Summary & Overview
CPT 0813T: Endoscopic Gastric Balloon Adjustment
CPT code 0813T designates an endoscopic gastric balloon adjustment performed via a flexible endoscope inserted through the mouth to alter the volume of a gastric balloon for weight loss. The code captures a targeted, minimally invasive adjustment procedure distinct from primary balloon placement or removal. Nationally, this service matters as gastric balloon therapies and their maintenance procedures are increasingly used as intermediate, non-surgical weight-management options, influencing coverage decisions and utilization trends across commercial insurers and Medicare.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical context for the procedure, typical sites of service, common modifiers associated with endoscopic and ambulatory procedures, and what is available about payer coverage patterns. The publication outlines benchmarks where available, summarizes relevant policy and coding considerations that affect claims processing, and explains how the service relates clinically to obesity management pathways. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 0813T describes an endoscopic procedure in which a flexible endoscope is passed through the mouth to access the stomach and adjust the volume of an implanted gastric balloon to assist with weight loss. This procedure is minimally invasive and intended to modify the internal balloon volume to optimize satiety and weight-management outcomes.
-
Service Type: Endoscopic gastric balloon adjustment
-
Typical Site of Service: Ambulatory surgical center or hospital outpatient department, performed under sedation with direct endoscopic visualization.
Clinical & Coding Specifications
Clinical Context
A 42-year-old patient with persistent obesity who previously underwent endoscopic intragastric balloon placement presents for planned volume adjustment of the existing gastric balloon. The patient reports recent weight plateaus and increased intolerance to satiety. The clinical workflow includes pre-procedure evaluation (vital signs, review of recent weight trajectory, assessment for contraindications such as gastric ulceration or device migration), informed consent, brief fasting, and administration of moderate sedation by an anesthesia provider or endoscopist-directed sedation per facility policy. The provider inserts a flexible endoscope through the mouth to visualize the stomach and confirm balloon position and integrity, then accesses the balloon port and adjusts the balloon fill volume (increase or decrease) by adding or removing saline or sterile fluid. After adjustment the stomach is re-inspected for leaks, mucosal injury, or impingement. The patient is recovered, given post-procedure discharge instructions, and scheduled for follow-up to monitor symptoms, tolerance, and weight change. Typical site of service is an ambulatory endoscopy or outpatient surgical center; inpatient adjustment is uncommon but may occur if complications are present.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when work or complexity substantially exceeds typical for a standard balloon volume adjustment (document rationale). |
23 | Unusual anesthesia | Use when general anesthesia is required for the endoscopic adjustment rather than typical sedation. |
51 | Multiple procedures | Use when the adjustment is billed on the same day as additional unrelated procedures performed by the same provider. |
52 | Reduced services | Use when the procedure is partially reduced or not completed as planned (document reason). |
53 | Discontinued procedure | Use when the procedure is started but terminated due to patient instability or unexpected findings. |
62 | Two surgeons | Use when two surgeons work together as primary surgeons during a complex endoscopic adjustment (rare). |
66 | Surgical supervisor-performed procedure | Use when a teaching surgeon acts as the primary surgeon for the procedure. |
73 | Discontinued outpatient hospitalization before anesthesia | Use when the patient is prepared but the outpatient procedure is cancelled after initiation of anesthesia/sedation. |
78 | Unplanned return to the operating/procedural room | Use when the patient returns to the procedural area for a related complication of the original adjustment. |
80 | Assistant surgeon | Use when an assistant surgeon is required and documented. |
81 | Minimum assistant surgeon | Use when a minimal level assistant surgeon is documented and required. |
82 | Assistant surgeon (qualification unavailable) | Use when an assistant is documented but lacks full qualifications. |
AS | Physician assistant, nurse practitioner, or clinical nurse specialist | Use when an APP performs or assists per payer rules and billing requires this modifier. |
QX | CRNA service with qualified non‑physician anesthetist | Use when a certified registered nurse anesthetist performs anesthesia and a separate billing arrangement applies. |
| Taxonomy Code | Specialty | Notes |

| 207L00000X | General Surgery | Bariatric surgeons who manage intragastric balloons as part of weight-loss programs. |
| 2080P0007X | Bariatric Medicine | Physicians specializing in medical management of obesity and intragastric device management. |
| 364S00000X | Anesthesiology | Providers who administer sedation or general anesthesia for endoscopic procedures. |
Related Diagnoses
| ICD-10 Code | Description | Clinical Relevance |
|---|---|---|
E66.01 | Morbid (severe) obesity due to excess calories | Common indication for intragastric balloon placement and subsequent volume adjustments to optimize weight loss. |
E66.9 | Obesity, unspecified | General obesity diagnosis used when more specific coding is not available; supports medical necessity for balloon adjustments. |
E66.3 | Overweight | May be used in follow-up documentation when weight trends change; less common as primary indication for device adjustment. |
K29.70 | Gastritis, unspecified, without bleeding | Gastric mucosal irritation or gastritis is a potential comorbidity to assess prior to adjustment. |
K31.89 | Other disease of stomach and duodenum | Used for reporting other stomach conditions that may affect device tolerance or require inspection during endoscopy. |
