- Ensure all diagnostic criteria are met before assigning this code.
S52.521A - Torus fracture of lower end of right radius, initial encounter
Use for initial encounters of torus fractures confirmed by imaging.
Applicable To
- Buckle fracture of right distal radius
Excludes
- Fracture of unspecified radius (S52.509A)
Clinical Validation Requirements
- Radiographic confirmation of fracture
- Documentation of initial encounter
Coding Notes
Document the mechanism of injury and confirm fracture type.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Differential Codes
Alternative codes to consider when ruling out similar conditions to the primary diagnosis.
Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Emergency Department Encounters to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I21.01.
Impact
Clinical: May lead to misdiagnosis or delayed treatment., Regulatory: Increases risk of audit failures., Financial: Potential for reduced reimbursement.
Mitigation Strategy
Ensure all relevant symptoms and their characteristics are documented.
Impact
Reimbursement: May result in lower reimbursement rates., Compliance: Increases risk of non-compliance with coding standards., Data Quality: Reduces the accuracy of clinical data.
Mitigation Strategy
Always document specific fracture types and use the corresponding specific codes.
Impact
Frequent use of unspecified codes can trigger audits.
Mitigation Strategy
Document specific clinical details to support the use of specific codes.
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.
