documentation Criteria
- Lack of specified organism in documentation
Applicable To
- Infectious discitis of lumbar region without specified organism
Excludes
- Pyogenic spondylitis (M46.37)
Clinical Validation Requirements
- MRI showing T2 hyperintensity in the disc and endplate erosion
- Elevated ESR >40 mm/hr and CRP >20 mg/L
Code-Specific Risks
- Risk of undercoding if organism is identified but not documented.
Coding Notes
- Ensure documentation includes imaging and lab results to support the diagnosis.
Ancillary Codes

M46.37Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Lumbar Discitis to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code M46.46.
Impact
Clinical: May lead to inappropriate treatment if organism is not specified., Regulatory: Non-compliance with coding standards., Financial: Potential for incorrect billing and reimbursement.
Mitigation Strategy
Always document organism when identified through cultures or biopsy., Use ancillary codes for identified organisms.
Impact
Reimbursement: Potential for reduced reimbursement due to incorrect coding., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data affecting patient records.
Mitigation Strategy
Ensure that documentation supports the use of M46.46 by including imaging and lab results.
Impact
High risk of audit if unspecified codes are used without supporting documentation.
Mitigation Strategy
Ensure all documentation includes specific imaging and lab results.
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.
