Specialized ABA RCM
Applied Behavior Analysis Billing & Revenue Support
Applied Behavior Analysis (ABA) clinics lose an upward of 16% to 18% of their gross revenue to authorization lapses, modifier errors, and unbilled concurrent sessions. When your clinical directors are forced to act as authorization coordinators, patient outcomes suffer and profit margins compress.
Revix MD is not a generalist medical biller. We provide specialized behavioral health billing services engineered specifically for the complexity of ABA. We manage the exact mechanics of unit tracking, tiered CPT codes, and Medicaid compliance so your team can focus entirely on clinical progress.

Precision Mastery of ABA CPT Codes (97151-97158)
ABA billing is uniquely difficult because it relies heavily on time-based units and tiered clinical staff (RBTs, BCaBAs, and BCBAs). Payer algorithms immediately reject claims where the provider taxonomy does not mathematically match the billed CPT code or the required modifier (e.g., HO, HN, HM).
Our certified coders optimize your documentation to perfectly align with Category III code transitions and standard Tier 1 ABA requirements:

Operational Billing Focus
97151
Behavior Identification Assessment
Billed in 15-min units by a QHP (BCBA). We ensure observation and report generation times are not unbundled.
97153
Adaptive Behavior Treatment
The core RBT code. We actively scrub daily notes to ensure face-to-face time accurately matches the unit multiplier.
97155
Adaptive Behavior Treatment (Protocol Mod)
The BCBA oversight code. Crucial for concurrent billing. We verify the BCBA’s active direction of the technician.
97156
Family Adaptive Behavior Treatment
Parent training. We ensure documentation supports the caregiver’s presence without the patient to prevent medical necessity denials.

Concurrent Care Logic & NCCI Edits
A significant source of lost revenue in ABA is the failure to properly bill for concurrent care. When an RBT provides direct therapy (97153) and a BCBA simultaneously provides protocol modification (97155), generalist billers often trigger federal National Correct Coding Initiative (NCCI) bundling denials.
We deploy advanced clearinghouse logic to capture this revenue safely. We ensure that:
- The BCBA is explicitly documented as directing the technician during the overlapping timeframe.
- The correct clinical modifiers (e.g., Modifier XE or XP, depending on payer-specific rules) are appended to signal to the clearinghouse that two distinct providers rendered concurrent, necessary services.
Revix MD’s proprietary automated scrubbing monitors over 4,000 distinct behavioral billing guidelines, automatically identifying and resolving potential concurrent care overlaps before submission to prevent hard denials.

Frequently Asked Questions
How do you handle ABA authorization expirations?
We monitor unit consumption daily. Our system alerts our authorization team sixty days before an expiration date or unit depletion threshold. This allows ample time to secure the necessary re-authorizations without a gap in care or forcing your clinic to eat unbilled sessions.
Can you manage billing for different state Medicaid plans?
Absolutely. We specialize in the unique Medicaid modifiers (such as U-modifiers or state-specific TS modifiers) and educational requirements for all fifty states, ensuring your RBTs and BCBAs are correctly reimbursed according to local guidelines.
Do you provide technical expertise for our existing EMR software?
Yes. We are completely software-agnostic and work daily within native behavioral health platforms like CentralReach, Rethink, and TherapyBrands. We apply our deep operational expertise utilizing secure remote access, meaning your clinical staff experiences zero workflow disruption.
How do you handle concurrent care denials for 97153 and 97155?
Concurrent care denials usually stem from missing NCCI modifiers or contradictory time punches. Our system scrubs daily session notes to ensure the BCBA’s oversight timeframe aligns perfectly with the RBT’s session, appending the required payer-specific modifiers before the claim is batched.
