Decision Criteria
clinical Criteria
- Symptoms overlap multiple CTDs without meeting specific criteria.
documentation Criteria
- Explicit statement that criteria for specific diseases like SLE or RA are not met.
Applicable To
- Undifferentiated connective tissue disease
Clinical Validation Requirements
- Positive ANA without disease-specific antibodies
- Symptoms overlap multiple CTDs
- Absence of organ damage
Code-Specific Risks
- Using M35.9 without ruling out specific connective tissue diseases can lead to audits.
Coding Notes
- Ensure documentation explicitly states that criteria for specific connective tissue diseases are not met.
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.
