|---|---|
| 0D778ZZ | Dilation of Stomach, Pylorus, Via Natural or Artificial Opening Endoscopic, No Device | Most common — TTS balloon dilation where balloon is removed after dilation; bougie dilation; guide wire-assisted dilation with no device left in situ |
| 0D778DZ | Dilation of Stomach, Pylorus, Via Natural or Artificial Opening Endoscopic, Intraluminal Device | Pyloric stent placed and left in situ (note: stent placement is more commonly coded as Restriction [root op V] or Bypass — verify per operative documentation) |
| 0D768ZZ | Dilation of Stomach, Via Natural or Artificial Opening Endoscopic, No Device | When the dilation is at the gastric body, not specifically at the pylorus |
Warning
PCS Specificity — Pylorus vs. Stomach Body ICD-10-PCS distinguishes between Stomach (body part 6) and Stomach, Pylorus (body part 7). Review operative documentation carefully. If the report specifies the pyloric channel, pyloric valve, or pyloric stricture, assign body part character 7 (Stomach, Pylorus). If it describes a more proximal gastric stricture, character 6 (Stomach) may be appropriate.
Stent Placement
If a self-expanding metallic stent (SEMS) is placed and left across the gastric outlet (common in malignant GOO), the root operation shifts from Dilation (7) to potentially Restriction (V) or Bypass (1) depending on clinical intent. Do not assume 0D778DZ simply because a device is involved — the objective and permanent nature of the device matters. Query the provider if documentation is unclear.
🏨 Associated MS-DRGs (Inpatient)
Because 43245 is a CPT code (outpatient), it does not directly drive DRG assignment. In the inpatient setting, DRG assignment is based on ICD-10-CM diagnoses and ICD-10-PCS procedure codes. The ICD-10-PCS codes for endoscopic gastric outlet dilation (e.g., 0D778ZZ) are generally classified as non-O.R. procedures and therefore do not trigger a surgical DRG on their own. DRG assignment defaults to the medical DRG based on principal diagnosis.
Likely MS-DRGs by Principal Diagnosis (MDC 06 — Digestive System)
| MS-DRG | Title | CC/MCC Status | Common Principal Dx |
|---|---|---|---|
| 391 | Esophagitis, Gastroenterology and Miscellaneous Digestive Disorders with MCC | With MCC | K31.1, K31.89, K31.5 |
| 392 | Esophagitis, Gastroenterology and Miscellaneous Digestive Disorders with CC | With CC | Same as above |
| 393 | Esophagitis, Gastroenterology and Miscellaneous Digestive Disorders without CC/MCC | Without CC/MCC | Same as above |
| 374 | Digestive Malignancy with MCC | With MCC | C16.3, C16.4, C25.0 |
| 375 | Digestive Malignancy with CC | With CC | Same |
| 376 | Digestive Malignancy without CC/MCC | Without CC/MCC | Same |
| 388 | GI Obstruction with MCC | With MCC | K31.5, K31.2 |
| 389 | GI Obstruction with CC | With CC | Same |
| 390 | GI Obstruction without CC/MCC | Without CC/MCC | Same |
DRG Impact of CC/MCC
Always code complications and comorbidities to the highest specificity. A well-coded chart that captures an MCC (e.g., protein-calorie malnutrition E43, acute respiratory failure J96.00, or severe hypovolemia in the context of prolonged vomiting) can shift the DRG from 393→391, with significant reimbursement impact. Malnutrition in particular is commonly underdocumented in gastric outlet obstruction cases and represents a legitimate query opportunity.

🧩 NCCI / Bundling Pearls
- Endoscopy same-session rule: When multiple endoscopic procedures are performed through the same natural orifice on the same day by the same physician, only the highest-valued code is reported unless the additional procedures are at distinct sites or involve a distinct clinical circumstance — and NCCI edits allow separate billing with appropriate modifiers.
- 43235 is always bundled: Never separately report the diagnostic EGD when a therapeutic EGD (43245) is performed at the same session.
- Bilateral not applicable: Endoscopic gastric outlet dilation is a single-site procedure; bilateral modifier is not used.
- Conscious sedation (moderate sedation) bundled since 2017: Per AMA CPT coding changes effective 1/1/2017, moderate sedation codes (99151-99157) are no longer included in EGD codes and are separately reportable only when performed by a different provider than the one performing the EGD.
📋 Coding Examples
Example 1 — Classic Benign Pyloric Stenosis
Clinical Scenario: A 58-year-old male presents with progressive nausea, vomiting, and 20-lb weight loss over 3 months. EGD reveals a fibrotic pyloric channel stenosis secondary to long-standing peptic ulcer disease. The gastroenterologist performs TTS balloon dilation (15 mm balloon, two passes) with good post-dilation result. No bleeding or perforation noted. The procedure is performed in an outpatient endoscopy center.
Codes:
- CPT: 43245 — EGD with dilation of gastric outlet for obstruction
- ICD-10-CM (primary): K31.1 — Adult hypertrophic pyloric stenosis
- ICD-10-CM (secondary): K27.7 — Chronic peptic ulcer, site unspecified, without hemorrhage or perforation (if documentation supports)
- HCC impact: None for K31.1 or K27.7
Example 2 — Malignant Gastric Outlet Obstruction (Palliative)
Clinical Scenario: A 72-year-old female with known stage IV antral gastric cancer presents for palliative endoscopic dilation of her pyloric obstruction causing refractory vomiting. The advanced endoscopist passes a TTS balloon and dilates the malignant pyloric stricture to 12 mm. The patient has documented protein-calorie malnutrition. Procedure performed in the hospital outpatient department.
Codes:
- CPT: 43245 — EGD with dilation of gastric outlet for obstruction
- ICD-10-CM (primary): C16.4 — Malignant neoplasm of pyloric antrum (HCC 10 v28 / HCC 11 v24)
- ICD-10-CM (secondary): E43 — Unspecified severe protein-calorie malnutrition (MCC — significant DRG driver if inpatient)
- HCC impact: C16.4 captures HCC; E43 is HCC 21 (v28)
Example 3 — Post-Bariatric Anastomotic Stricture
Clinical Scenario: A 45-year-old female, 8 months post-Roux-en-Y gastric bypass, presents with progressive dysphagia to solids and regurgitation. EGD confirms a tight gastrojejunal anastomotic stricture. Surgeon performs sequential TTS balloon dilation (10 mm → 12 mm). The procedure is documented as dilation of the gastric outlet (gastrojejunal anastomosis).
Codes:
- CPT: 43245 — EGD with dilation of gastric outlet for obstruction
- ICD-10-CM (primary): K91.89 — Other postprocedural complications and disorders of digestive system (anastomotic stricture)
- ICD-10-CM (secondary): Z98.84 — Bariatric surgery status (history code)
- HCC impact: None
Anastomotic Stricture vs. Esophageal Stricture
Post-Bariatric In post-bariatric patients, the site of stricture matters. The gastrojejunal anastomosis is considered the “gastric outlet” equivalent and 43245 is appropriate. If the stricture is at the esophagogastric junction or within the narrow gastric sleeve, a different code may be warranted — review operative report and endoscopy findings carefully.
Example 4 — Inpatient Admission, Concurrent Biopsy at Separate Site (Same Session)
Clinical Scenario: A 65-year-old male admitted for gastric outlet obstruction of unclear etiology. EGD performed in the hospital. Gastroenterologist dilates the pyloric stricture (gastric outlet) with a 15 mm TTS balloon. During the same session, suspicious mucosal irregularity is noted in the mid-esophagus; biopsies are taken from the esophageal lesion for separate clinical evaluation.
Codes (Outpatient/Professional):
- CPT (primary): 43245 — EGD with dilation of gastric outlet
- CPT (secondary): 43239-59 — EGD with biopsy, at a distinct anatomical site (esophagus) for a separate clinical indication (modifier 59 or XS to override NCCI bundle)
- ICD-10-CM: K31.1 (primary), secondary code for esophageal finding if established
ICD-10-PCS (Inpatient):
- 0D778ZZ — Dilation of Stomach, Pylorus, Via Natural or Artificial Opening Endoscopic, No Device
- 0DBP8ZX — Excision of Esophagus, Via Natural or Artificial Opening Endoscopic, Diagnostic (biopsy)
💡 Coding Pearls & Clinical Tips
Documentation Requirements for Medical Necessity Payers require the following in the operative and/or clinical notes to support 43245:
- Identification of the site of obstruction (pylorus, pyloric channel, proximal duodenum — not esophagus)
- Clinical indication/underlying diagnosis (e.g., pyloric stenosis, post-surgical stricture, malignant obstruction)
- Pre-dilation diameter (if fluoroscopy used) or endoscopic assessment of narrowing severity
- Technique used (balloon size and inflation pressure OR bougie size OR guide wire + dilator)
- Post-dilation assessment (improved passage, complications, mucosal status)
Distinguish from Esophageal Dilation
Payer audits frequently target incorrect site coding. 43245 = gastric outlet only. If the report describes esophageal balloon dilation, the appropriate code is 43249 (<30 mm) or 43248 (over guide wire). A single EGD note may involve dilation at two separate sites — review carefully and assign codes per site with appropriate modifiers.
Malnutrition Query Opportunity (Inpatient)
Patients with gastric outlet obstruction — especially those with prolonged vomiting, weight loss, or poor oral intake — frequently meet clinical criteria for malnutrition. If the attending’s documentation doesn’t specify the type and severity, a compliant physician query is appropriate. Capturing severe malnutrition (E43) or moderate malnutrition (E44.0) can significantly impact DRG weight and case mix index.
HCC Capture — Malignant GOO
Place of Service Matters
While 43245 has the same descriptor regardless of setting, reimbursement differs significantly between facility (hospital outpatient/ASC) and non-facility (office) settings due to different total RVU calculations. Outpatient endoscopy centers and hospital outpatient departments use the facility rate. True in-office EGD (rare for this procedure) uses the non-facility rate.
