Psychiatry Billing
Psychiatry billing sits at the intersection of evaluation and management coding, psychotherapy add-ons, medication management, and behavioral health payer rules. Small documentation gaps between the E/M portion and the psychotherapy portion of a visit can cost real revenue over time. DastifyBH handles billing for solo psychiatrists, PMHNP practices, and psychiatric group practices across the United States with attention to the coding, documentation, and payer patterns that shape reimbursement in this specialty.
Psychiatry Billing Has More Moving Parts Than It Looks
A single psychiatry visit can involve an E/M service, a psychotherapy add-on, a medication management component, and separate documentation requirements for each part. Billing all of that correctly requires more than picking a code and submitting a claim.
The common breakdowns:
E/M code selected without matching documentation
The 2021 E/M coding changes allow code selection based on either time or medical decision making. Billing a 99214 without documentation that supports it under either method leads to denials or audits.
Psychotherapy add-on billed without proper separation
When psychotherapy is delivered during the same encounter as an E/M service, the psychotherapy portion must be documented as separate from the medication management portion. If the two are documented as one continuous note, the add-on code (90833, 90836, or 90838) is not billable.
Time-based billing without time documentation
When time is used to select the E/M level, total time and the activities performed must be documented. Missing time documentation leads to downcoding or denial.
Diagnostic evaluation codes billed incorrectly
90791 is used for evaluations without medical services, and 90792 is used for evaluations with medical services. Psychiatrists usually bill 90792, and mixing the two triggers denials.
PMHNP billing routed incorrectly
PMHNP claims often need to be billed under the collaborating physician for incident-to billing or under the PMHNP's own credentials, and the choice affects reimbursement.
The Codes We Work With for Psychiatry
Psychiatry uses a broader mix of codes than most behavioral health specialties.
Each of these has documentation requirements and payer rules that decide whether the claim gets paid at the level billed.
- E/M codes
99202 through 99205 for new patient visits, 99212 through 99215 for established patient visits. Selection depends on time spent or medical decision making complexity.
- Diagnostic evaluations
90791 for diagnostic evaluation without medical services (used by therapists), and 90792 for diagnostic evaluation with medical services (used by psychiatrists and PMHNPs).
- Psychotherapy add-on codes
90833 for 16 to 37 minutes of psychotherapy added to an E/M visit, 90836 for 38 to 52 minutes, and 90838 for 53 or more minutes. Documentation must show the psychotherapy time separately from the E/M time.
- Standalone psychotherapy codes
90832, 90834, and 90837 when psychotherapy is provided without an E/M component.
- Interactive complexity
90785 as an add-on when interactive complexity applies to the encounter.
- Crisis psychotherapy
90839 for 60-minute crisis sessions and 90840 for each additional 30 minutes.
- Pharmacologic management
Historically billed as 90862 (retired) and now handled through appropriate E/M codes with documentation of medication management.
- Telepsychiatry
Same base codes with telehealth modifiers and place of service codes applied based on payer rules.
E/M Coding After the 2021 Changes
The 2021 E/M coding changes shifted how office visit levels are selected. Psychiatry practices that never fully adjusted to the changes often continue billing under the old framework, which creates audit risk.
Time-based selection
Code level can be selected based on total time spent on the day of the encounter, including time before, during, and after the visit for tasks like reviewing records, coordinating care, and documentation.
Medical decision making selection
Code level can be selected based on the complexity of medical decision making, evaluated across three areas: problems addressed, data reviewed, and risk of complications or management.
The provider picks whichever method supports the higher level. Documentation must clearly support the selection method used. Selecting a higher level without matching documentation leads to downcoding, denial, or clawback during audits.
Psychotherapy Add-On Rules
Combining an E/M visit with a psychotherapy add-on is standard in psychiatry, but it comes with strict documentation rules.
- The E/M portion and psychotherapy portion must be documented separatelyThe note must show what was addressed clinically as part of medication management and E/M, and what was addressed during the psychotherapy portion. Combined documentation that does not separate the two is not billable as both codes.
- Time must be documented for the psychotherapy portionThe add-on codes are time-based. The note must show the time spent on psychotherapy, and that time must fall within the range for the code billed.
- Psychotherapy time cannot overlap with E/M timeThe two activities must be documented as sequential, not simultaneous.
Missing any of these means the add-on cannot be billed, and often the entire claim gets scrutinized more heavily.
PMHNP and Incident-To Billing
PMHNP claims get underpaid or flagged when they are billed under the wrong model. The routing decision depends on payer rules, state scope of practice, and whether incident-to conditions are met.
Direct billing under the PMHNP NPI
When the payer requires independent billing or incident-to conditions are not met
Incident-to billing under the supervising physician
When the physician initiated the treatment plan, remains involved, and payer rules allow full physician fee schedule reimbursement
Payer-by-payer setup
So claim routing matches the practice structure instead of defaulting to one model across every plan
Wrong routing either creates compliance risk or leaves reimbursement on the table. We configure this at the claim level based on how each practice actually operates.

Why Psychiatry Practices Work With DastifyBH
Most billing problems in psychiatry come from small mismatches between the note, the code, and the payer rule. We focus on the controls that protect reimbursement:
- Documentation checked against the billed E/M level before submission
- Add-on time verified separately from medication management activity
- PMHNP claims routed under the correct model by payer
- Telepsychiatry rules applied at the claim level
- Recurring denials traced back to the source instead of blindly resubmitted
