| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| Q66.22 | Congenital metatarsus adductus | Use when a rigid C-shaped foot deformity is present at birth. |
|
| Q68.2 | Congenital tibial torsion | Use when shinbone rotation exceeds 10° and persists beyond age 3. |
|
| Q65.89 | Other congenital deformities of hip | Use for femoral anteversion greater than 40° in children older than 8 years. |
|
| R26.2 | Difficulty walking | Use as an ancillary code if there is functional impairment due to intoeing. |

Clinical Decision Support
Always review the patient's clinical documentation thoroughly. When in doubt, choose the more specific code and ensure documentation supports it.
Key Information: ICD-10 code for intoeing
Essential facts and insights about Intoeing
Primary ICD-10-CM Codes for intoeing
Decision Criteria
clinical Criteria
- Presence of rigid C-shaped foot deformity
Applicable To
- Rigid C-shaped foot deformity
Excludes
- Flexible metatarsus adductus
Clinical Validation Requirements
- Persistent medial deviation of forefoot with inability to abduct past neutral position
Code-Specific Risks
- Misclassification if flexibility is not assessed
Coding Notes
- Ensure documentation specifies rigidity and inability to correct the foot position.
Q68.2 - Congenital tibial torsion
Use when shinbone rotation exceeds 10° and persists beyond age 3.
Applicable To
- Internal tibial rotation >10°
Excludes
- Acquired tibial torsion
Clinical Validation Requirements
- Internal rotation of tibia with thigh-foot angle -15° on goniometry
Coding Notes
Document the degree of torsion and persistence over time.
Q65.89 - Other congenital deformities of hip
Use for femoral anteversion greater than 40° in children older than 8 years.
Applicable To
- Femoral anteversion >40°
Excludes
- Developmental dysplasia of the hip
Clinical Validation Requirements
- Hip internal rotation >70° with 'kissing patellae' sign on gait observation
Coding Notes
Ensure imaging confirms the degree of anteversion.
R26.2 - Difficulty walking
Use as an ancillary code if there is functional impairment due to intoeing.
Applicable To
- Gait abnormality
Excludes
- Gait abnormality due to neurological conditions
Clinical Validation Requirements
- Frequent tripping (≥3x/week) directly attributed to intoeing pattern
Coding Notes
Always pair with a primary code that explains the cause of the gait difficulty.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Difficulty walking
R26.2Differential Codes
Alternative codes to consider when ruling out similar conditions to the primary diagnosis.
Congenital metatarsus varus
Q66.21Congenital femoral torsion
Q68.1Congenital dislocation of hip, unilateral
Q65.81Ataxic gait
R26.0Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Intoeing to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code Q66.22.
Impact
Clinical: Leads to misdiagnosis or inappropriate treatment., Regulatory: Non-compliance with documentation standards., Financial: Potential for denied claims due to insufficient documentation.
Mitigation Strategy
Include specific measurements and observations in documentation., Ensure imaging results are referenced when applicable.
Impact
Reimbursement: Leads to lower reimbursement due to missing primary diagnosis., Compliance: Non-compliance with coding guidelines requiring etiology before symptoms., Data Quality: Inaccurate representation of patient condition in medical records.
Mitigation Strategy
Always pair R26.2 with a primary code explaining the congenital cause.
Impact
Failure to sequence congenital deformity codes before symptom codes.
Mitigation Strategy
Educate coding staff on proper sequencing rules and provide examples.
Documentation errors, coding pitfalls, and audit risks are interconnected aspects of medical coding and billing. Addressing all three areas helps ensure accurate coding, optimal reimbursement, and regulatory compliance.
