Our Story
Reliable Substance Abuse Billing Services
Credex Healthcare created a four-point review that focuses on the weak spots of substance abuse billing. Every claim goes through all four checks before it leaves our system. First, we make sure that the service and setting match the code family. An OTP visit is paid as part of the right monthly group for G2086–G2088, rather than being broken down into separate charges like a normal outpatient visit. Second, we make sure that a legal 42 CFR Part 2 permission form covers the exact information that the claim needs to be shared.
Third, for telehealth start-ups and follow-ups, we make sure that the place-of-service code and any necessary modifiers are in line with both the payer’s telehealth policy and the current DEA tele-prescribing flexibility, which has been extended until the end of 2026. Fourth, for MAT claims, we make sure that the medication billing matches the dose and administration record that was kept.
Our substance abuse billing services cover:
Claims Submission
We send in claims for substance abuse within 24 to 48 hours of session or program documentation. We make sure that the right HCPCS or CPT codes are used for the level of care (assessment, IOP, OTP, residential, or outpatient counseling), as well as the right telehealth place-of-service codes and ICD-10 codes for substance use disorder that match the clinical record before anything is sent.
Payer Enrollment
We get addiction medicine doctors, licensed addiction counselors (LADC, CADC, LCDC by state), psychiatric nurse practitioners, and OTP medical directors signed up with Medicare, Medicaid, and private insurers. We also keep track of the recredentialing cycles so that your billing never stops because of an expired enrollment.
Denial Management
Within 24 hours of a claim being denied, the reason for the denial is looked at. If there is a missing Part 2 consent, a lack of ASAM level-of-care documentation, a mismatch in telehealth policies, or an authorization that expired in the middle of an episode, we appeal it with the supporting clinical record before the payer's deadline.
Coding & Documentation Review
Our coders look over treatment plans, ASAM assessments, and progress notes to make sure that the paid code matches the level of care that was actually provided and that nothing that should be billed in an IOP day or an OTP pack is missed.
Prior Authorization
We handle prior authorization for IOP, partial hospitalization, residential treatment, and OTP induction when Medicaid or commercial plans need it. We also keep track of deadlines for concurrent review to make sure that an authorized episode doesn't expire in the middle of treatment.

Substance Abuse Billing Services Coverage
Substance abuse billing rules shift for most other specialties. They change based on the type of payer, the state Medicaid program, and policy updates for telehealth. Credex Healthcare keeps track of all three, so when you send out claims, they use the correct paperwork and code set for that month, not the set that was right last year.
Medicare Substance Abuse Billing
We bill for OTP services using the CMS combined payment structure (G2086 for the first month of office-based OUD treatment, G2087 for later months, and G2088 for additional therapy). For every claim, we follow CMS paperwork standards for medical necessity.
Medicaid Substance Abuse Billing
Different states have different rules about how many sessions can be billed, how much an ASAM level permission is needed, and how managed care organizations should send in claims. We keep track of the version that is in effect in your state, which includes any Section 1115 IMD waiver rules that affect coverage for residential and inpatient care.
Commercial Payer Billing
We handle prior authorization, benefit verification, and claims submission for IOP, PHP, and OTP services covered by BCBS, Cigna, Aetna, UnitedHealthcare, and regional carriers. We follow each payer's current telehealth policy and SUD parity requirements.
Telehealth Substance Abuse Billing
We bill telehealth SUD visits, such as buprenorphine inductions done under the DEA's expanded tele-prescribing flexibility, with the correct place-of-service codes, modifiers, and state-specific telehealth parity rules. This way, you can keep getting paid for telehealth services even as the flexibility timeline changes.

The Right Documentation
Most denials for substance abuse can be traced back to five specific failure points. Each one is caught by a specialized billing team before the claim leaves the practice. Here's where Credex Healthcare closes the gap.
NPI & Credential Verification
Before any claim is sent out, we make sure that each addiction medicine doctor, LADC/CADC counselor, and OTP medical director billing under the group NPI is currently registered with the target payer and has up-to-date taxonomy codes and DEA registration.
CPT Code Review
Our coders confirm that the claim uses the right code family for the setting, whether that's an IOP per diem, an OTP bundle, a normal outpatient HCPCS code, or a drug-testing code. They also make sure that no session is paid under a code that was made for a different level of care.
Documentation Review
We audit treatment plans and ASAM level-of-care reports to make sure that the paperwork backs up the level of care that was paid and that the ICD-10 diagnosis of drug use disorder is detailed enough to meet the requirements of medical necessity for payers.
Prior Authorization Tracking
We manage authorization that IOP, PHP, home, and OTP induction are all allowed. We keep track of review dates and session limits so that an authorized treatment episode never gets turned down because approval has expired.
Telehealth Compliance
For each telehealth SUD claim, we use the right POS codes, modifiers, and state telehealth parity rules. We also keep the submission workflow up to date as the DEA's tele-prescribing extension and individual payer telehealth policies change.
AR Follow-Up
Every open substance abuse claim is tracked by payer and aging bucket. If it's been more than 45 days without payment or a formal payer determination, the claim is escalated.
Strategic Insight
Specialist Substance abuse Billing Company in the USA
Substance abuse billing punishes generalist operations. A practice that bills OTP visits like standard outpatient encounters, or bills IOP days without the programming-hour documentation behind them, leaves money on the table every single week. The substance abuse billing suite that Credex Healthcare made is based on the codes and rules that are used in this field.
These include OTP grouped payments, IOP and PHP per diems, ASAM-based permission, drug testing frequency limits, and 42 CFR Part 2 consent tracking. Individual and group therapy claims, MAT drug bills, rehab and home events are all things that we take care of. We make sure that each one is coded to the amount of care that was actually provided
Claims Submission
We send claims with the right code family, ICD-10 illness coding, and matching documents so that they are accepted on the first try instead of having to be sent again and again.
Coding & Documentation
Our coding specialists look over every treatment plan and progress note to make sure that the level of care billed matches the level of care recorded. This makes sure that your program gets all the money it is owed.
Prior Authorization Management
We start and keep track of authorizations for IOP, PHP, residential, and OTP services. This keeps you from getting denied in the middle of an episode because someone wasn't watching an authorization.
Denial Management & Appeals
Within 24 hours of being denied, each case is looked at, sorted by its cause, and either fixed or officially challenged with the supporting clinical record before the payment deadline.
Credentialing & Enrollment
We get addiction medicine doctors and licensed addiction counselors approved by Medicare, Medicaid, and private insurers. We also handle recredentialing to make sure that all of our providers can continue to be billed.
Revenue Reporting & Analytics
Every month, you'll get a report that breaks down your clean claim rate by code family, rejections by root cause, telehealth billing performance, AR age, and net collections. This way, you'll always know how much money you're making.

TESTIMONIAL
What Our Substance abuse Clients Say About Us
Licensed Psychologist
Marsh
I didn’t realize I had been billing many of my longer therapy sessions incorrectly. I was using 90834 even when my documentation supported a 60-minute session. Credex noticed the pattern during their initial review and explained when 90837 should be used based on the documented session time. They corrected the process going forward, and it made a noticeable difference in what we were being paid. I really wish we had caught this sooner.
Neuropsychological Testing Practice
Greer
Billing for neuropsychological testing can get complicated very quickly. We needed a billing team that actually understood codes such as 96130 and 96132 and how the different parts of testing should be reported. Credex understood our workflow from the start. During the first quarter with them, our testing claims were paid more consistently and our denial rate dropped from around 24% to below 5%.
Group Therapy Practice
Connell
We have seven clinicians and work with Medicaid managed care plans as well as several commercial payers. Keeping up with each clinician’s enrollment status and patients’ authorization limits had become too much for our front office. Credex took over the billing and started tracking these details for us. Within about two months, our older A/R was moving much better, and we were no longer regularly finding sessions that couldn’t be paid because an authorization limit had already been reached.
Behavioral Health Clinic
Morgan
One of our biggest problems was denied psychotherapy claims. We were fixing them after the denial instead of finding out what was causing them in the first place. Credex reviewed the claims and found recurring issues with eligibility checks, authorization details, and information being carried over incorrectly before submission. Once those problems were cleaned up, we started seeing far fewer preventable denials. It has also saved our office staff a lot of time because they aren’t constantly going back to old claims.
Psychiatry & Therapy Practice
Bennett
Our psychiatrists and therapists often see the same patients, so billing became confusing when medication management and psychotherapy happened around the same period. We were seeing claims come back because of coding and documentation issues, especially on more complicated visits. Credex reviewed our billing workflow with the clinical team and helped us identify what needed to be documented and billed differently. Claims are much cleaner now, and we spend far less time correcting and resubmitting them.
TIMELINE FOR SUBSTANCE ABUSE BILLING
How Our Substance abuse Billing Process Works
Step 1
Practice and Payer Mix Assessment
We look at how well you are currently coding by level of care, how well you are complying with 42 CFR Part 2 permission paperwork, and whether there are any open credentialing or registration gaps across your payer contracts.
Step 2
Credentialing and Payer Enrollment
We make sure that every provider, doctor, and qualified psychologist is properly authorized by each payer. We then begin the enrollment process for any new patients right away and keep track of it until it's finished so that payment can begin with the patient's first visit.
Step 3
Documentation and Authorization Workflow Setup
We work with your clinical team to create documentation checkpoints for Part 2 consent capture at entry, ASAM level-of-care reasoning, and tracking prior permission.
Step 4
Clean Claim Submission
Before it Is Sent Electronically, every claim is checked to make sure it has the right code family, supporting documentation, telehealth codes and modifiers (if needed), ICD-10 specificity, and any needed authorization attachments.
Step 5
Denial Management & Follow-Up
Within 24 hours, denials are looked over and sorted. Our team handles disagreements about documentation, problems with telehealth policies, gaps in authorization, and denials of medical necessity one at a time, fixing each one as it comes up.
Step 6
Reporting & Ongoing Optimization
Every month, reports show the number of clean claims by code family, rejections by payer and root cause, telehealth success, old accounts receivable, and net collections. We'll talk about this with your bosses and make changes to the process payer by payer.

Best Substance abuse Revenue Cycle Management
When it comes to billing for substance abuse, a generalist RCM operation just doesn’t have the right skills. We know at Credex Healthcare that G2086 needs at least 70 minutes of recorded care coordination and treatment planning in the first month. It’s not enough to just write down that the patient was seen. We know that H0015 needs the programming hours to pass an audit, and a final drug test billed under G0480 without the order reason on file is a surefire way to get denied.
The same thing is said about telehealth. There is usually a difference between practices that accept telehealth (97% vs. 65%). This difference is usually caused by the billing team not keeping up with the DEA’s tele-prescribing extension deadlines and each payer’s telehealth policy in real time, or finding out about a change after the claims have already been denied.
Substance abuse-Specific Billing Expertise
Our team stays up-to-date on the OTP bundle structure, ASAM-based authorization, drug testing frequency limits, 42 CFR Part 2 consent rules, and state Medicaid SUD requirements for all current programs.
Dedicated Account Management
You work with a named account manager who knows your providers, your payer contracts, and your program mix, and who flags a telehealth policy or Medicaid authorization change before it hits your claims.
Transparent Monthly Reporting
Every client gets a full monthly report that explains in simple terms the claims by code family, the first-pass acceptance rate, the denial breakdown by root cause, the performance of telehealth, the amount owed by payer, and the net collections trend.
HIPAA and 42 CFR Part 2-Compliant Operations
Credex Healthcare handles bills for drug abuse in a way that is in line with both HIPAA and the tougher government consent rules in 42 CFR Part 2. This includes the alignment changes that must be made by February 16, 2026, in order to be in line with both sets of rules. There is no option for consent tracking here. That's how the claim process works.
GET STARTED
Stop Leaving Substance abuse Revenue On The Table
Our certified billing specialists support your practice whether you’re running telehealth MAT visits, a multi-site IOP network, or a single OTP location. From a quick coding question to an urgent denial, our team is a call away.
Approved substance abuse practices get a free billing audit from Credex Healthcare.
We review your code accuracy by level of care, your denial rate by payer, your telehealth compliance against the current DEA extension, your 42 CFR Part 2 consent documentation, any open credentialing gaps, and your AR aging. There’s no obligation after the audit, and nearly every practice that runs one finds a revenue gap that closes within the first billing cycle.
FAQs
Frequently Asked Questions
What services are included in substance abuse medical billing?
Substance abuse medical billing covers the full revenue cycle for SUD services: selecting and verifying the correct code family (H0001 for assessment, H0015 for IOP, G2086-G2088 for OTP bundles, and drug-testing and MAT medication codes), insurance verification, provider credentialing, prior authorization tracking, claims submission, payment posting, denial management, and AR follow-up.
What are the most commonly used CPT codes in substance abuse billing?
The core code set includes H0001 (alcohol/drug assessment), H0004 and H0005 (individual and group counseling), H0015 (intensive outpatient program), H0020 (methadone administration), G2086-G2088 (office-based OTP bundles), 99408/G0396-G0397 (SBIRT screening and brief intervention), and G0480-G0483 (definitive drug testing). The correct code depends entirely on the level of care and setting, not just the service performed.
How can substance abuse practices reduce claim denials?
Is telehealth covered in substance abuse billing?
Yes. Medicare, Medicaid, and most commercial payers cover telehealth substance abuse services, including MAT inductions and follow-ups under the DEA’s extended tele-prescribing flexibility, currently in effect through the end of 2026. Coverage still depends on using the correct place-of-service code, any required modifier, and staying inside each payer’s specific telehealth policy, which is why telehealth acceptance rates vary so widely between billing teams.
