S22.3-S22.5Primary Range
Fracture of ribs, sternum and thoracic spine
This range includes codes for rib fractures, specifying single or multiple ribs, and flail chest.
Crush injury of thorax and traumatic amputation of part of thorax
Used when rib fractures are due to a crush injury, requiring sequencing before rib fracture codes.

| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| S22.3xxA | Fracture of one rib, initial encounter for closed fracture | Use for a single rib fracture without complications. |
|
| S22.4xxA | Fracture of multiple ribs, initial encounter for closed fracture | Use for multiple rib fractures without open wounds. |
|
| S22.5xxA | Flail chest, initial encounter | Use when flail chest criteria are met. |

Clinical Decision Support
Always review the patient's clinical documentation thoroughly. When in doubt, choose the more specific code and ensure documentation supports it.

Primary ICD-10-CM Codes for rib injury
Decision Criteria
clinical Criteria
- Confirmed single rib fracture via imaging
documentation Criteria
- Laterality must be specified
Applicable To
- Closed fracture of one rib
Excludes
- Open fracture of one rib
Clinical Validation Requirements
- X-ray or CT confirming fracture
- Documentation of laterality
Code-Specific Risks
- Incorrect laterality documentation
- Missing 7th character
Coding Notes
- Ensure laterality is documented to avoid unspecified coding.
S22.4xxA - Fracture of multiple ribs, initial encounter for closed fracture
Use for multiple rib fractures without open wounds.
Applicable To
- Closed fracture of multiple ribs
Excludes
- Open fracture of multiple ribs
Clinical Validation Requirements
- CT scan showing multiple rib fractures
- Documentation of displacement if present
Coding Notes
Document the number of ribs and any displacement.
S22.5xxA - Flail chest, initial encounter
Use when flail chest criteria are met.
Applicable To
- Flail segment of chest
Excludes
- Non-flail rib fractures
Clinical Validation Requirements
- CT showing ≥3 adjacent ribs fractured in ≥2 places
- Clinical signs of paradoxical movement
Coding Notes
Ensure clinical signs and imaging support the diagnosis.
Ancillary Codes

S28.0Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Rib Injury to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code S22.3xxA.
Impact
Clinical: May lead to inappropriate treatment decisions., Regulatory: Increases risk of audit and penalties., Financial: Potential for reduced reimbursement.
Mitigation Strategy
Always review documentation for specific details before coding.
Impact
Reimbursement: May lead to reduced reimbursement due to unspecified codes., Compliance: Increases risk of audit for unspecified coding., Data Quality: Decreases accuracy of patient records.
Mitigation Strategy
Always document the side of the rib fracture.
Impact
Reimbursement: Incorrect coding may affect DRG assignment., Compliance: Potential for coding errors leading to audits., Data Quality: Inaccurate representation of patient's condition.
Mitigation Strategy
Review imaging and clinical findings to confirm flail chest.
Impact
Coding rib fractures without specifying laterality increases audit risk.
Mitigation Strategy
Ensure documentation always includes laterality.
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.
