Why Psychiatrists Lose Revenue on Perfectly Good Sessions

A psychiatrist documents a thorough 55-minute medication management session with a patient managing treatment-resistant depression. Clinically, nothing about the visit was ambiguous. On the claim, the time was rounded incorrectly against the CPT code's threshold, and the entire visit gets denied instead of downcoded, turning a billable encounter into unpaid work.

Psychiatric billing carries a denial rate most physicians in other specialties would find alarming, and the causes are specific enough to fix directly.

The Denial Rate Psychiatrists Are Actually Working Against

Behavioral health and psychiatric claims are denied at 15% to 20%, nearly double the 5% to 10% average for medical and surgical claims, according to the AMA's 2025 Prior Authorization Physician Survey. Time-based CPT codes, 90832, 90834, and 90837 among them, are consistently the most-audited coding area in the specialty, because reimbursement is directly tied to session length, and payers scrutinize that link closely.

Telehealth Added Another Layer in 2025 and 2026

Telehealth adoption in psychiatric care outpaced most other specialties, and the billing rules around it have shifted repeatedly since the end of the public health emergency. Place of service coding for a telehealth medication management visit is not always intuitive, and a practice still coding these visits the way it did two years ago is very likely generating avoidable denials on a growing share of its total volume, since telehealth now represents a meaningful portion of ongoing psychiatric care.

Where Psychiatric Claims Specifically Break Down

Two problems show up more often in psychiatric billing than almost anywhere else in medicine. The first is the combination of evaluation and management codes with add-on psychotherapy codes, where documentation has to clearly separate the medical decision-making supporting the E/M level from the time spent on psychotherapy, or the payer denies one or both.

The second is medical necessity documentation for ongoing treatment. Unlike a single acute visit, psychiatric care often continues for months or years, and payers periodically require fresh justification that treatment remains active and necessary, not just continued out of habit. Federal guidance is explicit that documentation must reflect medical necessity and active treatment at each encounter, not rely on a note that reads too similarly to the one before it.

The Appeal Most Psychiatrists Never File

The Mental Health Parity and Addiction Equity Act requires insurers to apply prior authorization and medical necessity criteria to psychiatric care no more restrictively than they apply to comparable medical care. When a payer denies a psychiatric claim under criteria stricter than it would use for an equivalent physical health service, that denial is appealable on parity grounds, and those appeals succeed at a meaningfully higher rate than appeals based on medical necessity alone, according to industry denial research. Most practices never make this argument because nobody is systematically checking for it.

A handful of billing habits consistently reduce denials on psychiatric claims specifically, separate from general behavioral health billing practices.

These checks apply specifically to psychiatric and medication management billing, where the mix of E/M and time-based coding creates its own distinct denial risk.

• Document start and stop times precisely, not estimated ranges. Rounded or vague time documentation is one of the most common triggers for a time-based code denial.
• Separate E/M medical decision-making from psychotherapy time explicitly in the note. Blended documentation makes it impossible for a payer to verify either code independently.
• Refresh medical necessity documentation at defined intervals for ongoing treatment. A note that looks identical to the prior visit invites an audit flag on long-term patients.
• Check every denial for a parity violation before accepting it. MHPAEA-based appeals have a stronger track record than medical necessity appeals alone.
• Confirm authorization status before each visit in an ongoing treatment series. A lapsed authorization mid-series is a preventable, common denial.
• Track denial rate by CPT code, not just overall. Time-based codes and E/M-plus-add-on combinations tend to drive a disproportionate share of psychiatric denials.

Why Downcoding Is Its Own Silent Loss

Denials get attention because they are visible on a rejection report. Downcoding does not, and it quietly costs psychiatric practices just as much. When time-based documentation is vague enough that a payer's system automatically adjusts a claim down to a shorter session code rather than denying it outright, the practice gets paid, just less than the visit actually warranted, and nobody flags it for review. Tracking paid amount against documented time, not just denial rate, is the only way to catch this pattern.

A Platform That Understands the Coding, Not Just the Diagnosis

General EHRs treat time-based psychiatric coding as an afterthought. ADS is ASAM-certified and built its behavioral health platform specifically around the documentation demands of psychiatric and medication management billing, part of why practices on the ADS behavioral health platform maintain a nearly 99% first-pass clean claim rate against a specialty average running double the industry denial rate.

Reducing psychiatric claim denials does not require seeing fewer patients or documenting more defensively. It requires a system built for exactly how this specialty bills.
