TL;DR. Behavioral health billing loses money to payer rules, not clinical gaps. Payers downcode 90837 to 90834 and deny for documentation. The CO-186 adjustment quietly shrinks what you collect. This guide covers the payer-rule traps and how to fight them. It also shows where a billing partner protects your revenue.
You have been through the payer runaround before. A payer pays your 60-minute session as a 45-minute one. Then a clean claim comes back needing more documentation. Behavioral health billing fights the payer harder than almost any specialty. Then the denials stack up, and collections quietly shrink. This is a revenue cycle problem, not a clinical one. The therapy is sound. Payer rules are where the money slips away.
Behavioral health billing runs into rules other specialties never see. Sessions are timed, so the code depends on the minutes documented. Payers scrutinize frequency, medical necessity, and supervision. Managed care carve-outs add another layer of rules. Substance use records carry extra compliance requirements under 42 CFR Part 2. Each rule is a place a clean claim can die. That is why generalist billing struggles with behavioral health.
One pattern shows up again and again. You bill 90837 for a 60-minute session. The payer pays 90834, the 45-minute code, instead. That is downcoding, and it arrives as a CO-186 adjustment. The payer requested no records, and the reimbursement just drops. AMA guidance calls automated downcoding inappropriate. The fix is not to stop billing 90837. Instead, document the time and medical necessity clearly, then appeal. When the note supports 60 minutes, the claim holds.
Behavioral health billing lives or dies on the note. Time-based codes need the start, stop, and total minutes. Medical necessity has to be explicit, not implied. Supervision and incident-to rules add their own documentation. A vague note is a downcode or a denial waiting to happen. CMS spells out the psychiatry and psychology billing rules in detail. Strong documentation up front is cheaper than an appeal later.
Ongoing therapy often needs prior authorization to keep paying. Miss the reauthorization, and a covered patient suddenly is not. Eligibility shifts mid-treatment as plans and carve-outs change. Prior authorization stays with your practice and clinical team. A billing partner can advise on the workflow, not obtain the authorization. What the partner owns is the claim, the denial, and the appeal. Catch the lapse before the claim, not after the denial.

15 to 30 percent: the denial reduction HRG clients see when payer rules are worked upfront.
Here is our lane in behavioral health billing. HRG provides coding consultation as needed, and we review your documentation against the note. Your clinicians own the coding itself. We do not perform, audit, or verify your coding. Our team knows the time-based codes and the downcoding pattern. We work your denials and appeals on 90837 and payer-rule claims. We can advise on prior authorization workflow, not obtain it. The billing runs inside your existing EHR and payer portals. No separate dashboards, no PDF reports, no offshore handoffs. When a denial lands, we respond in 24 to 48 hours. Over 26 years, that discipline has cut our clients' denials 15 to 30 percent. Our U.S.-based billers run your weekly and monthly A/R reviews. So a payer-rule leak surfaces in days, not at year-end.
If your behavioral health billing keeps getting downcoded and denied, the payer rules are the problem. Working those rules is exactly what we do. Walk through your denials with Andy Garcia before the next cycle closes. Book a billing strategy call with Andy. No pitch, no contract pressure.
Payers flag 90837 as overused and pay the shorter 90834 instead. The adjustment often arrives as a CO-186 with no records requested. Clear time and medical-necessity documentation is your defense. We appeal the downcode when the note supports the 60-minute session.
Timed codes, medical-necessity rules, and carve-outs create more failure points. Each payer sets its own frequency and documentation bars. A small gap turns a covered session into a denial. We review these claims against the payer rules before submission.
It is the federal rule protecting substance use disorder records. The rule adds consent and confidentiality requirements beyond HIPAA. Mishandling those records creates compliance risk on top of denials. We work inside your systems and respect those confidentiality rules.
No. HRG provides coding consultation as needed and reviews your documentation against payer rules. Your clinicians keep ownership of the coding. We prove the billed service and work the denial, without performing, auditing, or verifying the coding.
No. Prior authorization stays with your practice and clinical team. We can advise on the workflow, not obtain the authorization. What we own is the claim, the denial, and the appeal.
Fewer, larger payers mean more uniform and stricter rules. One policy change can hit your whole book of business. That raises the cost of a billing process that cannot keep up. We track payer-rule changes so your claims stay compliant.
Behavioral health billing is not a losing game. The payer rules are learnable, and the downcodes are appealable. Practices that work the rules, claim by claim, keep what they earn. Build the documentation and appeal habit now. See how we turn denials into recovered dollars.
