Decision Criteria
clinical Criteria
- Presence of systemic symptoms and positive lab tests.
Applicable To
- Primary Sjögren's syndrome
- Secondary Sjögren's syndrome
Excludes
- Keratoconjunctivitis sicca without Sjögren's (H16.22)
Clinical Validation Requirements
- Positive anti-SSA/SSB antibodies
- Focal lymphocytic sialadenitis on biopsy
- Ocular staining score ≥3
Code-Specific Risks
- Incorrectly coding without confirmation of Sjögren's criteria.
Coding Notes
- Ensure documentation supports systemic involvement for Sjögren's.
H16.22 - Keratoconjunctivitis sicca, not associated with Sjögren's
Use for isolated dry eye symptoms without systemic autoimmune confirmation.
Applicable To
- Isolated dry eye symptoms
Excludes
- Sjögren syndrome (M35.0)
Clinical Validation Requirements
- Negative anti-SSA/SSB antibodies
- Normal salivary flow rate
- Ocular staining score ≤2
Coding Notes
Ensure documentation clearly rules out systemic involvement.
Differential Codes

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Sicca Syndrome to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code M35.0.
Impact
Clinical: Potential misdiagnosis., Regulatory: Non-compliance with documentation standards., Financial: Denied claims due to insufficient documentation.
Mitigation Strategy
Ensure comprehensive documentation of test results., Differentiate between Sjögren's and non-Sjögren's sicca.
Impact
Reimbursement: Incorrect coding may lead to denied claims., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate patient records and data reporting.
Mitigation Strategy
Verify Sjögren's criteria are met with biopsy or antibody testing.
Impact
Coding M35.0 without sufficient documentation.
Mitigation Strategy
Ensure all diagnostic criteria are met and documented.
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.
