## **What is the HCPCS code T1040 for?**
The HCPCS code T1040 is meant to designate the rendering of Medicaid-certified community behavioral health clinic services per day (per diem). It reflects a daily comprehensive per diem rate intended to cover a range of behavioral health services provided in outpatient clinic settings/federally qualified health centers/rural health clinics. Such services include:
- Services rendered by licensed clinical social workers
- Services rendered by licensed clinical psychologists
- Services rendered by licensed clinical professional counselors
- Services rendered by licensed marriage and family therapists
## **Documentation requirements for T1040**
As with any HCPCS code, you'll need to provide sufficient documentation before filing for a claim. In the context of this code, you'll need to familiarize yourself with coding requirements and guidelines set for Medicaid services. Here are examples of what you'll need:
- The full name of the patient/beneficiary
- The full name and credentials of the community behavioral health clinic professionals who handled the patient
- Documented completed encounters on each day for the patient/beneficiary
- Documentation of at least one threshold service performed per encounter (e.g., diagnostic evaluation, psychotherapy, crisis intervention, etc.)
- Documentation of the specific services rendered for the encounter
- Relevant information and indications concerning the patient/beneficiary's medical history and record that support the (medical) necessity for medical encounters or behavioral health encounters and services rendered to them
## **Billing requirements for T1040**
Besides the documentation requirements above, it would be best to take note of or have the following:
- 1 unit = 1 per diem, per patient/beneficiary
- Use of the HA modifier if the patient/beneficiary is below age 21; HB if they are aged 21+
- Only 1 unit is payable for the same day by the same clinic/provider. Multiple units are denied
- Any relevant CPT and ICD codes related to the patient's
- Billing of both a medical encounter and a behavioral health encounter on the same date is not allowed
- Remember that this is only for Medicaid-certified services
