Code Description
CPT 69436 - Tympanostomy (requiring insertion of ventilating tube), local or general anesthesia
This code represents a surgical procedure involving the creation of an opening in the tympanic membrane (myringotomy) with the insertion of a ventilating tube (pressure equalization or PE tube). This code is used when the procedure is performed under local or general anesthesia, typically in an operating room or ambulatory surgery center (ASC) setting.
Key Distinction:
- 69436: Tympanostomy with tube insertion, local or general anesthesia (OR/ASC setting).
- 69433: Tympanostomy with tube insertion, local anesthesia only (Office setting).
- 69440: Revision of tympanostomy (removal and replacement of tube).
- 69420: Myringotomy including aspiration and/or instillation (without tube).

External Cause Codes (Reference: icd10cm_eindex_2025.pdf)
Note: Tympanostomy is typically elective for chronic conditions. External cause codes are generally not assigned unless the condition resulted from an injury (e.g., traumatic perforation requiring tube). Based on the uploaded External Cause Index 2025:
| Category | Code Example | Description from Index |
|---|---|---|
| Place of Occurrence (Y92) | Y92.009 | Private residence (unspecified) |
| Y92.239 | Hospital (unspecified) | |
| Y92.531 | Dentist office | |
| Y92.63 | Factory (building)(premises) | |
| Activity (Y93) | Y93.89 | Activity specified NEC |
| Y93.01 | Walking (on level or elevated terrain) | |
| Y93.61 | Football (American) NOS | |
| Y93.83 | Food preparation | |
| Status (Y99) | Y99.0 | Civilian activity done for income or pay |
| Y99.8 | Leisure activity | |
| Y99.1 | Military activity |
Usage Note: Assign external cause codes per icd10cm_eindex_2025.pdf guidelines only if the medical record documents an external cause (e.g., trauma, barotrauma) leading to the necessity of the procedure. For routine chronic otitis media, external cause codes are not applicable.
Includes
- Myringotomy - Incision into the tympanic membrane
- Tube Insertion - Placement of ventilating/pressure equalization (PE) tube
- Anesthesia - Local or General (OR/ASC setting)
- Aspiration - Removal of fluid from middle ear (if performed)
- Bilateral Procedure - Often performed on both ears (report with modifier 50 or LT/RT)
- Immediate Post-op Care - Recovery room monitoring
Excludes
| Code | Description | Reason |
|---|---|---|
| 69433 | Tympanostomy; local anesthesia | Office setting only |
| 69440 | Revision of tympanostomy | Removal and replacement of existing tube |
| 69448 | Removal of ventilating tube | Removal only |
| 69420 | Myringotomy without tube | No tube inserted |
| 69421 | Myringotomy with general anesthesia | No tube inserted |
| 69601 | Repair of tympanic membrane | Tympanoplasty |
| 69631 | Tympanoplasty without mastoidectomy | More extensive repair |
| 69641 | Tympanoplasty with mastoidectomy | More extensive repair |
Assistant Surgeon Information
| Payer Type | Assistant Payable | Typical Reimbursement |
|---|---|---|
| Medicare | No (Status Indicator 0) | $0.00 |
| Commercial | Varies by contract | Rarely allowed |
| Medicaid | Varies by state | Rarely allowed |
Note:
Medicare and most payers consider this a routine procedure that does not require an assistant surgeon. Billing with modifier 80/81/82 will likely result in denial.
Work RVU Breakdown (2025 Medicare Physician Fee Schedule)
| Component | RVU Value | Description |
|---|---|---|
| Work RVU | 2.56 | Physician work effort |
| Practice Expense RVU | 1.85 | Facility/equipment costs |
| Malpractice RVU | 0.25 | Liability insurance costs |
| Total RVU (Non-Facility) | 4.66 | Office-based setting (Rare for 69436) |
| Total RVU (Facility) | 4.66 | Hospital/ASC setting (Common) |
Note: RVU values may vary by geographic location due to GPCI adjustments. 69436 is predominantly performed in ASC or Hospital Outpatient settings.
MS-DRG Information (Inpatient Procedures)
Important: Tympanostomy tubes are overwhelmingly performed as outpatient or ambulatory surgery center (ASC) procedures. Inpatient admission is rare and usually requires significant comorbidities.
If performed in an inpatient setting, 69436 may map to the following MS-DRGs:
| MS-DRG | Description | Relative Weight (Approx.) |
|---|---|---|
| 068 | Other Ear, Nose, Mouth, Throat Procedures | 1.15 |
| 067 | Other Ear, Nose, Mouth, Throat Diagnoses | 0.95 |
| 064 | Head & Neck Malignancy with Major OR Procedure | 2.85 (If malignancy present) |
CC/MCC Considerations:
- MCC: Severe malnutrition, respiratory failure, tracheostomy
- CC: Asthma, pneumonia, dehydration, anemia

Documentation Requirements
Operative/Procedure Report Must Include:
- Preoperative Diagnosis
- Postoperative Diagnosis
- Procedure Performed (Tympanostomy with tube insertion)
- Anesthesia Type (Local or General)
- Laterality (Left, Right, or Bilateral)
- Tube Type (Short-term, Long-term, T-tube, etc.)
- Fluid Findings (Serous, mucoid, purulent, none)
- Complications (Bleeding, perforation, etc.)
- Post-Procedure Condition (Stable, discharged)
- Hearing Test (If performed intraoperatively)
Key Phrases to Document:
- “Tympanostomy performed”
- “Ventilating tube inserted”
- “General/Local anesthesia administered”
- “Fluid aspirated from middle ear”
- “Bilateral/Unilateral procedure”
- “Patient tolerated procedure well”
Medical Necessity
Indications for 69436:
- Chronic Otitis Media with Effusion (OME) - Persistent fluid > 3 months
- Recurrent Acute Otitis Media (AOM) - 3 episodes in 6 months or 4 in 1 year
- Eustachian Tube Dysfunction - Persistent pressure/pain
- Barotrauma - Inability to equalize pressure
- Complications of Otitis - Mastoiditis, tympanic membrane retraction
- Hearing Loss - Conductive hearing loss due to fluid
Contraindications:
- Active Upper Respiratory Infection - May increase anesthesia risk
- Uncontrolled Bleeding Disorder - Risk of hemorrhage
- Medically Unstable - Cannot tolerate anesthesia
- Single Hearing Ear - Relative contraindication (risk benefit analysis)
Common Denial Reasons
| Denial Code | Reason | Resolution |
|---|---|---|
| CO-50 | Medical necessity | Provide audiogram or tympanogram results |
| CO-97 | Bundled service | Verify not bundled with adenoidectomy (sometimes) |
| CO-16 | Missing information | Submit operative report with anesthesia type |
| CO-22 | Billing/coding error | Verify 69436 vs 69433 (setting/anesthesia) |
| CO-109 | Not covered by payer | Check patient benefits for ENT procedures |
Compliance Considerations
- Setting Verification - 69436 is for OR/ASC (General/Local). 69433 is for Office (Local only). Do not bill 69436 for office procedures.
- Bilateral Billing - Verify payer preference for Modifier 50 vs. LT/RT with units of 2.
- Assistant Surgeon - Do not bill assistant surgeon unless specific payer policy allows (rare).
- Global Period - 0-day global allows billing of post-op visits if unrelated, but routine follow-up is often bundled by payer policy.
- External Causes - Assign per icd10cm_eindex_2025.pdf if trauma is documented.
- Concurrent Procedures - If adenoidectomy (42835) is performed, ensure distinct documentation for each procedure.
Related Procedures
| CPT | Description | Relationship |
|---|---|---|
| 69433 | Tympanostomy; local anesthesia | Office setting alternative |
| 69440 | Revision of tympanostomy | Removal and replacement |
| 69448 | Removal of ventilating tube | Removal only |
| 69420 | Myringotomy without tube | Incision only |
| 69421 | Myringotomy with general anesthesia | Incision only, GA |
| 42835 | Adenoidectomy | Often performed concurrently |
| 42830 | Tonsillectomy | Often performed concurrently |
Clinical Pearls
- Anesthesia Risk - Pediatric patients often require general anesthesia for immobility; adults may tolerate local.
- Tube Types - Short-term tubes extrude spontaneously in 6-12 months; long-term may require removal.
- Water Precautions - Controversial; some providers recommend ear plugs for swimming.
- Otorrhea - Post-op drainage is common; treat with topical antibiotics.
- Hearing Improvement - Most patients experience immediate improvement in conductive hearing loss.
- External Causes - For barotrauma (e.g., diving, flying), document activity for correct ICD-10 coding.
