What Does CPT Code 00102 Mean?

CPT code 00102 describes anesthesia services provided for procedures involving plastic repair of cleft lip. This congenital condition involves a split or opening in the upper lip that occurs when facial structures fail to fuse during embryonic development. Anesthesia for cleft lip repair requires specialized knowledge of pediatric airway anatomy, the potential for difficult mask ventilation, and the physiologic changes associated with congenital anomalies.

Cleft lip repair (cheiloplasty) is typically performed between 3 and 6 months of age, though timing may vary based on the child’s overall health, weight, and the presence of associated syndromes. The anesthesia provider must be prepared for the unique challenges of managing the airway in infants with craniofacial differences, including potential difficulty with mask seal, laryngoscopy, and intubation.

Key Code Attributes:

• Billable Status: Fully billable as a standalone anesthesia service
• Base Units (CMS 2026): 6
• Primary Setting: Hospital inpatient or outpatient surgical department, pediatric specialty hospital
• Provider Type: Anesthesiologist (MD/DO) with pediatric expertise, CRNA under physician supervision, or anesthesia assistant under physician direction
• Service Category: General anesthesia (cleft lip repair almost always requires general anesthesia)
• Effective Status: Active CPT code with no planned retirement (verified through 2026)
• Typical Patient Population: Infants (typically 3-6 months), though older children and adults with unrepaired or revision cleft lip may also require this code

What Services and Procedures Does CPT Code 00102 Cover?

CPT 00102 covers anesthesia for surgical procedures involving plastic repair of cleft lip. The code is specific to cleft lip and does not include cleft palate repair, which has its own code (00172).

Covered Procedures and Surgical Indications:

• Primary unilateral cleft lip repair (cheiloplasty) — typically performed at 3-6 months of age
• Primary bilateral cleft lip repair — more complex than unilateral, often requires staged approach
• Revision cleft lip repair for residual deformity, scar revision, or functional improvement
• Cleft lip repair associated with cleft lip and palate (CLP) — when both conditions are repaired in staged procedures
• Repair of cleft lip with associated nasal deformity (primary rhinoplasty at time of lip repair)
• Secondary cleft lip reconstruction following prior repair

What Does CPT 00102 Specifically Exclude?

CPT 00102 does not cover anesthesia for:

• Cleft palate repair alone (use CPT 00172)
• Procedures on the external, middle, or inner ear (use codes 00120-00126)
• Nasal surgery not associated with cleft lip repair (use codes 00160-00164)
• Intraoral procedures not involving cleft lip (use codes 00170-00176)
• Craniofacial procedures involving bone work or intracranial access (use codes 00210-00222)
• Simple lacerations closed under local anesthesia only
• Dental procedures under general anesthesia (use 00170 for intraoral dental surgery)

When Is CPT Code 00102 the Right Code to Use?

Code selection for anesthesia services follows a systematic approach based on the specific surgical procedure. Use CPT 00102 when the surgical procedure is specifically a plastic repair of cleft lip.

Step-by-Step Code Selection:

1. Confirm the diagnosis is cleft lip (unilateral or bilateral) — verify the surgical plan specifically addresses the lip
2. Distinguish cleft lip from cleft palate — lip repair uses 00102, palate repair uses 00172, simultaneous repair uses the code for the more complex procedure
3. Verify the patient’s age — infants require specialized pediatric anesthesia equipment and dosing
4. Check for associated congenital anomalies — cleft lip may be associated with syndromes (e.g., Pierre Robin sequence, Van der Woude syndrome, 22q11.2 deletion) that affect airway management
5. Apply extreme age qualifying circumstance code 99100 if patient is younger than 1 year (most cleft lip patients qualify)

How Does CPT 00102 Differ From Related Anesthesia Codes?

| Code | Anatomic Area | Typical Surgical Examples | Base Units | |---

---|---------------|--------------------------|------------| | 00102 | Cleft lip | Primary cheiloplasty, revision cleft lip repair | 6 | | 00172 | Cleft palate | Palatoplasty, cleft palate repair | 6 | | 00170 | Intraoral (general) | Dental extractions, oral biopsy | 5 | | 00176 | Radical intraoral | Mandibular resection, radical oral tumor excision | 7 | | 00326 | Larynx/trachea (<1 yr) | Laryngeal surgery in infants | 7 |

What Documentation Is Required to Support CPT 00102?

Anesthesia documentation for CPT 00102 must follow CMS and ASA guidelines, with special attention to the unique aspects of pediatric and cleft lip anesthesia.

What Must the Provider Document?

Preoperative Documentation:

• Comprehensive patient history and physical examination
• ASA Physical Status Classification (ASA I through VI)
• Airway assessment — Mallampati score, neck mobility, mouth opening, presence of craniofacial anomalies
• Anesthesia plan with rationale for general anesthesia
• Informed consent for anesthesia, including discussion of pediatric-specific risks
• Assessment of aspiration risk and feeding management plan
• Evaluation for associated congenital anomalies or syndromes
• Birth history, weight, and growth parameters for infants Intraoperative Documentation:
• Anesthesia start and stop times (continuous face-to-face care)
• Vital signs at minimum 5-minute intervals
• Type, dose, route, and time of all anesthetic agents
• Fluid administration and estimated blood loss
• Use of neuromuscular blockade and reversal agents
• Airway management technique (endotracheal intubation, LMA)
• Depth of anesthesia monitoring
• Temperature management (infants are at high risk for hypothermia)
• Any complications or adverse events Postoperative Documentation:
• PACU admission and discharge times
• Pain scores using age-appropriate pain scales (FLACC, CHEOPS)
• Analgesic administration
• Assessment of postoperative nausea and vomiting
• Airway patency and respiratory status
• Aldrete score or equivalent recovery assessment
• Handoff communication to PACU staff and parents

Base Unit Assignment and Time Calculation

Component	Value
Base Units (CMS 2026)	6
Time Unit Increment	15 minutes
Physical Status Modifier P3	+1 unit
Physical Status Modifier P4	+2 units
Physical Status Modifier P5	+3 units
Qualifying Circumstance 99100 (<1 year)	+1 unit

How Does CPT 00102 Affect Medical Billing and Reimbursement?

Reimbursement for anesthesia services follows the formula: (Base Units + Time Units + Physical Status Units + Qualifying Circumstance Units) x Anesthesia Conversion Factor. 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.

Payer Considerations

Medicare:

• Anesthesia services are paid under the Medicare Physician Fee Schedule using the anesthesia-specific payment formula
• Base units for CPT 00102 are established by CMS at 6 base units for 2026
• Medicare pays separately for anesthesia services; the surgical code is billed separately by the surgeon
• Medical direction rules apply (CRNA supervision — QK, QX, QY modifiers) Commercial Payers:
• Many follow Medicare payment methodology but with higher conversion factors
• Cleft lip repair is a covered reconstructive procedure for most commercial plans
• Prior authorization is rarely required for cleft lip repair (medically necessary reconstructive surgery)
• Payer-specific modifiers may be required for multiple procedures or staged repairs

What Modifiers Are Commonly Used With CPT 00102?

Modifier	Description	When to Use
AA	Anesthesia services performed personally by anesthesiologist	Physician personally performs entire anesthesia service
QK	Medical direction of two to four concurrent anesthesia procedures	Supervising CRNA or AA for up to 4 concurrent cases
QX	CRNA service with medical direction by a physician	CRNA provides anesthesia under physician direction
QY	Medical direction by anesthesiologist of one CRNA	One CRNA directed by anesthesiologist
QZ	CRNA service without medical direction by a physician	Independent CRNA practice
P1-P6	Physical status modifiers	P1 = normal healthy, P2 = mild systemic disease, etc.
99100	Extreme age (<1 year or >70 years)	Most cleft lip patients qualify

Are There Any Prior Authorization or LCD Requirements?

Cleft lip repair is reconstructive surgery and is generally considered medically necessary. Medicare and most commercial payers cover anesthesia for cleft lip repair without prior authorization. However:

• Verify coverage for any associated procedures performed during the same anesthetic session
• Document medical necessity for each component of the anesthetic care
• Some payers may require pre-certification for inpatient admissions

What CPT or HCPCS Codes Are Commonly Billed Alongside CPT 00102?

Code Type	Code Range	Description	Relationship
Surgical	40700-40720	Plastic repair of cleft lip	Primary surgical code for unilateral/bilateral repair
Surgical	40761	Plastic repair of cleft lip with cross-lip pedicle flap	Complex cleft lip repair
Surgical	30460-30462	Rhinoplasty for nasal deformity	Associated nasal repair during cleft lip surgery
Qualifying	99100	Extreme age (<1 year)	Most cleft lip patients qualify
Qualifying	99140	Emergency conditions	Rare in planned cleft lip repair

What Coding Errors Should You Avoid With CPT 00102?

Top 5 Coding Errors Ranked by Audit Frequency

1. Confusing CPT 00102 (Cleft Lip) with CPT 00172 (Cleft Palate) The most common error is using 00102 for palate repair or vice versa. Cleft lip (cheiloplasty) uses 00102; cleft palate (palatoplasty) uses 00172. When both are repaired during the same surgical session, report the code for the more complex procedure or sequence according to payer guidance.
2. Failing to Report Qualifying Circumstance 99100 for Age Most cleft lip repairs occur in infants younger than 1 year. Qualifying circumstance code 99100 adds 1 base unit. Failure to report this code results in underpayment. However, do not report 99100 with codes that already include age in their description (e.g., 00326).
3. Incorrect Physical Status Modifier Assignment Infants with cleft lip may have associated syndromes that affect ASA classification. Document specific clinical findings supporting the physical status designation. An infant with isolated cleft lip and no other anomalies is typically ASA I or II.
4. Bundling Anesthesia and Surgical Services Together Anesthesia is always a separately reportable service from the surgical procedure. CPT 00102 must be billed on a separate claim line with appropriate anesthesia modifiers.
5. Using CPT 00102 for Non-Cleft Lip Procedures Some billers incorrectly use 00102 for other pediatric plastic surgery procedures on the face. The code is specific to cleft lip. Use 00100 for integumentary procedures on the face, or 00170 for intraoral procedures.

How Does CPT 00102 Relate to Other Anesthesia Codes?

Anesthesia Code Relationships for Craniofacial Procedures

CPT Code	Anatomic Extent	Complexity Level	Base Units (2026)
00102	Cleft lip	Moderate	6
00172	Cleft palate	Moderate	6
00100	Integumentary — head and neck	Low-Moderate	5
00170	Intraoral	Moderate	5
00176	Radical intraoral	High	7
00326	Larynx/trachea (<1 yr)	High	7

Code Sequencing and Reporting Rules

• Report one anesthesia code per surgical session
• For combined cleft lip and palate repair, report the code for the more complex procedure
• Qualifying circumstance codes (99100, 99116, 99135, 99140) may be reported in addition to the primary anesthesia code
• Do not report 99100 with codes that have age-specific descriptors (e.g., 00326, 00561, 00834, 00836)

Real-World Coding Scenario — How CPT 00102 Is Applied in Practice

A 4-month-old infant (weight 6.2 kg) with unilateral complete cleft lip undergoes primary cheiloplasty. The patient has no other congenital anomalies and is developing normally. Anesthesia induction is performed with sevoflurane in oxygen, intravenous access is obtained after induction, and the trachea is intubated with a cuffed endotracheal tube. Maintenance anesthesia includes sevoflurane and fentanyl. The anesthesia record documents: preoperative assessment with ASA II (infant with congenital anomaly), induction at 0800, emergence at 0915, total anesthesia time 75 minutes. The case proceeds without complications, and the infant is extubated awake and transported to the PACU.

Correct Code Application

CPT 00102 — Anesthesia for procedures involving plastic repair of cleft lip

• Modifiers: AA (anesthesiologist personally performed) + P1 (normal healthy patient)
• Base Units: 6
• Time Units: 75 minutes divided by 15 = 5 time units
• Qualifying Circumstance: 99100 (extreme age, patient younger than 1 year) = +1 unit
• Total Units: 6 + 5 + 1 = 12 units
• Conversion Factor: Based on applicable payer rate

Common Mistake in This Scenario

An inexperienced coder might report CPT 00172 (cleft palate repair) because the patient has a cleft lip and the coder confuses the two codes. Alternatively, they might fail to append modifier 99100 for extreme age, resulting in the loss of one base unit of reimbursement. The correct approach requires careful attention to both the specific procedure code and the qualifying circumstance modifier.

Frequently Asked Questions About CPT Code 00102

Is CPT 00102 specific to cleft lip only?

Yes. CPT 00102 is specific to anesthesia for plastic repair of cleft lip. Cleft palate repair uses CPT 00172. Do not use 00102 for other types of lip surgery or for other pediatric plastic surgery procedures.

What qualifying circumstance codes apply to CPT 00102?

Code 99100 (extreme age, younger than 1 year or older than 70 years) most commonly applies, since cleft lip repair is typically performed in infants 3-6 months old. Code 99140 (emergency conditions) may apply in rare cases. Code 99116 (controlled hypothermia) does not typically apply.

Can CPT 00102 be used for bilateral cleft lip repair?

Yes. CPT 00102 covers both unilateral and bilateral cleft lip repair. The code does not differentiate by extent of the cleft. If bilateral repair is more complex and time-consuming, the additional work is captured through time units and physical status modifiers, not a different anesthesia code.

What is the difference between CPT 00102 for cleft lip and CPT 00172 for cleft palate?

The key difference is anatomic: 00102 applies to the lip (anterior oral cavity/face), while 00172 applies to the palate (roof of the mouth, posterior oral cavity). Both are congenital repair codes but address different structures. When both are repaired simultaneously, report the code for the primary procedure.

What is the typical anesthesia technique for cleft lip repair?

Cleft lip repair is performed under general anesthesia with endotracheal intubation. The endotracheal tube is typically secured in the midline of the lower lip or taped to the chin at the midline, allowing the surgeon access to the upper lip and nose. Anesthesia maintenance typically includes volatile agents with opioid analgesia. Caudal or ilioinguinal nerve blocks are not applicable for this procedure.

Do cleft lip patients require special airway considerations?

Yes. Infants with cleft lip may have associated craniofacial anomalies that make mask ventilation and intubation challenging. The anesthesia provider must have pediatric difficult airway equipment available, including multiple laryngoscope blade sizes, supraglottic airway devices, and a plan for difficult airway management.

What is the typical length of stay after cleft lip repair?

Cleft lip repair for otherwise healthy infants is typically performed as an inpatient procedure with a 23-hour observation stay or short inpatient admission. Some centers perform the surgery as an outpatient procedure with discharge on the same day.
