Service Rules — Overrides, Additives & Advanced Options
Purpose of Overrides
Overrides let you change service rule outputs for specific situations without creating entirely new rules. A single service rule with well-configured overrides can handle what previously required dozens of separate rules.
Two Types
Override: Changes what's already in the outputs for a specific condition. For example, swap the CPT code for a specific payer group, or change the POS code for telehealth encounters.
Additive: Adds something on top of the standard outputs. For example, add an interactive complexity add-on code when a provider checks a specific encounter attribute.
Override Trigger Types
Payer group
Program
Encounter attribute
Diagnosis
Duration range (e.g., 0–15 min = one CPT code, 16–37 min = another)
Client age (e.g., different CPT code for clients under 18)
Encounter creator
Multiple triggers can be combined with AND logic
What Can Be Changed via Override
CPT code
Claim type (professional vs. institutional)
Billing provider
Modifiers (add or remove)
Add-on codes
Value codes
Place of service
Min/max units
Secondary payer as primary (for Medicaid-as-secondary scenarios)
Calendar month claim split
Modifier Overrides
If a credential-based modifier override is not firing, the most common cause is that the provider's credential has not been added to their user profile. Add the credential under user configuration first, then configure the override trigger in the service rule.
When a provider holds multiple licenses (e.g., LPCC and LICDC), use the Credentials feature on the user profile combined with credential-based override triggers to apply the appropriate modifier per session.
Advanced Options
Custom Billed Rate
Uncheck "Use Fee Schedule" to set a flat custom rate for the rule.
Important: When a custom rate is used, add-on codes will not reference any fee schedule and will bill at $0. Keep "Use Fee Schedule" checked if you want payer-specific rates to apply to add-on codes.
Fence Post Rules (Bundling)
When bundling is enabled, these settings control billing on admit and discharge days:
Bill for admit day: Bill for the day even if the client was admitted partway through.
Do not bill for discharge day: No billing on the discharge day even if services occurred.
This is the standard configuration for IOP, PHP, detox, and residential programs.
Autogen
Automatically generates services without requiring a documented encounter.
Common for residential treatment on days when clients are present but no clinical encounters are logged.
Services run on a nightly sweep — expect a delay of up to one day after a change.
Multiple autogen rules can run for the same client on the same day.
If a client is discharged and readmitted on the same day, no per-diem service will be generated for that day.
Force Services to Separate Claims
Force each service to its own claim: Toggle in Advanced Options.
Split by calendar month: Automatically splits claims when services span a month boundary. Required for certain payer configurations including MN Medicaid.
Secondary Payer as Primary
A toggle that bills the secondary insurance as if it were the primary. Used for Medicaid-as-secondary scenarios where Medicaid wants to be billed first for specific service codes.
