## **What is HCPCS code T2033?**
HCPCS code T2033 stands for "Residential care, not otherwise specified (NOS), waiver; per diem." This code falls under Waiver Services, which are specialized healthcare or support services provided under Medicaid waiver programs. The code represents a per-day (per diem) billing for unspecified residential care provided to individuals under waiver programs.
Waiver services typically help individuals who require long-term care and support outside of institutional settings, allowing them to receive care in residential environments tailored to their specific health or functional needs. The code T2033 is used for claims and billing to document such residential care when it does not fit into more specifically defined service categories under waiver services.
The Centers for Medicare & Medicaid Services or CMS maintains this code as part of a series of waiver service codes (T2012-T2041), which facilitate Medicaid billing for various waiver care services essential for patient support and community living.
## **HCPCS code T2033 documentation requirements**
