S02.611A — Fracture of Condylar Process of Right Mandible, Initial Encounter for Closed Fracture
Code Overview
S02.611A is a billable ICD-10-CM diagnosis code for fracture of the condylar process of the right mandible, initial encounter for closed fracture. It belongs to the S02.61 subcategory (Fracture of condylar process of mandible) within S02.6 (Fracture of mandible), under Chapter 19 (Injury, Poisoning and Certain Other Consequences of External Causes, S00-T88).
The 7th character “A” designates the initial encounter — meaning the patient is actively receiving evaluation and treatment for this traumatic fracture. The closed designation means there is no communicating external wound at the fracture site; the fracture is not exposed to the external environment.
Condylar process fractures of the mandible are among the most common mandibular fractures encountered in oral and maxillofacial surgery practice and emergency medicine, representing 25-35% of all mandibular fractures. The right-side specificity makes S02.611A the correct code when imaging and clinical documentation confirm the right condylar process is involved.

Clinical Description
Anatomy of the Mandibular Condylar Process
The condylar process (also called the condyle or condylar head) is the superior projection of the mandibular ramus that articulates with the glenoid fossa of the temporal bone to form the temporomandibular joint (TMJ). The condylar process consists of:
-
Condylar head — the rounded articular surface that sits within the glenoid fossa
-
Condylar neck — the narrower column of bone below the head, the most common fracture site due to its mechanical vulnerability
-
Subcondylar region — the area just below the condylar neck, above the sigmoid notch; a distinct anatomical zone with specific fracture patterns
The mandibular condyle serves critical biomechanical functions:
-
Hinge and translational movements during mastication and speech
-
Load-bearing joint (one of the most loaded joints in the body during chewing)
-
Growth center in children and adolescents — condylar fractures in pediatric patients carry distinct long-term implications for facial growth
Fracture Patterns and Classification
Condylar fractures are classified by anatomical level, displacement, and relationship between fragments:
By Anatomical Level:
-
Condylar head (intracapsular) — fracture within the TMJ capsule; involves articular surface; high risk of ankylosis, avascular necrosis, and long-term joint dysfunction
-
Condylar neck — most common; fracture at the neck between the condylar head and ramus; commonly displaced or angulated
-
Subcondylar — fracture below the condylar neck; higher on the ramus; often managed surgically due to better surgical access and mechanical stability needs
By Displacement:
-
Non-displaced — fragments in anatomical position; favorable for conservative management
-
Displaced — fragments deviated from normal alignment; may require reduction
-
Deviated — condylar head tilted medially (most common direction, pulled by the lateral pterygoid muscle)
-
Dislocated — condylar head completely out of the glenoid fossa; more severe, often requires open reduction
-
Fractured and dislocated medially — severe displacement through the medial wall of the glenoid fossa
Mechanism of Injury
Condylar process fractures most commonly result from indirect force transmission — force applied to the chin or symphysis region is transmitted along the mandible to the condylar region (the weakest structural link). Direct blows to the condylar region also occur.
Common mechanisms:
-
Falls — most common overall cause; particularly falls onto the chin (mentum)
-
Motor vehicle accidents (MVA) — direct dashboard or steering wheel impact; often bilateral condylar fractures
-
Assault — direct blows to the jaw or chin
-
Sports injuries — contact sports, cycling crashes
-
Pediatric: Falling from bicycles, playground equipment — child’s condylar fractures are biomechanically distinct due to growth cartilage involvement
Clinical Signs and Symptoms
Examination findings in right condylar fracture:
-
Malocclusion — the most important clinical sign; premature posterior occlusal contact on the right (ipsilateral to fracture) with open bite on the left; deviation of the mandible to the right on opening
-
Deviation on mouth opening — the mandible deviates toward the fractured (right) side on opening due to loss of normal condylar translation
-
Preauricular pain and swelling — right preauricular tenderness, swelling, and hematoma
-
Limited mouth opening (trismus) — pain-limited opening; may be due to muscle spasm, hematoma, or mechanical block
-
Hemarthrosis of the right TMJ — blood within the joint capsule causing swelling and pain
-
Ear pain or fullness — due to proximity of the condyle to the external auditory meatus; blood may track into the ear canal
-
Chin laceration — suggests indirect mechanism (fall on chin → force transmitted to condyle); look for concomitant contralateral condylar fracture or parasymphyseal fracture
-
Facial nerve proximity — the facial nerve passes near the condylar region; rarely injured in closed condylar fractures but at risk during surgical approaches
Diagnosis
-
Panoramic radiograph (panorex/OPG) — first-line imaging; excellent overview of the entire mandible; may miss highly comminuted or medially displaced condylar head fractures
-
CT maxillofacial with 3D reconstruction — gold standard for surgical planning; defines fracture level, angulation, displacement, and dislocation accurately
-
CBCT (cone beam CT) — used in oral surgery offices for high-resolution mandibular imaging
-
Plain films (PA mandible, Towne’s view) — adjunct; less detailed than CT
Treatment Options
Treatment is dictated by fracture level, degree of displacement, dislocation, patient age, occlusal status, and associated injuries:
Conservative (closed) management:
-
Soft diet and function (for non-displaced or minimally displaced fractures)
-
Maxillomandibular fixation (MMF) — wiring the teeth together (arch bars or IMF screws) to allow functional loading of the fracture; typically 2-4 weeks
-
Early mobilization protocols — physiotherapy to prevent TMJ stiffness and ankylosis
Open (surgical) management:
-
Indicated for: significant displacement, dislocation, open bite deformity, bilateral fractures causing functional compromise, foreign body in joint, pediatric patients in select situations
-
Open reduction and internal fixation (ORIF) — via retromandibular, preauricular, or transparotid approach; titanium miniplates and screws
-
Endoscopic-assisted ORIF — minimally invasive approach through intraoral or small external incisions; growing in adoption
-
Arthroplasty/condylectomy — for severely comminuted intracapsular fractures or ankylosis cases
7th Character Table
| 7th Char | Full Code | Description | When to Use |
|---|---|---|---|
| A | S02.611A | Initial encounter — closed fracture | Active treatment; ED visit, admission, surgery, any provider during active care |
| B | S02.611B | Initial encounter — open fracture | Fracture with external communicating wound (e.g., intraoral laceration over fracture site) |
| D | S02.611D | Subsequent encounter — routine healing | Follow-up during normal fracture healing |
| G | S02.611G | Subsequent encounter — delayed healing | Healing slower than expected |
| K | S02.611K | Subsequent encounter — nonunion | Fracture fails to unite |
| S | S02.611S | Sequela | Late effects (e.g., chronic TMJ dysfunction, ankylosis, malocclusion) |
Note
Open vs. closed — condylar fracture nuance: An intraoral laceration overlying the mandibular fracture line makes it an open fracture (code S02.611B). This is clinically important because open mandibular fractures carry a significantly higher infection risk (exposed to oral flora) and require antibiotic prophylaxis and often more aggressive surgical management.

Tip
S02.611 vs S02.621 — condylar vs subcondylar: These are anatomically distinct and separately coded in ICD-10-CM. The condylar process (S02.611) refers to the condylar head and neck; the subcondylar process (S02.621) refers to the region just below the condylar neck. When imaging identifies the fracture specifically as subcondylar, code S02.621A (right) instead.
Includes / Excludes Notes

Pathological fractures of the mandible not addressed here — see M84.58-
Excludes2 (S02 Category — May Code Additionally If Present)
These conditions are not included in S02 but may exist simultaneously with S02.611A and be coded additionally:
| Code | Description | Coding Note |
|---|---|---|
| S03.0- | Dislocation of jaw | If TMJ dislocation coexists with or results from the condylar fracture |
| S04.5- | Injury of facial nerve | If CN VII injury is documented from the fracture or surgical approach |

| S00.8- | Superficial injury of head | Chin laceration, abrasion |
| S01.8- | Open wound of head | If an open wound is also present |
Code Also (Mandatory — S02 Category Level)
Code also any associated intracranial injury (S06.-)
This instruction applies even when the intracranial injury appears clinically minor. Common pairings with condylar fractures:
| Code | Description |
|---|---|
| S06.0X0A | Concussion without LOC, initial encounter |
| S06.0X1A | Concussion with LOC 30 min or less, initial encounter |
| S06.0X2A | Concussion with LOC 31-59 min, initial encounter |
External Cause Codes Required
| External Cause Code | Description |
|---|---|
| W01.110A | Fall on same level, striking face/jaw, initial encounter |
| W17.89XA | Other fall from one level to another, initial encounter |
| W50.0XXA | Accidental hit/strike by another person (assault), initial |
| V49.50XA | Driver injured in collision with unspecified vehicle, initial |
| X58.XXXA | Exposure to other specified factors, initial encounter |
| Y93.89 | Activity, other specified (sports) |
| Y99.8 | Other external cause status |
HCC (Hierarchical Condition Category) Mapping
S02.611A does NOT map to a CMS-HCC in any current risk adjustment model.
| HCC Model | HCC Assignment | RAF Impact |
|---|---|---|
| CMS-HCC Model V28 | Not assigned | No RAF |
| RxHCC Model | Not assigned | No RAF |
| HHS-HCC (ACA Marketplace) | Not assigned | No RAF |
Sequela HCC consideration: While the acute fracture code carries no RAF, long-term sequelae of condylar fractures — such as temporomandibular joint dysfunction, chronic pain, ankylosis, or facial asymmetry requiring ongoing care — should be coded using condition-specific sequela codes (S02.611S + M26.60- for TMJ disorder, or M26.64 for arthritis of TMJ) when they drive ongoing management. These also do not typically map to HCC but complete the clinical picture for quality review.
MS-DRG Mapping (Inpatient)
S02.611A as a principal diagnosis typically groups to the craniofacial/head trauma or other head injury DRG families. Mandibular fractures requiring surgical repair are among the more common maxillofacial trauma admissions.
| MS-DRG | Description | Trigger |
|---|---|---|
| 163 | Major Head Trauma with MCC | S02.611A as PDx + MCC present |
| 164 | Major Head Trauma with CC | S02.611A as PDx + CC present |
| 165 | Major Head Trauma without CC/MCC | S02.611A as PDx, no CC/MCC |
If surgical procedure (ORIF) is performed during the admission:
Mandibular ORIF (CPT 21465) maps to ICD-10-PCS in the inpatient setting. The surgical DRG triggered depends on the principal diagnosis and operating room procedure:
| MS-DRG | Description | Trigger |
|---|---|---|
| 130 | Cranial/Facial Procedures with CC | Facial fracture ORIF + CC |
| 131 | Cranial/Facial Procedures without CC/MCC | Facial fracture ORIF, no CC/MCC |
MDC: MDC 01 — Diseases and Disorders of the Nervous System (for head trauma grouping) or MDC 03 — Ear, Nose, Mouth, and Throat (for isolated mandible surgical repair)
CC/MCC Status:
-
S02.611A functions as a CC when appearing as a secondary diagnosis in certain DRG contexts
-
Will contribute to DRG severity upgrade from base DRG when present as a secondary dx with a qualifying principal diagnosis

Example 1 — Closed Condylar Fracture, Conservative Management
Clinical Scenario:
A 28-year-old male presents to the ED after falling off his bicycle and striking his chin on the pavement. He has right preauricular swelling, tenderness, limited mouth opening, and deviation to the right on opening. Panorex and CT maxillofacial reveal a non-displaced fracture of the right mandibular condylar neck. No LOC. Treatment plan: soft diet, NSAIDs, early mobilization, and close follow-up with oral surgery.

Assistant surgeon: Yes — modifier -80 applicable for 21465.
Example 3 — Bilateral Condylar Fractures from MVA
Clinical Scenario:
A 42-year-old male is involved in a head-on MVA, striking the steering wheel. He presents with bilateral preauricular pain, anterior open bite, and bilateral limited mouth opening. CT shows displaced right condylar neck fracture and minimally displaced left condylar neck fracture. He undergoes right-side ORIF (21465-RT) and left-side closed treatment with MMF (21453-LT).
ICD-10-CM:
-
S02.611A— Fracture of condylar process of right mandible, initial encounter, closed -
S02.612A— Fracture of condylar process of left mandible, initial encounter, closed -
S06.0X1A— Concussion with LOC 30 min or less, initial encounter -
V49.50XA— Driver injured in collision, unspecified vehicle, traffic, initial encounter

-
21465-RT— Open treatment of mandibular condylar fracture, right -
21453-LT— Closed treatment of mandibular fracture with interdental fixation, left -
70486— CT maxillofacial
Bilateral fracture billing note: When both sides undergo different procedures, report each CPT with the appropriate laterality modifier (RT/LT). Do not use modifier -50 when different procedures are performed on each side.
Example 4 — Condylar Fracture with TMJ Dislocation (Fracture-Dislocation)
Clinical Scenario:
A 52-year-old male falls from a ladder, landing on his chin. CT reveals a right condylar head fracture with complete dislocation of the condylar head out of the glenoid fossa (medial dislocation). He is taken to the OR for open reduction of the condylar fracture-dislocation.
ICD-10-CM:
-
S02.611A— Fracture of condylar process of right mandible, initial encounter, closed -
S03.01XA— Dislocation of jaw, right side, initial encounter (fracture-dislocation — code both) -
W17.89XA— Other fall from one level to another, initial encounter
CPT:
21465— Open treatment of mandibular condylar fracture (includes reduction of dislocation when performed as part of fracture ORIF)
Example 5 — Pediatric Condylar Fracture, Conservative Management
Clinical Scenario:
An 8-year-old boy falls from playground equipment, striking his chin. He has right preauricular tenderness with deviation to the right on opening. CT reveals a greenstick/incomplete fracture of the right condylar head (intracapsular). No LOC. Pediatric OMFS recommends soft diet and functional therapy — no MMF due to age and incomplete fracture type.
ICD-10-CM:
-
S02.611A— Fracture of condylar process of right mandible, initial encounter, closed -
W09.8XXA— Fall from other playground equipment, initial encounter -
Y93.89— Activity, other specified
CPT:
-
21450— Closed treatment of mandibular fracture without manipulation -
70486— CT maxillofacial without contrast
Pediatric coding note: Pediatric condylar fractures have a higher remodeling potential than adult fractures. The growth center involvement should be documented in the provider’s note to support the conservative management decision and any future claims for follow-up care.
Example 6 — Encounter Type Progression (A → D → S)
Same patient as Example 2:
-
Admission and surgery (active treatment):
S02.611A— initial encounter for closed fracture -
4-week post-op office visit (hardware check, occlusion assessment, healing on track):
S02.611D— subsequent encounter for fracture with routine healing -
18 months later (residual right TMJ pain and limited opening persisting after healed fracture):
S02.611S+M26.621— arthralgia of right temporomandibular joint as sequela
Key Coding Pitfalls & Tips
-
S02.611 vs S02.621 — condylar vs subcondylar: These are distinct codes. S02.611A is for the condylar process (including condylar head and condylar neck). S02.621A is for the subcondylar process (the zone below the condylar neck on the upper ramus). Verify the exact fracture location on imaging and in the clinical note before coding.
-
Open vs. closed (intraoral laceration = open fracture): Any intraoral laceration that communicates with the fracture makes it an open fracture — code S02.611B (initial encounter, open). Open mandibular fractures are contaminated with oral flora and require different management. This distinction is critical for DRG severity and clinical documentation.
-
Always apply the “Code also” S06.- instruction. Even if the intracranial injury appears clinically minimal (brief LOC, concussion), it must be coded when documented per the mandatory instructional note.
-
Right vs left laterality — always verify imaging. Condylar fractures can be unilateral or bilateral. Verify laterality with the imaging report and clinical note; do not assume.
-
Bilateral fractures = two separate codes. Code S02.611A (right) and S02.612A (left) separately when bilateral condylar fractures are documented. There is no single bilateral condylar fracture code.
-
External cause codes are expected for all Chapter 19 injuries. Mechanism (V/W/X/Y), place, and activity codes complete the claim and support medical necessity and epidemiological tracking.
-
Global period for 21465 = 90 days. Any subsequent procedures or office visits for unrelated conditions during the 90-day global period require appropriate modifier management.
-
Sequela coding for TMJ dysfunction: Long-term post-fracture TMJ dysfunction, ankylosis, or malocclusion should be coded in the sequela phase using S02.611S plus the specific condition code (M26.6- for TMJ disorders, M26.20 for dental arch length discrepancy). These are important for ongoing specialist visits.
