Summary
This is a Blue Cross Blue Shield of Michigan coding guidance update emphasizing proper documentation standards for Major Depressive Disorder (MDD). Providers must document MDD with specific episode type (single vs. recurrent), severity level, clinical findings (e.g., PHQ-9 scores), and current treatment status rather than using vague terms like 'depression' or 'history of depression.' This ensures claims reflect accurate diagnosis coding and reduces claim denials due to insufficient documentation.
Action Required
Immediately: Providers and billing staff must update encounter templates and clinical documentation guidelines to require specific MDD documentation including: (1) episode type (single or recurrent), (2) severity level (mild, moderate, severe), (3) clinical assessment evidence (PHQ-9 results, symptom review), and (4) treatment plan (medication, counseling, follow-up timeline). Update provider education materials and EMR templates to reflect these standards. Billing team should flag and return claims with incomplete MDD documentation (those using only 'depression,' 'MDD,' 'stable,' or 'history of') for provider clarification before submission. This applies to all new and established patient encounters with MDD diagnosis.
