📖 Clinical Description
31603 describes an emergency surgical procedure to create an opening into the trachea (windpipe) when a patient’s airway is immediately compromised and there is no time for a planned, elective tracheostomy. This is a life-saving intervention performed when the patient is in acute respiratory distress or obstruction and cannot be intubated or ventilated by other means.[1][4][7]
Procedure Steps[1][7]
- Emergency Assessment: The patient presents with acute airway obstruction, stridor, or respiratory failure requiring immediate intervention.
- Incision: The surgeon makes an incision directly into the trachea, typically between the second and third tracheal rings.
- Airway Establishment: An opening is created to allow air to enter the trachea, bypassing any upper airway obstruction.
- Tube Insertion: A tracheostomy tube is inserted to maintain the airway and facilitate ventilation.
- Securing: The tube is secured in place, and the patient is stabilized.
Indications[1][7][10]
- Acute upper airway obstruction (foreign body, trauma, edema, tumor)
- Failed endotracheal intubation with inability to ventilate
- Severe facial or neck trauma compromising the airway
- Anaphylaxis with life-threatening laryngeal edema
- Epiglottitis with impending airway compromise
- Bilateral vocal cord paralysis with acute obstruction
Emergency vs. Planned Distinction[1][7][10]
The critical distinction between 31603 and planned tracheostomy codes (31600-31601) is the urgency and immediacy of the procedure:
| Factor | Emergency (31603) | Planned (31600-31601) |
|---|---|---|
| Timing | Immediate, life-threatening | Scheduled, controlled setting |
| Patient Status | Acute airway compromise | Often intubated, stable |
| Setting | ED, bedside, ICU, OR | Typically OR |
| Definition | ”Patient is immediately imperiled if physician doesn’t perform the procedure”[10] | “Patient may obstruct sometime and physician schedules the procedure”[1] |
🔍 Includes and Inclusions
- Emergency Tracheostomy: Performed under emergent conditions for acute airway rescue[1][4][7]
- Transtracheal Approach: Incision made directly into the trachea (between second and third rings)[1][7]
- All Ages: Code applies to patients of any age (unlike 31601 which is age-specific)[7]
- Life-Saving Intervention: Procedure performed to prevent imminent death from airway obstruction

👨⚕️ Assistant Surgeon (Modifier 80) Payability
Assistant Surgeon Status for Tracheostomy Codes[1]
| Code | Assistant Surgeon Indicator | Payability |
|---|---|---|
| 31600 | 1 | Payment restrictions apply; assistant not typically paid |
| 31601 | 2 | Payment restrictions do NOT apply; assistant may be paid |
| 31603 | 1 | Payment restrictions apply; assistant not typically paid |
| 31605 | 1 | Payment restrictions apply |
| 31610 | 1 | Payment restrictions apply |
Assistant Surgeon Modifiers
| Modifier | Description |
|---|---|
| 80 | Assistant Surgeon (physician) |
| 81 | Minimum Assistant Surgeon |
| 82 | Assistant Surgeon (when qualified resident not available) |
| AS | Non-Physician Assistant at Surgery (PA, NP, RNFA) |
Documentation Requirements for Teaching Hospitals
When the surgery is performed in a teaching hospital, documentation must support one of the following for assistant surgeon reimbursement:
- A statement that no qualified resident was available to perform the service
- A statement indicating that exceptional medical circumstances exist
- A statement indicating the primary surgeon has an across-the-board policy of never involving residents in patient care
Clinical Justification for Assistant
Because 31603 has an indicator 1, payers generally will not reimburse for an assistant surgeon. In rare extenuating circumstances, documentation would need to clearly support medical necessity.
💰 Work RVU (wRVU) and Reimbursement
Work RVU Information
The Work Relative Value Units (wRVU) for 31603 are updated annually by CMS. For current values:
- 2026 Reference: Consult the most recent CMS Physician Fee Schedule (PFS) Final Rule or the AMA RBRVS DataManager[2][5]
- Reimbursement Factors: Final payment determined by:

| Efficiency Adjustment | -2.5% applied to work RVUs for non-time-based codes, including 31603[2][5][8] |
Important Note: CMS has finalized a -2.5% productivity/efficiency adjustment applied to work RVUs for approximately 7,700 non-time-based codes, including emergency tracheostomy. This will affect the 2026 wRVU values compared to prior years.[2][8]
Medicare Administrative Contractor (MAC) Considerations
Reimbursement may vary based on:
- Local Coverage Determinations (LCDs) in your region
- Specific MAC policies regarding medical necessity
- Documentation requirements for emergency procedures
📋 Documentation Requirements
To support billing of 31603, the operative report should clearly document:[1][7][10]
- Emergency Nature: Explicit documentation that the procedure was emergent and life-saving
- Indication: Specific reason for emergency airway intervention (e.g., “acute airway obstruction,” “failed intubation,” “impending respiratory arrest”)
- Timing: Description of the urgent/emergent circumstances
- Incision Site: Documentation that incision was transtracheal (between 2nd-3rd tracheal rings) - critical for differentiating from 31605[7][10]
- Findings: Description of airway anatomy and any obstruction encountered
- Tube Type: Size and type of tracheostomy tube inserted
- Patient Stability: Description of patient’s condition before and after procedure
Critical Documentation Elements[1][7]
| Element | Why It Matters |
|---|---|
| Emergency Justification | Supports use of 31603 vs. planned codes |
| Incision Location | Distinguishes 31603 (transtracheal) from 31605 (cricothyroid) |
| Timing Description | Documents emergent nature |
| Patient Condition | Supports medical necessity |

📝 Coding Examples and Scenarios
Example 1: Emergency Tracheostomy for Acute Airway Obstruction
Scenario: A 65-year-old patient presents to the emergency department with sudden onset of stridor and respiratory distress due to a large laryngeal tumor. Attempts at intubation fail. The otolaryngologist performs an emergency transtracheal tracheostomy at the bedside. Coding:
- 31603 (Tracheostomy, emergency procedure; transtracheal)
- J38.6 (Stenosis of larynx) or appropriate tumor diagnosis
- Rationale: The procedure was emergent, life-saving, and performed transtracheally.[1][4][7]
Example 2: Emergency Tracheostomy in Infant
Scenario: A 6-month-old infant with severe epiglottitis presents with impending airway obstruction. Emergency tracheostomy is performed in the operating room. Coding:
- Correct: 31603 (Tracheostomy, emergency procedure; transtracheal)
- Incorrect: 31601 (Planned tracheostomy, under 2 years)
- Rationale: Even though the patient is under 2 years, the emergent nature requires 31603, not the planned pediatric code.[7]
Example 3: Emergency Tracheostomy with Modifier 63 for Neonate
Scenario: A 3-week-old neonate weighing 3.1 kg with congenital airway anomaly develops acute respiratory distress requiring emergency tracheostomy. Coding:
- 31603 - 63 (Tracheostomy, emergency procedure; transtracheal, procedure on infant less than 4 kg)
- Appropriate congenital anomaly diagnosis
- Rationale: Modifier 63 indicates the increased complexity of performing this emergency procedure on an extremely small infant.[1]
Example 4: Emergency Tracheostomy with Foreign Body Removal
Scenario: A patient aspirates a foreign body causing complete airway obstruction. The surgeon performs emergency tracheostomy and removes the foreign body through the tracheostomy incision. Coding:
- 31603 (Tracheostomy, emergency procedure; transtracheal)
- 31635 (Bronchoscopy with removal of foreign body) - with appropriate modifier
- Rationale: Both procedures performed; check payer policy for bundling and modifier requirements.
Example 5: Emergency vs. Planned Distinction - Same-Day Decision
Scenario: An ENT evaluates a patient with a neck abscess and mild stridor. The patient is scheduled for planned tracheostomy the next day. Overnight, the patient’s condition deteriorates with severe stridor, and the ENT performs an emergency tracheostomy that evening. Coding:
- Correct: 31603 (Emergency tracheostomy)
- Rationale: Even though originally planned, the procedure became emergent when the patient’s condition acutely deteriorated.[1]
Example 6: Emergency Tracheostomy with Assistant Surgeon - Not Payable
Scenario: During an emergency tracheostomy, an assistant surgeon assists. The primary surgeon bills 31603, and the assistant bills 31603-80. Coding:
- Primary Surgeon: 31603
- Assistant Surgeon: 31603 - 80 (likely denied or subject to medical necessity review)
- Rationale: 31603 has assistant surgeon indicator 1, meaning payment restrictions apply. Assistant surgeon is not typically reimbursed for this code.[1]
Example 7: Incorrect Coding - Cricothyroid Membrane Approach
Scenario: Emergency tracheostomy is performed through the cricothyroid membrane. Coder reports 31603. Coding:
- Correct: 31605 (Tracheostomy, emergency procedure; cricothyroid membrane)
- Incorrect: 31603
- Rationale: 31603 is for transtracheal approach (tracheal incision); 31605 is for cricothyroid membrane approach. Review op note to determine correct code.[1][7][10]
⚠️ Important Coding Notes
Emergency vs. Planned Distinction[1][7][10]
The single most important factor in selecting 31603 is documentation of emergent, life-threatening circumstances:
| Scenario | Emergency? | Code |
|---|---|---|
| Patient in acute respiratory distress, cannot intubate | ✅ Yes | 31603 |
| Patient with stable airway, scheduled for next day | ❌ No | 31600/31601 |
| Patient scheduled for tracheostomy, deteriorates overnight requiring immediate procedure | ✅ Yes | 31603 |
| Patient with abscess and stridor but stable, added to OR schedule | ❌ No | 31600/31601 |
Location and Setting[1]
- Operating Room: Usually planned, but can be emergency
- Emergency Department: Usually emergency
- Bedside/ICU: Can be emergency or planned (in some cases)
Age Considerations[7]
- 31603 applies to patients of any age for emergency procedures
- 31601 is specifically for planned procedures on patients under 2 years
Global Period[10]
- 31603 has a 0-day global period (like most tracheostomy codes except 31610 which has 90 days)
- Post-operative visits are separately payable the day after surgery
- Document medical necessity for all post-operative visits
Documentation of Incision Site[1][7][10]
The operative note must clearly document where the incision was made:
- Transtracheal (31603): Incision into trachea, usually between 2nd and 3rd rings
- Cricothyroid membrane (31605): Incision into cricothyroid membrane
Separate Procedure Status Not Applicable[1][10]
The “separate procedure” designation applies to planned tracheostomy codes (31600-31601), not to emergency codes. Emergency tracheostomy is always a distinct, primary procedure.
