| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| M46.1 | Sacroiliitis, not elsewhere classified | Use when there is confirmed inflammation of the sacroiliac joint with imaging evidence. |
|
| M53.3 | Sacroiliac joint dysfunction, not elsewhere classified | Use when there is SI joint pain but no imaging confirmation of inflammation. |

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

Primary ICD-10-CM Codes for sacroiliitis
Decision Criteria
clinical Criteria
- Presence of radiographic evidence of sacroiliitis
documentation Criteria
- Documented imaging findings showing Grade 2+ changes
Applicable To
- Confirmed inflammatory sacroiliitis
Excludes
- Mechanical back pain
Clinical Validation Requirements
- Radiographic evidence (Grade 2+ bilateral or Grade 3+ unilateral SI joint changes)
- CRP/ESR elevation
Code-Specific Risks
- Using without imaging proof can lead to denials.
Coding Notes
- Ensure imaging findings are documented to support the use of M46.1.
M53.3 - Sacroiliac joint dysfunction, not elsewhere classified
Use when there is SI joint pain but no imaging confirmation of inflammation.
Applicable To
- SI joint pain without confirmed inflammation
Excludes
- Inflammatory sacroiliitis
Clinical Validation Requirements
- Clinical diagnosis based on symptoms without imaging confirmation
Coding Notes
Appropriate for cases where imaging is not available or does not show inflammation.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Ankylosing spondylitis of unspecified sites in spine
M45.9Differential 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 Sacroiliitis to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code M46.1.
Impact
Clinical: Leads to misdiagnosis and inappropriate treatment., Regulatory: Non-compliance with coding standards., Financial: Potential for claim denials.
Mitigation Strategy
Ensure imaging is performed and documented., Educate staff on documentation requirements.
Impact
Reimbursement: Denials and reduced reimbursement rates., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Ensure imaging findings are documented before using M46.1.
Impact
Lack of imaging documentation for M46.1 can lead to audit failures.
Mitigation Strategy
Ensure all imaging findings are documented and accessible.
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.
