Clinical Context
A 52-year-old patient presents to a gastroenterology clinic with a 3-month history of intermittent epigastric pain (R10.13), reflux symptoms consistent with gastro-esophageal reflux disease (K21.9), intermittent nausea (R11.0), and new onset melena or worsening dyspepsia raising concern for peptic ulcer disease (K25.9, K29.70). After outpatient evaluation including history, physical exam, and failure of initial medical therapy, the gastroenterologist schedules an esophagogastroduodenoscopy for diagnostic evaluation. The procedure involves insertion of an upper endoscope through the mouth to visualize the esophagus, stomach, and duodenum, assess mucosal abnormalities, obtain washings or brushings if needed, and consider targeted biopsies. Typical workflow includes pre-procedure consent and sedation assessment, procedure performed in an endoscopy suite or hospital outpatient endoscopy unit, recovery in a monitored recovery area, pathology processing if specimens obtained, and follow-up visit to discuss findings and pathology results.
Coding Specifications
| Modifier | Description | When to Use |
|---|
25 | Significant, separately identifiable E/M service by the same physician on the day of procedure | Use when a distinct evaluation and management visit is performed and documented on the same day as the EGD prior to 43235. |
| 26 | Professional component | Use when billing only the physician professional component separate from the facility or technical component.
| 50 | Bilateral procedure | Not typically applicable to 43235 but included when bilateral-specific modifiers are required for paired organ procedures.
| 51 | Multiple procedures | Use when 43235 is reported with additional distinct endoscopic procedures during the same session to indicate multiple procedures were performed.
| 52 | Reduced services | Use when the service was partially reduced or not completed as documented (for example, aborted procedure documented with partial attempt).
| 53 | Discontinued procedure | Use when the procedure is started but discontinued due to patient instability or other documented reasons before completion.
| 59 | Distinct procedural service | Use to indicate a distinct procedure or service not normally billed together when clinical documentation supports separate services on the same day.
| 62 | Two surgeons | Use when two surgeons work together as primary surgeons on complex cases requiring two physicians; rare for diagnostic 43235 but applicable when documented.
| 76 | Repeat procedure by same physician (note: 76 not in provided list; use closest applicable codes only) | Data not available in the input.
| 78 | Unplanned return to the operating/procedure room for a related procedure during the postoperative period | Use when an unplanned return to the procedure area is required for a related complication.
| 79 | Unrelated procedure or service by the same physician during the postoperative period | Use when a separate unrelated procedure is performed during the global period.
| AS | Physician assistant, nurse practitioner, or clinical nurse specialist services for covered inpatient procedures (use depends on payer) | Use when advanced practice clinicians bill within payer rules alongside supervising physician documentation.
| TC | Technical component | Use when billing only the technical component of the service (facility, equipment, and supplies) separate from the physician professional component.
| JW | Drug amount discarded/not administered | Use when biologic or single-use injectable medications drawn up but not administered and discarded, documented per payer rules.
| XE | Separate encounter | Use to indicate that the service was distinct because it occurred during a separate encounter on the same date of service.
| Taxonomy Code | Specialty | Notes |
|---|
207RG0100X | Gastroenterology Physician | Primary specialty performing diagnostic EGD procedures such as 43235. |
| 207Q00000X | Family Medicine Physician | May perform EGDs in some outpatient procedural settings where trained and credentialed.
| 207R00000X | Internal Medicine Physician | Internists with procedural training may perform EGDs in outpatient or hospital settings.
Related Diagnoses
| ICD-10 Code | Description | Clinical Relevance |
|---|
K21.9 | Gastro-esophageal reflux disease without esophagitis | Common indication for EGD to evaluate persistent reflux symptoms or complications when alarm features are present. |
| K25.9 | Gastric ulcer, unspecified as acute or chronic, without hemorrhage or perforation | EGD is used to visualize ulcers, assess for stigmata of recent bleeding, and obtain biopsies if needed.
| K29.70 | Gastritis, unspecified, without bleeding | EGD can confirm gastritis, determine severity, and obtain biopsies for H. pylori or other etiologies.
| K31.9 | Disease of stomach and duodenum, unspecified | Diagnostic EGD evaluates nonspecific stomach or duodenal disease presenting with dyspepsia or pain.
| R10.13 | Epigastric pain | Common presenting symptom prompting diagnostic upper endoscopy to identify peptic disease or other causes.
| R11.0 | Nausea | Nonspecific symptom that may lead to endoscopic evaluation if persistent or associated with other alarm signs.
| R19.7 | Diarrhea, unspecified | Less specific but may be present with upper GI disorders prompting broader evaluation including EGD when clinically indicated.
