What Is Revenue Code 913 in Hospital Billing?

Medical billing uses a system of standardized codes to communicate services to insurance companies, ensuring uniformity in how procedures are categorized and charged. Revenue codes are part of this structure and are used on billing forms to group services into general categories for the payer. These four-digit codes provide a high-level description of the service, which helps streamline the review and payment process.

Defining Psychiatric Partial Hospitalization

Revenue Code 913 identifies charges for “Psychiatric Partial Hospitalization – Intensive” on a hospital bill. This represents a structured, intensive outpatient program for patients with psychiatric or substance abuse conditions. These programs are an alternative to inpatient psychiatric care, allowing patients to receive treatment during the day while returning home in the evening.

The code covers full-day behavioral health services that are more concentrated than standard outpatient therapy visits. It does not include charges for inpatient stays or less frequent outpatient appointments, as those are assigned different revenue codes. This separation ensures billing reflects the intensive nature of the care provided.

Examples of Services Covered

The code is used to bill for the bundle of services provided within an intensive partial hospitalization program. This includes a combination of services designed to address the patient’s specific condition, with a focus on providing a comprehensive, coordinated set of services within a therapeutic environment. These services include:

• Individual and group therapy sessions
• Diagnostic services
• Patient education
• Medication management administered as part of the structured program

Function on a Hospital Claim Form

Revenue Code 913 is entered in Form Locator 42 on the UB-04 claim form, which is the standard document used by facilities for billing. The code’s primary function is to act as a general ledger category, informing the payer that the charge line pertains to an intensive psychiatric partial hospitalization service.

This revenue code does not stand alone; it works with a more detailed coding system. Alongside the 913 code, the claim will include one or more Current Procedural Terminology (CPT) codes. The CPT codes provide the specific details of the procedures performed, such as group psychotherapy or a psychiatric diagnostic evaluation. This combination allows the insurance company to understand both the general category of the service and the precise nature of the care delivered.
