Stress fracture of tibia and fibula
This range includes codes for stress fractures specifically affecting the tibia and fibula, with laterality and encounter type specificity.
Osteoporosis with pathological fracture
Used when the stress fracture is due to underlying osteoporosis.
Traumatic fracture of fibula
Differential diagnosis for traumatic fractures, not stress-related.

Decision Criteria
clinical Criteria

coding Criteria
- Use 7th character 'A' for initial encounter
Applicable To
- Initial encounter for stress fracture of right fibula
Excludes
- Traumatic fracture of right fibula (S82.831A)
Clinical Validation Requirements
- MRI showing periosteal edema and fracture line

Code-Specific Risks
- Confusion with traumatic fractures
- Incorrect 7th character usage
Coding Notes
- Ensure imaging confirms stress fracture before coding.
M84.364A - Stress fracture, left fibula, initial encounter
Use for initial diagnosis of a stress fracture in the left fibula.
Applicable To
- Initial encounter for stress fracture of left fibula
Excludes
- Traumatic fracture of left fibula (S82.832A)
Clinical Validation Requirements
- MRI showing periosteal edema and fracture line
- History of increased physical activity
Coding Notes
Ensure imaging confirms stress fracture before coding.
Ancillary Codes

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Fibular Stress Fracture to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code M84.363A.
Impact
Clinical: May lead to misdiagnosis., Regulatory: Non-compliance with documentation standards., Financial: Potential for denied claims.
Mitigation Strategy
Ensure detailed documentation of symptoms and imaging findings.
Impact
Reimbursement: Incorrect coding can lead to denied claims., Compliance: Non-compliance with ICD-10 coding guidelines., Data Quality: Inaccurate medical records and statistics.
Mitigation Strategy
Use M84.36- for stress fractures and S82.83- for traumatic fractures.
Impact
Reimbursement: May affect the DRG and reimbursement rates., Compliance: Non-compliance with ICD-10 coding guidelines., Data Quality: Inaccurate tracking of patient encounters.
Mitigation Strategy
Ensure the correct 7th character is used based on the encounter type.
Impact
High risk of audits due to frequent confusion between stress and traumatic fractures.
Mitigation Strategy
Educate coders on differentiation criteria and ensure imaging confirms diagnosis.
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.
