Crystal's MCW Coder HubQ67.4 — Other Congenital Deformities of Skull, Face and Jaw
Code Overview
Q67.4 is a billable ICD-10-CM diagnosis code for other congenital deformities of skull, face and jaw. It belongs to the Q67 category — Congenital musculoskeletal deformities of head, face, spine and chest — within Chapter 17 (Congenital Malformations, Deformations and Chromosomal Abnormalities, Q00-Q99).
Q67.4 is a NEC (not elsewhere classified) residual code that captures congenital deformities of the skull, face, and jaw that do not have a more specific code within the Q67 category or elsewhere in Chapter 17. It encompasses a broad range of congenital structural abnormalities that are present at birth (or at least have their origin in prenatal development), affect the bony and soft tissue architecture of the craniofacial region, and cannot be attributed to an acquired etiology.
This code is POA (present on admission) exempt — all congenital condition codes are inherently present on admission and are excluded from POA indicator requirements.

Clinical Description
What Q67.4 Captures
Q67.4 is an inclusive, residual NEC code that explicitly includes four distinct congenital conditions in the ICD-10-CM Tabular List, while also serving as the default code for any other congenital deformity of the skull, face, and jaw not specifically indexed elsewhere:
Explicitly Included Conditions:
1. Congenital Depressions in Skull
A localized indentation or concavity in the calvarium (skull vault) present from birth. These may result from:
-
In utero pressure deformities — fetal head pressing against the maternal bony pelvis (ischial spines, sacral promontory) during prolonged labor or in fixed fetal positions (particularly with oligohydramnios)
-
Intrauterine constraint — fibroids, uterine septum, or reduced amniotic fluid limiting normal skull development
-
Instrumented delivery — forceps delivery producing localized cranial depression (though this would typically be coded as a birth injury — P13.-)
-
Lückenschädel — a developmental congenital lacunar skull with focal areas of skull thinning/depression associated with neural tube defects; though more specifically associated with neural tube defects (Q01.- or Q05.-) when that etiology is identified
-
Isolated, small congenital skull depressions without neural tube association or birth injury documentation are captured at Q67.4
2. Congenital Hemifacial Atrophy or Hypertrophy
An asymmetry of the face due to undergrowth (atrophy) or overgrowth (hypertrophy) of one side of the face beginning in utero or early development:
-
Congenital hemifacial atrophy (Romberg disease / Progressive hemifacial atrophy): A condition of uncertain but likely congenital/neurodevelopmental origin involving unilateral wasting of the skin, subcutaneous tissue, muscle, cartilage, and bone of one side of the face. The atrophy may involve all tissue planes on the affected side, causing progressive facial asymmetry. Often associated with neurological findings (seizures, trigeminal neuralgia, contralateral focal neurological signs). Coded Q67.4 when documented as congenital or developmental in origin.
-
Congenital hemifacial hypertrophy: Overgrowth of all or some of the tissues on one side of the face, including the maxilla, mandible, teeth, tongue, and skin. May be isolated or associated with syndromes (hemihyperplasia, Beckwith-Wiedemann syndrome). The structural overgrowth is typically present from birth or becomes apparent in early childhood. When isolated and not part of a named syndrome, Q67.4 is appropriate.
3. Deviation of Nasal Septum, Congenital
A septal deviation that is present from birth — congenital in origin — as opposed to acquired deviation (J34.2). Congenital septal deviation may result from:
-
Birth trauma — compression of the nasal septum during passage through the birth canal, particularly in larger neonates or prolonged deliveries; may present as an acute finding at delivery
-
Intrauterine compression — external nasal compression from adjacent structures in utero
-
Primary developmental deviation — developmental asymmetry in septal cartilage formation
The Excludes1 note at J34.2 explicitly directs congenital deviated nasal septum to Q67.4. The distinction is clinically and historically based — if the deviation is documented as congenital or was identified at birth, Q67.4 is correct; if acquired after birth through any mechanism, J34.2 is correct.
4. Squashed or Bent Nose, Congenital
A structural nasal deformity present at birth in which the external nasal architecture is compressed, flattened, bent, or otherwise deformed. This is distinct from:
-
Acquired nasal deformity (M95.0)
-
Post-traumatic nasal deformity (sequela of nasal fracture — S02.2XXS)
-
Nasal anomalies associated with specific syndromes (Down syndrome, other chromosomal abnormalities — coded to Q90-Q99)
Congenital nasal squashing is often position-related (intrauterine positional compression) and may improve spontaneously. When persistent and requiring intervention, surgical nasal reconstruction is coded with rhinoplasty CPT codes.
Other Conditions That May Map to Q67.4
Beyond the four explicitly listed conditions, Q67.4 serves as the residual code for any congenital deformity of the skull, face, or jaw not specifically classified elsewhere in Chapter 17. Conditions that may appropriately map here include:
-
Congenital facial asymmetry not meeting Q67.0 — Q67.0 is specifically “congenital facial asymmetry” due to intrauterine compression; Q67.4 captures facial asymmetry from other congenital origins
-
Congenital jaw asymmetry — congenital unilateral undergrowth or overgrowth of the mandible (e.g., condylar hyperplasia or hypoplasia when not part of a named syndrome)
-
Congenital cranial bossing or prominence — localized frontal, parietal, or occipital bony prominence not classified under craniosynostosis (Q75.0) or other named skull malformations
-
Congenital microgenia — congenital undergrowth of the chin/mandible not attributed to a specific named syndrome
-
Congenital prognathism or retrognathism when classified as a structural congenital deformity (distinct from dentofacial anomalies M26.-)
-
Other congenital bony facial asymmetries arising from intrauterine developmental abnormalities

Note
Q67.4 vs Q75 — deformity vs malformation: The Q67 category captures deformities — structural shape abnormalities that arise from external forces during intrauterine life or positional/mechanical influences on otherwise normal tissue. The Q75 category captures malformations — abnormalities of tissue formation itself (dysostoses, premature suture fusion, bone formation errors). Q67.4 is appropriate when the deformity is mechanical/positional in origin; Q75.- is appropriate when the abnormality reflects a primary failure of tissue formation or structural dysostosis.

Code Also / Additional Coding Instructions
When Q67.4 is part of a recognized syndrome or associated with other anomalies, additional codes should be assigned:
| Scenario | Additional Code |
|---|---|
| Hemifacial atrophy with neurological involvement | G50.- (trigeminal neuralgia), G40.- (seizures), or appropriate neurological code |
| Hemifacial hypertrophy associated with Beckwith-Wiedemann syndrome | Q87.3 (Beckwith-Wiedemann) as principal + Q67.4 additional |
| Congenital nasal deviation with sleep-disordered breathing | G47.33 (OSA, pediatric) |
| Associated chromosomal anomaly | Q90-Q99 codes for identified chromosomal abnormality |
HCC (Hierarchical Condition Category) Mapping
Q67.4 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 |
Pediatric risk adjustment note:
Q67.4 is primarily a pediatric diagnosis in most clinical contexts. For pediatric commercial or Medicaid managed care plans, risk adjustment models may differ from CMS-HCC (which is Medicare-based). In pediatric risk adjustment models (e.g., state Medicaid CDPS, commercial pediatric RAF models), craniofacial congenital anomalies may carry varying weight. Verify with the specific payer’s risk model.
MS-DRG Mapping (Inpatient)
Q67.4 as a principal inpatient diagnosis groups based on whether surgical intervention is performed and the MDC. Craniofacial congenital deformities presenting for surgical correction are among the most common inpatient scenarios for this code.
Medical (Non-Surgical) Admission
| MS-DRG | Description | Trigger |
|---|---|---|
| 154 | Other Ear, Nose, Mouth, and Throat Diagnoses with MCC | Q67.4 as PDx (nasal component) + MCC |
| 155 | Other Ear, Nose, Mouth, and Throat Diagnoses with CC | Q67.4 as PDx + CC |
| 156 | Other Ear, Nose, Mouth, and Throat Diagnoses without CC/MCC | Q67.4 as PDx, no CC/MCC |
Note
MDC: MDC 03 — Ear, Nose, Mouth, and Throat (for nasal septum/nose variant) or MDC 08 — Musculoskeletal System (for skull/face/jaw variants)
Surgical (Operative) Admission
When Q67.4 is the diagnosis driving a surgical craniofacial procedure, the DRG is determined by the OR procedure performed:
| MS-DRG | Description | Trigger |
|---|---|---|
| 073 | Craniotomy with MCC | Intracranial approach for skull deformity correction + MCC |
| 074 | Craniotomy with CC | Intracranial approach + CC |
| 075 | Craniotomy without CC/MCC | Intracranial approach, no CC/MCC |
| 130 | Cranial/Facial Procedures with CC | Craniofacial reconstruction (21172-21184) + CC |
| 131 | Cranial/Facial Procedures without CC/MCC | Craniofacial reconstruction, no CC/MCC |
| 579 | Other Musculoskeletal/CT OR Procedures with MCC | If skeletal procedure drives grouping |
| 580 | Other Musculoskeletal/CT OR Procedures with CC | As above + CC |
| 581 | Other Musculoskeletal/CT OR Procedures without CC/MCC | As above, no CC/MCC |
CC/MCC Status of Q67.4: Not designated as a CC or MCC — carries no DRG severity upgrade impact as a secondary diagnosis.
POA Exempt: Yes — all congenital codes are POA exempt; no POA indicator is required on claims for Q67.4.
CPT Procedure Codes (Commonly Associated)
Q67.4 encompasses a wide range of conditions requiring diverse procedural interventions. CPT code selection depends on the specific deformity being treated (nasal, skull, facial, jaw) and the approach (open vs. endoscopic, soft tissue vs. bony).
Evaluation and Management
| CPT | Description | wRVU (approx.) | Notes |
|---|---|---|---|
| 99205 | Office visit, new patient, high complexity | 3.50 | Initial craniofacial or ENT evaluation |
| 99215 | Office visit, established patient, high complexity | 2.80 | Ongoing management |
| 99221-99223 | Initial hospital care | 1.92-3.86 | Admission for surgical planning or procedure |
| 99231-99233 | Subsequent hospital care | 0.76-1.39 | Post-surgical inpatient follow-up |
Nasal Procedures (Congenital Nasal Deformity, Deviated Septum)
| CPT | Description | wRVU (approx.) | Assistant Allowed? | Notes |
|---|---|---|---|---|

| 30520 | Septoplasty or submucous resection, with or without cartilage scoring | ~18.16 | No | Congenital septal deviation correction |
30460/30462 — Key codes for congenital nasal deformity: These two CPT codes are specifically intended for patients with significant nasal deformity (whether congenital, traumatic, or post-rhinitis) requiring surgical correction. Q67.4 is an appropriate primary diagnosis supporting medical necessity for these codes when the deformity is congenital and documented to cause functional impairment (obstruction, breathing difficulty).
Medical necessity for rhinoplasty with Q67.4: Payers frequently require documentation of functional impairment (nasal obstruction, sleep-disordered breathing, difficulty breathing) to approve rhinoplasty as reconstructive rather than cosmetic. When Q67.4 accompanies documented nasal obstruction (J34.89 or G47.33), the claim is significantly stronger. CMS explicitly lists Q67.4 as a covered diagnosis for reconstructive surgical procedures in its cosmetic and reconstructive surgery billing article.

Coding Examples
Example 1 — Congenital Deviated Nasal Septum, Septoplasty
Clinical Scenario:
A 16-year-old male has had difficulty breathing through his nose since birth. His mother reports his nose was always “bent.” ENT examination and CT document a severe congenital S-shaped septal deviation with obstruction of both nasal passages. The provider documents “congenital deviated nasal septum.” Septoplasty is performed.
ICD-10-CM:
-
Q67.4— Other congenital deformities of skull, face and jaw (congenital nasal septal deviation — primary diagnosis supporting medical necessity) -
J34.89— Other specified disorders of nose and nasal sinuses (nasal obstruction as the functional problem driving intervention)
CPT:
30520— Septoplasty or submucous resection, with or without cartilage scoring, contouring, or replacement with graft
J34.2 vs Q67.4 — critical distinction: J34.2 (deviated nasal septum) has an Excludes1 note pointing to Q67.4 for the congenital form. When the septum deviation is documented as congenital or present since birth, Q67.4 is the correct code. J34.2 is only appropriate for acquired deviations.
Example 2 — Congenital Squashed Nose, Rhinoplasty for Functional Obstruction
Clinical Scenario:
A 14-year-old female has a congenital nasal deformity described by her plastic surgeon as “congenital flattened/squashed nose” with near-complete nasal obstruction documented on rhinomanometry. The deformity was present at birth and has not resolved. The surgeon performs a full rhinoplasty with septum correction and osteotomies to reconstruct the nasal dorsum and open the airway.
ICD-10-CM:
-
Q67.4— Other congenital deformities of skull, face and jaw (squashed nose, congenital — explicitly included) -
J34.89— Other specified disorders of nose and nasal sinuses (nasal obstruction — functional impairment)
CPT:
30462— Rhinoplasty for nasal deformity; tip, septum, and osteotomies (comprehensive rhinoplasty with bony correction)
Payer documentation tip: Include rhinomanometry or acoustic rhinometry results in the record, plus clinical photographs, to support medical necessity for rhinoplasty under Q67.4. Payers are more likely to approve reconstructive rhinoplasty when objective evidence of functional obstruction is documented alongside the congenital diagnosis.
Example 3 — Congenital Hemifacial Hypertrophy, Surgical Reduction
Clinical Scenario:
A 17-year-old male has progressive asymmetric facial overgrowth affecting the right side of his face, including the right mandible, maxilla, and soft tissue. Workup identifies no syndromic etiology. The surgeon documents “congenital hemifacial hypertrophy, right.” After completion of facial growth, the patient undergoes mandibular ramus osteotomy with reduction on the right side.
ICD-10-CM:
Q67.4— Other congenital deformities of skull, face and jaw (congenital hemifacial hypertrophy — explicitly included)
CPT:
-
21209— Osteoplasty, facial bones, reduction (for bony reduction of hypertrophied mandible/facial skeleton) -
21193— Reconstruction of mandibular rami without bone graft (if ramus remodeling is performed)
Assistant surgeon: Yes for 21193 (allowed); No for 21209 (verify per MPFS indicator).
Example 4 — Congenital Skull Depression, Cranial Contouring
Clinical Scenario:
A 4-month-old male has a localized left parietal skull depression present since birth, confirmed on CT to be an isolated calvarial depression without intracranial pathology or neural tube defect. The neurosurgeon documents “congenital depression in skull, left parietal.” Surgical elevation and contouring of the bony depression is planned at age 12 months.
ICD-10-CM:
Q67.4— Other congenital deformities of skull, face and jaw (congenital depression in skull — explicitly included)
CPT (at surgical correction):
-
21181— Contour cranial bone lesion, using existing cranial bone, without bone graft (if sufficient adjacent bone is used for contouring) -
OR
21182— Reconstruction of orbital walls, rims, forehead with grafts, ≤ 5 cm² (if bone graft is required to fill the depression)
Assistant surgeon: No for 21181; Yes for 21182.
Example 5 — Congenital Hemifacial Atrophy with Fat Grafting
Clinical Scenario:
A 22-year-old female has progressive left hemifacial atrophy (Romberg disease), congenital/developmental in origin, with involvement of the skin, subcutaneous tissue, and underlying bone of the left face. She presents for autologous fat grafting to restore volume to the left cheek, periorbital, and temporal regions.
ICD-10-CM:
Q67.4— Other congenital deformities of skull, face and jaw (congenital hemifacial atrophy — explicitly included)
CPT:
-
15772— Lipograft, autologous fat grafting; face, eyelids, mouth, neck, ears, orbits (fat transfer to left hemifacial atrophy areas) -
Multiple units may be reported per payer policy for multiple separate facial regions treated
Example 6 — Q67.4 vs J34.2 — Adult Patient, Septal Deviation, No Congenital Documentation
Clinical Scenario:
A 35-year-old male presents with nasal obstruction. He does not know if his septum was always deviated. The ENT documents “deviated nasal septum” without specifying congenital vs. acquired. No birth history is available.
ICD-10-CM:
J34.2— Deviated nasal septum (no congenital documentation — default to acquired)
Coding principle: Without explicit provider documentation of congenital origin, code J34.2 (acquired deviated nasal septum). Q67.4 should only be used when the provider clearly documents the septal deviation as congenital or present from birth. Query the provider if the documentation is ambiguous and the clinical history suggests a congenital etiology.
Key Coding Pitfalls & Tips
-
Q67.4 is never a principal diagnosis for routine outpatient visits — or is it? Unlike Z codes, Q67.4 can be a principal or first-listed diagnosis in the outpatient setting when the congenital deformity itself is the reason for the visit (e.g., a new ENT consultation for congenital nasal obstruction). It is entirely appropriate as the first-listed code when the deformity is the problem being evaluated or treated.
-
Always verify congenital vs. acquired origin. The most critical coding distinction in this code’s domain is whether a condition (nasal deviation, skull asymmetry, facial deformity) is congenital (Q67.4) or acquired (J34.2, M95.0, S02.2XXS, etc.). If the provider has not explicitly documented “congenital” or “present since birth,” query before assigning Q67.4.
-
Do not use Q67.4 for dentofacial anomalies. Malocclusion, dental arch discrepancies, jaw relationship disorders, and prognathism in the dental/occlusal context belong in M26.- (dentofacial anomalies). Q67.4 is for structural bony and soft tissue deformity of the skull, face, and jaw, not for dental/occlusal pathology.
-
Do not use Q67.4 for craniosynostosis. Craniosynostosis (premature fusion of cranial sutures) is Q75.0. Q67.4 is for deformities without premature suture fusion. When the skull shape abnormality is from suture fusion, Q75.0 is the correct code regardless of the resulting head shape.
-
J34.2 has an Excludes1 pointing to Q67.4. The two codes are mutually exclusive for the same condition in the same patient — if the septal deviation is congenital, code Q67.4 only; if acquired, code J34.2 only.
-
POA exempt — never assign a POA indicator. Q67.4 is automatically POA exempt on UB-04 claims. Assigning a “Y” or “N” POA indicator to Q67.4 is not required and some encoders will flag it as an error.
-
Additional specificity through add-on codes when syndrome is identified. If the hemifacial atrophy or hypertrophy, skull depression, or jaw deformity is associated with a named syndrome (Beckwith-Wiedemann, Parry-Romberg, neurofibromatosis), code the syndrome as the principal code and Q67.4 as an additional manifestation code, unless ICD-10-CM sequencing instructions direct otherwise.
-
Document functional impairment for payer approval of surgical procedures. Q67.4-supported surgeries are more likely to receive payer approval when functional impairment (obstruction, airway compromise, masticatory dysfunction, vision impairment from orbital involvement) is explicitly documented alongside the congenital diagnosis.
