| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| M46.46 | Discitis, lumbar region | Use when discitis is confirmed in the lumbar region with specific clinical findings. |
|
| M46.40 | Discitis, unspecified site | Use when discitis is diagnosed but the specific spinal region is not documented. |

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

Essential facts and insights about Discitis
Primary ICD-10-CM Codes for discitis
Decision Criteria
clinical Criteria
- MRI confirmation of lumbar disc inflammation
documentation Criteria
- Specific mention of lumbar region in provider notes
Applicable To
- Lumbar discitis
- Inflammation of lumbar disc
Excludes
- Osteomyelitis of lumbar region (M86.06)
Clinical Validation Requirements
- MRI showing inflammation in lumbar disc space
- Elevated CRP and ESR levels
- Localized lumbar pain
Code-Specific Risks
- Incorrectly using M46.40 when lumbar involvement is specified.
Coding Notes
- Ensure documentation specifies the lumbar region to avoid unspecified coding.
M46.40 - Discitis, unspecified site
Use when discitis is diagnosed but the specific spinal region is not documented.
Applicable To
- Discitis NOS
Excludes
- Specific site discitis (M46.41-M46.49)
Clinical Validation Requirements
- General symptoms of discitis without specific site identification
Coding Notes
Query provider for specific site if possible to avoid unspecified coding.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Staphylococcus aureus as the cause of diseases classified elsewhere
B95.61Differential 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 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: Inaccurate treatment planning due to lack of organism identification., Regulatory: Non-compliance with coding guidelines requiring organism specification., Financial: Potential loss of reimbursement for incomplete coding.
Mitigation Strategy
Ensure lab results are reviewed and documented, Query provider if organism is suspected but not documented
Impact
Reimbursement: May lead to lower reimbursement due to unspecified coding., Compliance: Non-compliance with specificity requirements., Data Quality: Decreases accuracy of clinical data.
Mitigation Strategy
Ensure documentation specifies the lumbar region and use M46.46.
Impact
Using M46.40 when specific site is documented.
Mitigation Strategy
Implement regular audits to ensure site-specific coding.
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.
