H0004 Behavioral Health Counseling — 2026 Billing Rules

H0004 (Behavioral health counseling and therapy, per 15 minutes) is the workhorse for Medicaid BH counseling. Per-15-min unit billing means every minute matters — and every documentation gap costs.

H0004 Rules 2026

• Units billed in 15-minute increments (partial units round down)
• Time must be face-to-face (or telehealth with modifier)
• Progress-note documentation required for each 15-min unit
• Concurrent billing with medication management (H0002/H0031) requires careful modifier stacking

Common Denials

1. Unit count doesn’t match documented time
2. Non-face-to-face time counted (charting, care coordination)
3. Missing supervision documentation for LMSW/LPC intern billing
4. Duplicate billing with H0033 (Oral medication administration by non-provider)

State Medicaid Variations 2026

Some states set unit caps (12 units/day = 3 hours). Others use monthly caps. MCO-specific PA rules vary.
