Best Substance Abuse Disorder Billing Services in Ontario, California

Millions of Americans are affected by SUDs, including alcohol and drug use disorders. These disorders can cause major health problems, damage personal relationships, lead to legal trouble, and disrupt daily life. Fortunately! Effective treatment options like counseling, behavioral therapies, and medication can support recovery and help individuals regain healthier, more stable lives.

To support recovery and improve access to care in Ontario, California, and beyond, healthcare providers must be reimbursed for the services they deliver. This underlines the importance of accurate and efficient Substance Abuse Disorder Billing Services in Ontario, California. Better billing leads to better access to care, better outcomes, and a stronger healthcare system for everyone affected by substance abuse. 

SUD billing is not only about submitting claims, but it involves the correct use of CPT and ICD-10 coding, compliance with 42 CFR Part 2 rules and HIPAA to protect patient privacy, and proper documentation. With the rise of telehealth in Ontario, it is also crucial for SUD providers to know that the same CPT codes are used as in-person visits.

Billing and Coding Guidelines for Substance Use Disorder 

Smarter Billing. Quicker Reimbursements. Healthier Outcomes for Every SUD Patient in Ontario, California

Coding Systems and Diagnosis Representation

In SUD billing, ICD-10-CM codes help identify the specific substance and describe the nature of the disorder. It involves abuse, dependence, withdrawal, intoxication, or psychotic symptoms. The common codes include:

• F10: Used for alcohol-related disorders, such as alcohol dependence with withdrawal.
• F11: Indicates opioid-related disorders, like opioid abuse with intoxication.
• F12: Applies to cannabis-related disorders, including cannabis dependence.
• F13: Covers sedative, hypnotic, or anxiolytic-related disorders, such as abuse with withdrawal.
• F14: Pertains to cocaine-related disorders, including cocaine intoxication.
• F15: Refers to other stimulant-related disorders, like amphetamine abuse.
• F16: Assigned to hallucinogen-related disorders, such as LSD-induced psychosis.
• F17: Identifies nicotine dependence, such as tobacco addiction.
• F18: Used for inhalant-related disorders, including volatile solvent intoxication.
• F19: Designates multiple or unspecified substance-related disorders.

Each of these codes includes additional details based on usage patterns, remission status, or related complications. The correct usage minimizes billing errors and improves documentation accuracy.

CPT Code Selection 

To record clinical encounters precisely, providers in Ontario, California use CPT codes, which represent the specific service delivered. These codes include:

• 90791, 90792: For initial psychiatric diagnostic assessments.
• 90832, 90834, 90837: For individual psychotherapy sessions lasting 30, 45, or 60 minutes.
• 90846, 90847: For family therapy sessions, with or without the patient.
• 90853: For group therapy conducted with multiple patients.
• 90863: Used for medication management provided alongside psychotherapy.
• 99408, 99409: For brief alcohol or substance misuse screening and intervention.
• G0396, G0397: For short behavioral counseling services related to substance use.

The appropriate code selection ensures providers are reimbursed accurately for their time and services.

Bundled Codes for Office-Based SUD Treatment

The CMS provides bundled G-codes for structured outpatient services, particularly for treating opioid and alcohol use disorders. These include:

• G2086: Used for 70 or more minutes of care during the first calendar month.
• G2087: Applied to 60 or more minutes of services in the following months.
• G2088: An add-on code for each extra 30 minutes of service beyond the base codes.

The providers in Ontario, California rely on these bundled codes to bill for coordinated care plans involving multiple services in one visit.

Preventive Screening and Brief Intervention

To support early intervention, CMS reimburses for preventive screenings and brief counseling aimed at reducing alcohol and substance misuse. These codes include:

• G0442: For an annual alcohol misuse screening, typically lasting 15 minutes.
• G0443: For brief face-to-face behavioral counseling tied to alcohol misuse.
• G0396: For short counseling sessions of 15 to 30 minutes.
• G0397: For extended counseling services over 30 minutes.

These services are frequently delivered in primary care settings across Ontario, California and require proper documentation of both time spent and patient risk factors.

Safety Planning and Follow-Up Services

To prevent repeat crises such as overdose or suicide, Medicare allows billing for specific crisis-related services:

• G0560: For creating a personalized safety plan for patients at risk of crisis.
• G0544: For follow-up contact services after a crisis or overdose incident.

These must be conducted by licensed professionals in Ontario, California, in accordance with CMS documentation standards.

Controlled Substance Monitoring & Lab Services

The monitoring of substance use and treatment progress, especially in Medication-Assisted Treatment (MAT), involves routine drug testing:

• CPT 80305–80307: Used for presumptive drug testing (screenings); Medicare covers up to 12 annually unless medically necessary.
• HCPCS G0480–G0483: Used for definitive drug testing based on the number of substances tested.

These codes are essential for opioid treatment programs and are widely used in office-based SUD care in Ontario, California.

Opioid Treatment Program (OTP) Billing 

Opioid Treatment Programs use specific G-codes to bill for integrated care that includes medications, therapy, and support services:

• G2067–G2083: Weekly bundled billing codes for medications such as methadone, buprenorphine, or naltrexone.
• G2076: For intake visits, including audio-only encounters if video is not possible.

The facilities in Ontario, California must document patient dosage, take-home eligibility, and therapy duration weekly to comply with CMS billing rules.

Social Determinants of Health (SDOH) Codes

To address non-medical needs that affect health outcomes, CMS introduced Community Health Integration (CHI) and Principal Illness Navigation (PIN) codes. These support care related to housing, food, and transport needs. However:

• Only clinicians in Ontario, California who can bill Evaluation and Management (E/M) services or are licensed psychologists are eligible to bill these codes.
• Mental Health Counselors (MHCs) and Marriage and Family Therapists (MFTs) are not permitted to bill under these services.

This limits usage to a defined group of providers despite the increasing need for SDOH services.

Expanded CMS Guidelines

Effective January 1, 2024, CMS officially allows MHCs and MFTs to enroll in Medicare and bill for SUD services in Ontario, California. To be eligible, these professionals must:

• Hold a master’s or doctoral degree
• Possess a valid license in (State)
• Have completed at least 3,000 hours of supervised clinical experience

They are reimbursed at 80% of 75% of the standard Medicare physician fee schedule, resulting in a lower reimbursement rate than other non-physician providers.

 

Is Your SUD Billing System Costing You Patients and Payments?

Missed reimbursements and billing mistakes in Ontario, California create serious setbacks for both patients and providers.

Inadequate Clinical Documentation Standards

Different payers in California require detailed documentation for SUD services, including therapy notes and medical necessity. In fact, missing information often leads to rejections. In Ontario, treatment centers face revenue losses when documentation doesn’t fully support the services billed.

Patient Collections During Recovery

In Ontario, California, collecting payments from patients in recovery is particularly sensitive. High deductibles and limited coverage make financial discussions difficult. Providers need compassionate communication and flexible plans to ensure compliance while maintaining trust during this vulnerable stage of treatment.

Strict Confidentiality Requirements 

Billing for SUD in Ontario, California must comply with strict federal privacy laws like 42 CFR Part 2. These rules limit what can be shared, which makes it harder to submit complete claims. Providers must balance compliance with payers’ documentation demands.

Frequent Denials 

Even small documentation errors can lead to frequent SUD claim denials. Missing progress notes, service details, or diagnosis codes delays reimbursement. Addressing these issues requires consistent charting practices and strong communication between clinical and billing teams.
