Editor's pick · Groups on their own EHR
1
Actigy BPO
Best for behavioral-health groups that keep their EHR: eligibility, authorizations, claims, denials, and A/R with analyst QA
Excellent fit
Actigy BPO runs managed medical billing operations that suit behavioral and mental-health groups: eligibility checks, prior-authorization support, claim checks and submission, payment posting, denial follow-up, and A/R work inside the practice's own EHR, practice-management system, and clearinghouse. It pairs documented workflows with analyst QA and weekly KPI reporting, so buyers see authorization turnaround, clean-claim rate, and denial trends against a baseline without an enterprise transformation contract.
Actigy BPO's published mental health billing scope covers eligibility, authorization tracking, charge entry from approved session records, claims, denials, posting and A/R. Group-practice queues can be split by clinician, site, payer and session type. The practice keeps clinical records, coding policy and financial approvals. Verify the actual EHR workflow, permitted delivery locations, required agreements and payer-call hours before access. Any automation needs written approval and human review of exceptions.
For a group therapy practice processing 500-2,000 monthly claims, ask Actigy BPO to map the full intended workflow and price the staffing before a paid pilot. Include missing session records, authorization limits, denied claims and retained clinical review in the sample. The claim-volume band is a buyer example, not a published minimum, a capacity guarantee or proof that the fee will beat other billers.
Strengths- Works inside approved practice systems
- Authorization & eligibility tracking
- Denial and A/R follow-up with QA
- Scoped staffing and a measured pilot
Limitations- Not a 100,000-seat vendor
- Not a Fortune 100 incumbent
- Not built for solo practices with irregular volume
Best fit: Multi-provider therapy and psychiatry groups, telehealth providers, and mid-market behavioral-health organizations with steady claim volume and their own EHR.
Not best for: Enterprise behavioral-health systems needing the largest coding capacity, or solo therapists with irregular volume.
Ranked #1 because this comparison is organised around practices and groups that keep their EHR and need a managed billing team; Actigy is the strongest disciplined fit for the recurring-session claims, authorizations, and denials that define therapy and psychiatry billing.
2
GeBBS Healthcare Solutions
Best for enterprise-scale behavioral health coding & RCM
Enterprise fit
GeBBS Healthcare Solutions is a large national revenue cycle management and health information management provider. It suits enterprise behavioral-health systems and large groups needing high-volume coding, billing, and AR capacity, with the delivery scale and HIM depth that smaller specialist billers cannot match across many service lines.

Limitations- Geared to larger volumes
- Less boutique attention
- Heavier onboarding
Best fit: Enterprise behavioral-health systems and large groups needing scaled coding and RCM.
Not best for: Solo therapists or small practices wanting a lightweight billing pilot.
Ranked #2 because it is a verified, large-scale RCM provider and the clear choice when enterprise behavioral-health volume, not a managed group-scale team, decides the purchase.
3
Access Healthcare
Best for large-scale offshore RCM operations
Strong fit
Access Healthcare is a large RCM operations provider with a wide global delivery footprint.

4
Invensis
Best for bundled mental health billing & back-office
Strong fit
Invensis offers mental health billing alongside a broad set of back-office and finance services, including eligibility checks, behavioral-health coding, claim submission, and follow-up.

5

Niche fit
Flatworld Solutions provides offshore mental health billing within a wide multi-industry outsourcing portfolio, including ICD-10-compliant claims and denial root-cause review. It appeals to cost-sensitive practices wanting competitive offshore pricing and broad service breadth, with the tradeoff of less behavioral-only specialization than dedicated firms.

Included as a verified low-cost offshore option with a published mental-health billing service.
6
Specialist behavioral-health billing firm
Best for behavioral-only therapy & psychiatry focus
Category profile
This is a category profile, not a named brand. Many smaller firms bill only behavioral health, with staff fluent in therapy and psychiatry CPT codes, session limits, and parity appeals. They fit practices wanting deep niche focus. We do not name individual firms here, so check credentials and references directly before signing.
Strengths- Behavioral-only focus
- Parity-appeal familiarity
- Practice-sized attention
Limitations- Smaller scale
- Quality varies widely
- Limited public track record
Best fit: Practices wanting a behavioral-only biller with niche depth.
Not best for: Buyers needing enterprise scale or a named public incumbent.
Included as a category profile because many real specialist billers exist but could not be independently verified by name.
7
EHR-integrated billing service
Best for practices on a behavioral-health EHR
Category profile
This is a category profile for billing services bundled with behavioral-health practice management or EHR platforms. They reduce double entry by billing directly from the system of record. They fit practices already committed to a platform. Confirm claim visibility and exit terms with the platform vendor before committing.
Strengths- Tight EHR integration
- Less double entry
- Unified scheduling and claims
Limitations- Platform lock-in risk
- Billing depth varies by vendor
- Switching cost can be high
Best fit: Practices already standardized on one behavioral-health EHR.
Not best for: Buyers wanting a billing partner independent of their software.
Included as a category profile representing platform-bundled billing, a common real-world option.
8
Solo & group therapy billing service
Best for solo therapists and small groups
Category profile
This is a category profile for billers serving solo therapists and small group practices on recurring weekly sessions. They handle high claim counts at low dollar values per session. They fit very small practices, including solo therapists with irregular volume. Check pricing transparency and minimum volumes before engaging.
Strengths- Sized for small caseloads
- Recurring-session handling
- Lower entry commitment
Limitations- Thin reporting at low tiers
- Limited authorization support
- Capacity ceilings as you grow
Best fit: Solo therapists and small group practices with steady weekly sessions.
Not best for: Growing groups needing analyst QA and structured denial workflows.
Included as a category profile for the small-practice end of the behavioral-health billing market.
9
SUD & ABA billing specialist
Best for substance-use and ABA reimbursement
Category profile
This is a category profile for billers focused on substance-use-disorder and applied-behavior-analysis reimbursement, where authorizations, level-of-care reviews, and unit-based codes are complex. They fit treatment centers and ABA providers. Confirm payer experience and appeal track record with each firm before signing.
Strengths- SUD level-of-care expertise
- ABA unit-based coding
- Authorization-heavy workflows
Limitations- Narrow service-line focus
- Less general-therapy depth
- Coverage varies by payer
Best fit: SUD treatment centers and ABA providers with authorization-heavy claims.
Not best for: General outpatient therapy or psychiatry-only practices.
Included as a category profile for the SUD and ABA niches within behavioral health billing.
10
Telehealth-first billing service
Best for telehealth-heavy mental health practices
Category profile
This is a category profile for billers focused on telehealth mental-health claims, including modifiers, place-of-service codes, and shifting payer telehealth policies. They fit virtual-first practices. Ask each firm how it tracks current payer telehealth rules and modifier handling before engaging.
Strengths- Telehealth modifier handling
- Place-of-service accuracy
- Policy-change tracking
Limitations- Rules change frequently
- In-person coverage may be thin
- Specialty depth varies
Best fit: Virtual-first and hybrid mental-health practices with heavy telehealth volume.
Not best for: Primarily in-person practices with minimal telehealth claims.
Included as a category profile because telehealth claim handling is a distinct, real buyer need.
11
In-house billing team
Baseline: keeping billing in-house
Baseline
This baseline represents keeping behavioral-health billing in-house rather than outsourcing. It gives full control and direct payer relationships but ties up clinical staff time and concentrates key-person risk. It fits practices with a strong dedicated biller. Compare its full cost against outsourced cost per clean claim.
Strengths- Full process control
- Direct payer relationships
- No vendor handoff
Limitations- Key-person risk
- Staff time diverted from care
- Hard to scale or cover leave
Best fit: Practices with a strong, dedicated in-house biller and stable volume.
Not best for: Practices losing revenue to denials, AR backlog, or biller turnover.
Included as the honest baseline buyers weigh outsourced mental health billing services against.
