CPT Code
90837
Psychotherapy, 60 minutes
ICD-10 Code
F90.0
Attention-deficit hyperactivity disorder, predominantly inattentive type
Compatibility Notes
Used for psychotherapy — typically CBT for ADHD, executive functioning skills training, or coaching-adjacent therapy — for patients with predominantly inattentive ADHD. CPT 90791 (evaluation) would be used for the diagnostic evaluation session. Note that 90837 covers psychotherapy only, not neuropsychological testing; use 96130–96131 for comprehensive ADHD testing.
Documentation Required
- ✓Session start and stop times confirming 53+ minutes
- ✓ADHD-I diagnosis with documented inattentive symptoms meeting DSM-5 criteria
- ✓Functional impairment in academic, occupational, or daily living domains
- ✓Psychotherapy approach documented (CBT for ADHD, executive function training)
- ✓Coordination with prescriber if stimulant medication is part of the treatment plan
Common Denial Reasons
- ✗Notes read more like educational coaching than psychotherapy — ensure clinical content is documented
- ✗ADHD treated with psychotherapy alone when payer policy requires medication trial documentation for adults
- ✗Session time below 53 minutes without code correction
Applicable Modifiers
Reimbursement Notes
OON UCR $130–$210. ADHD psychotherapy is well-covered under mental health parity. Some plans cap ADHD therapy sessions at lower limits than MDD/anxiety — verify benefit limits before starting long-term therapy.
