Psychotherapy, 45 minutes
ICD-10 Code
F41.1
Generalized Anxiety Disorder
Compatibility Notes
A very common combination for ongoing GAD treatment. The 45-minute session is appropriate when clinical need and patient preference do not require the full 60-minute window. Most payers accept this pairing without prior authorization. Session time must fall within 38–52 minutes.
Documentation Required
- ✓Session start and stop times confirming 38–52 minutes
- ✓Active GAD diagnosis with symptom status update
- ✓GAD-7 or equivalent symptom tracking
- ✓Therapeutic content and interventions documented
- ✓Functional status update
Common Denial Reasons
- ✗Session time outside the 38–52 minute range — use 90832 or 90837 as appropriate
- ✗Notes are too brief to justify a psychotherapy code
- ✗Diagnosis documented as F41.9 when F41.1 criteria are clearly met
Applicable Modifiers
Reimbursement Notes
OON UCR $100–$165. Reimbursement is lower than 90837 by approximately 25–30%. Use 90837 when session time consistently exceeds 52 minutes.
