Systemic connective tissue disorders

Historical Changes

• •FY 2025: Routine maintenance updates with minor terminology clarifications
• •FY 2024: Enhanced specificity requirements for certain code ranges
• •FY 2023: Updated documentation guidelines for improved clarity

Upcoming Changes

• •Proposed updates pending review by Coordination and Maintenance Committee
• •Under consideration: Enhanced digital health integration codes

Implementation Guidance

• •Review all FY 2026 updates for M30-M36 codes before implementation
• •Always verify the most current codes in the ICD-10-CM manual
• •Ensure clinical documentation supports the selected diagnosis codes

Key Usage Points:

• •Always code to the highest level of specificity, considering the type of disorder, the affected body system, and any associated complications.
• •Use additional codes to identify any associated conditions or manifestations not covered by the combination codes.
• •When coding for systemic lupus erythematosus, use M32.9 if no organ or system is involved.
• •For polymyalgia rheumatica, use M35.3. If giant cell arteritis is present, use M31.5 instead.
• •For vasculitis, use M30-M31. The specific code will depend on the type and location of the vasculitis.

When to Use:

• ✓When a patient is diagnosed with a systemic connective tissue disorder.
• ✓When a patient with a known systemic connective tissue disorder presents with a new manifestation or complication.
• ✓When a patient's systemic connective tissue disorder is a significant factor in their current medical management.
• ✓When a patient has a history of a systemic connective tissue disorder that affects their current health status.

When NOT to Use:

• ✗When a patient has a localized connective tissue disorder. Use codes from M00-M25 instead.
• ✗When a patient has a connective tissue disorder that is secondary to another condition. Use the code for the primary condition instead.
• ✗When a patient has a connective tissue disorder that is not systemic. Use the appropriate code from M00-M99.
• ✗When a patient has a history of a systemic connective tissue disorder that does not affect their current health status. Use a code from Z80-Z87 instead.

Common Documentation Errors:

• ⚠Not documenting the specific type of disorder
