Units exceed authorization
Plans authorize hours per code per period and deny anything over. Core MB tracks utilization by code against each authorization and submits reauthorization with treatment plan updates before hours run out.

ABA therapy medical billing services
ABA billing is built on 15-minute units, strict authorization of hours by code, and credential-based modifiers that change by payer. Claims pay when the rendering technician and supervising analyst are both credentialed and enrolled, units match session logs to the minute, and concurrent services such as protocol modification during direct treatment are billed the way each plan allows.
What makes ABA therapy billing different
Applied behavior analysis has a code set, authorization model and staffing structure that no other specialty shares.
- Assessment is reported with 97151 in 15-minute units, direct treatment by a technician with 97153, protocol modification by the analyst with 97155, and family guidance with 97156, each authorized separately by most plans.
- Group services use 97154 for technician-led groups and 97158 for analyst-led social skills groups, and 97152 covers supporting assessment by a technician under direction, with units limited by the authorization letter.
- Many Medicaid and commercial plans require credential modifiers such as HO for the BCBA, HN for a bachelor-level provider and HM for the technician, with the supervising analyst listed on the claim as directed by the payer.
- Concurrent billing of 97155 during 97153 is permitted by some payers when the analyst modifies the protocol face to face, but others deny overlapping times, so session notes must document who did what and when.
Denials we see most in ABA therapy
Every denial gets a root cause, a fix and a feedback loop, so the same denial stops coming back.
Rendering provider not enrolled
Claims fail when an RBT or BCBA is not linked to the group or credentialed with the plan. We handle enrollment for every new technician and analyst and hold claims until linkage is confirmed.
Overlapping session times
Payers reject 97155 and 97153 billed at the same time when their policy does not allow concurrent services. Core MB applies each payer's concurrent billing rule and corrects times from the session log before resubmission.

ABA therapy billing questions
Which modifiers do we put on ABA claims and why do they differ by payer?
Modifier requirements come from each plan, not from CPT. Some commercial plans want no credential modifier, while many Medicaid programs require HO, HN or HM to indicate the provider level and pay accordingly. Core MB maintains a modifier matrix per payer and applies it automatically so claims are not rejected for the wrong combination.
How do we keep from losing revenue when a treatment plan review is late?
Most payers stop paying the day the authorization period ends, and retroactive approvals are rare. We calendar every authorization end date, collect the progress data from the analyst in advance and submit the reauthorization early enough for the review to finish before the current period lapses.
Can we bill parent training when the child is not present?
Yes, 97156 covers family adaptive behavior treatment guidance and is appropriate with or without the patient present, as long as the note documents the training content and the caregiver involved. Core MB confirms the authorization includes 97156 units and that the payer has no patient-present requirement before billing.
