Applicable To
- Renal colic
Excludes
- Calculus of ureter (N20.2)
Clinical Validation Requirements

- Presence of hematuria and costovertebral angle tenderness
Coding Notes
Document imaging results and symptoms clearly to support this code.
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 Flank Pain to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code R10.9.
Impact
Clinical: May lead to incorrect diagnosis and treatment, Regulatory: Non-compliance with documentation standards, Financial: Potential for denied claims or reduced reimbursement
Mitigation Strategy
Ensure imaging results are included in the patient's record, Cross-check documentation before finalizing
Impact
Reimbursement: May result in lower reimbursement if a more specific code is not used., Compliance: Non-compliance with coding guidelines requiring specificity., Data Quality: Decreases accuracy of clinical data.
Mitigation Strategy
Switch to a specific code like N20.1 if imaging confirms a kidney stone.
Impact
Risk of audits due to use of non-specific codes when specific diagnoses are available.
Mitigation Strategy
Regular training on documentation and coding specificity.
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.
