Overview
Substance use disorder billing runs on bundled weekly rates rather than individual services, which means a single date error can invalidate an entire episode. Opioid treatment programs bill Medicare through a weekly bundle, state Medicaid programs use their own H-code sets with wide variation, and residential and intensive outpatient levels need authorization tied to documented ASAM criteria. Add 42 CFR Part 2 confidentiality rules, which restrict the records you can attach to an appeal, and this becomes one of the harder specialties to collect in.
Why these claims get denied
The denial reasons we see most often in substance use disorder, and what our pre-billing checks are built to catch.
- Overlapping weekly bundles when an episode's date boundaries shift
- Residential or intensive outpatient levels billed without authorization matched to documented ASAM criteria
- State Medicaid H-codes billed using another state's definitions or units
- Provider not enrolled with the behavioral health or SUD carve-out entity
- Take-home medication supply billed without the dispensing record to support it
- Counselling add-ons billed without documented time or credentialed staff
- Appeals stalled because 42 CFR Part 2 consent wasn't obtained for records release

The kind of claim we see every week in substance use disorder, and the denial that usually follows it.
Sample claim · single date of serviceSubstance Use Disorder

G2080Additional counselling, 30 minutes$58.00
Denied: overlapping weekly episode
How we resolved itA missed dose shifted the episode start, so two bundles covered the same three days. We rebuilt the week boundaries across the month, voided the duplicate, and refiled the corrected sequence.
What we do for your practice
- Episode boundaries reconciled weekly so bundles never overlap or gap
- Authorization tracked against ASAM level with renewals filed before they lapse
- State-specific H-code and unit definitions loaded for the programs you contract with
- Enrollment verified with both the medical plan and the SUD carve-out before services bill
- Part 2-compliant consent captured up front so appeals aren't blocked later
- Counselling time documentation reviewed against the credential billing under it
- Dispensing and take-home records reconciled against billed supply

Common questions
Why do OTP weekly bundles deny as duplicates?
Because the week boundary moved. A missed dose, a late intake, or a corrected start date shifts the episode, and the next bundle then overlaps the previous one. The fix is reconciling the whole sequence rather than resubmitting a single week.
How does 42 CFR Part 2 affect appeals?
Part 2 restricts disclosure of SUD treatment records more tightly than HIPAA. Without a compliant consent that specifically covers the payer, you can't attach the clinical documentation an appeal needs. We capture that consent at intake so it's there when you need it.
Are H-codes the same in every state?
No, and that's a frequent source of denials. State Medicaid programs define their own H-code sets, units, and rate structures. A code that means a 15-minute unit in one state may mean a per-diem in another.
