What Does CPT Code 00160 Mean?CPT code 00160 describes anesthesia services provided for procedures on the nose — limited. This code covers nasal procedures that do not involve the paranasal sinuses — distinguishing it from sinus surgery (00162 for radical, 00164 for endoscopic). Common procedures include closed reduction of nasal fracture, septoplasty, rhinoplasty (cosmetic or functional), nasal biopsy, and turbinate reduction. This is one of the most frequently used nose anesthesia codes in the 00100-00222 range.Key Code Attributes:

• Billable Status: Fully billable as a standalone anesthesia service
• Base Units (CMS 2026): 5
• Primary Setting: Ambulatory surgery center or hospital outpatient department
• Provider Type: Anesthesiologist (MD/DO), CRNA with physician supervision, or anesthesia assistant under physician direction
• Service Category: General anesthesia (most common) or MAC
• Effective Status: Active CPT code with no planned retirement (verified through 2026)
• Common Surgical Partners: ENT (otolaryngology), facial plastic surgery, plastic surgery---

What Services and Procedures Does CPT Code 00160 Cover?

CPT 00160 covers anesthesia for surgical procedures confined to the nasal cavity and external nose, excluding the paranasal sinuses. These procedures range from brief fracture reductions to more complex septorhinoplasty cases. Covered Procedures:- Closed reduction of nasal bone fracture- Septoplasty for nasal airway obstruction- Rhinoplasty (cosmetic — external or closed approach)- Rhinoplasty (functional — nasal valve repair, tip rhinoplasty)- Nasal biopsy (excisional or incisional)- Removal of nasal foreign body under general anesthesia- Nasal packing or cautery for epistaxis under anesthesia- Turbinate reduction (submucous resection, radiofrequency)- Excision of nasal lesion (external approach, not involving sinuses)- Nasal synechiae lysis | ## Exclusions| Excluded | Correct Code | Rationale | | ----------|-------------|----------- | | FESS or sinus surgery | 00162 or 00164 | Sinus involvement requires broader code | | Septoplasty with FESS | 00164 | Combined nasal and sinus procedure | | Rhinectomy or total nasal reconstruction | 00162 | Radical nasal procedure | | Nasal biopsy (minor, office-based) | Not billable | No anesthesia provider involvement | | Integumentary nasal skin procedures | 00100 | Skin-only procedures (e. |

g., skin cancer excision on nose) |---

When Is CPT Code 00160 the Right Code to Use?

Step-by-Step Code Selection1. Confirm the surgical site is limited to the nose without sinus involvement2. If the procedure involves the paranasal sinuses (FESS, ethmoidectomy, sinusotomy), use 001643. If the procedure is radical (rhinectomy, total nasal reconstruction), use 001624. If the procedure is a diagnostic nasal biopsy only, use 001645. If the procedure is on the skin of the nose without entering the nasal cavity, use 001006. Select appropriate modifiers for provider type and ASA physical status

Documentation Requirements

Preoperative DocumentationComprehensive history and physical including airway assessment (nasal obstruction may affect mask ventilation and intubation), bleeding risk assessment (nasal surgery can involve significant blood loss), ASA classification, anesthesia plan specifying general anesthesia versus MAC, NPO status, and review of any anticoagulant or antiplatelet medications.

Intraoperative DocumentationAnesthesia start and stop times, vital signs recorded at minimum 5-minute intervals, all anesthetic agents and doses, airway management technique (endotracheal tube, laryngeal mask airway, or mask), use of throat pack (document placement AND removal), blood loss estimation, fluid administration, and any use of hypotensive anesthesia to reduce bleeding.

Postoperative DocumentationPACU admission and discharge times, pain scores, PONV assessment and treatment (nasal surgery has higher PONV risk due to blood swallowing), Aldrete score, and any airway concerns related to nasal packing or edema.

ReimbursementNote: Anesthesia services use a unit-based formula, not RVUs. Medicare payment = (Base Units + Time Units + Modifying Units) x Anesthesia Conversion Factor. The 2026 Medicare anesthesia CF is approximately $21.

71 (varies by locality). Commercial payer CFs are typically 2-5x higher. | ## Common Modifiers| Modifier | Use Case | | ----------|---------- | | AA | Anesthesiologist personally performs service | | QS | Monitored anesthesia care (MAC) | | QK | Medical direction of 2-4 concurrent cases | | QX | CRNA with medical direction | | QZ | CRNA without medical direction | | P1-P4 | ASA physical status | | 23 | Unusual anesthesia — may apply for complex airway management |

Payer Considerations- Medicare covers CPT 00160 when the underlying surgical procedure is medically necessary (e.

g., septoplasty for nasal airway obstruction, fracture reduction for trauma)- Cosmetic rhinoplasty is not covered by Medicare or most commercial payers — anesthesia must be collected from the patient directly- Some commercial payers require prior authorization for septoplasty and functional rhinoplasty — verify coverage before scheduling- Functional nasal surgery (septoplasty, turbinate reduction, nasal valve repair) is typically covered when documented for airway obstruction- Bundled payment arrangements in some ASCs may include anesthesia in the facility fee — verify whether anesthesia is separately billable- NCCI edits do not bundle CPT 00160 with nasal surgical codes — anesthesia is always separately reportable---

Coding Errors to Avoid1.

Using 00160 for FESS or sinus surgery — When the sinuses are involved, use 00164 (4 base units)2. Using 00160 for radical nasal surgery — Rhinectomy or total nasal reconstruction requires 001623. Billing 00160 for integumentary nasal skin procedures — Skin-only excisions on the nose use 001004. Missing throat pack documentation — Document placement AND removal of throat pack to avoid patient safety and compliance issues5. Billing bilateral procedures separately — Single anesthesia code per session regardless of unilateral or bilateral nasal surgery6. Coding cosmetic rhinoplasty as medical — Verify payer policy for functional versus cosmetic components---

Real-World Scenario

Scenario 1: Septoplasty With Turbinate ReductionA 28-year-old male with nasal airway obstruction due to deviated septum and hypertrophic turbinates undergoes septoplasty with submucous resection of inferior turbinates under general anesthesia via endotracheal tube. A throat pack is placed and removed. Total anesthesia time is 45 minutes. Patient is ASA I.

Coding: CPT 00160 + AA + P1. Base 3, time 3 (45 min), total 6 units. Estimated payment at $21.71/unit: ~$130.26.

Scenario 2: Closed Reduction of Nasal FractureA 22-year-old male presents with a displaced nasal bone fracture following a sports injury. He undergoes closed reduction under general anesthesia via laryngeal mask airway. Total anesthesia time is 20 minutes. Patient is ASA I.

Coding: CPT 00160 + AA + P1. Base 3, time 1 (20 min rounds to 1), total 4 units. Estimated payment: ~$86.84.---

Frequently Asked Questions

What Is the Difference Between CPT 00160 and CPT 00164?

CPT 00160 is for nasal procedures limited to the nose (septoplasty, rhinoplasty, turbinate reduction, fracture reduction). CPT 00164 is for procedures involving the nose and paranasal sinuses (FESS, ethmoidectomy, sinusotomy). CPT 00164 has higher base units (4 vs. 3).

Is CPT 00160 Covered for Cosmetic Rhinoplasty?

CPT 00160 may be coded for cosmetic rhinoplasty, but Medicare and most commercial payers do not cover anesthesia for purely cosmetic procedures. Anesthesia charges must be collected directly from the patient. For combined functional and cosmetic rhinoplasty, document the functional component carefully.

What Airway Management Is Typical for Nasal Surgery?

General anesthesia with an endotracheal tube is standard for nasal surgery to protect the airway from blood and debris. A laryngeal mask airway may be used for brief procedures such as nasal fracture reduction. The surgeon may also place a throat pack to absorb blood.

Does CPT 00160 Cover Nasal Packing for Epistaxis?

Yes, when epistaxis requiring nasal packing or cautery is performed under general anesthesia or MAC with an anesthesia provider, CPT 00160 is appropriate. Simple office-based nasal packing without anesthesia provider involvement is not billable.

Can CPT 00160 Be Billed With 00164 in the Same Session?

No. Only one anesthesia code is reported per anesthetic session. If the procedure involves both nasal and sinus structures, use 00164 for the entire case.

What Is the Typical Conversion Factor for CPT 00160?Medicare CF is approximately $21.

71 for 2026. Commercial payer CFs range from $40 to $100 depending on the payer and geographic region. At 6 total units, a commercial payer paying $60/unit would yield $360.---

Key Takeaways- CPT 00160 is for nasal procedures without sinus involvement- Base units 3 — lower than sinus codes (4)- Distinguish from CPT 00164 when sinuses are involved- Not for integumentary-only nasal skin procedures (use 00100)- Single code per anesthetic session- Document throat pack placement and removal- Cosmetic rhinoplasty anesthesia is typically patient-pay
