Summary & Overview

HCPCS Level II T2033: Residential Care NOS, Waiver Per Diem

HCPCS Level II code T2033 designates a per diem payment for residential care, not otherwise specified (NOS), provided under waiver programs. Nationally, this code captures daily residential supports funded through Medicaid waivers and related payer arrangements, making it relevant for managed care plans, state waiver administrators, and long-term services and supports (LTSS) networks. Its per diem structure affects rate-setting, utilization monitoring, and provider contracting across multiple payer types.

Key payers covered include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the code's clinical and service context, typical payment and billing considerations, and what to expect when this code appears on a claim. The publication outlines benchmark concepts, common usage scenarios in waiver-funded residential programs, and implications for billing workflows and payer-provider agreements.

Clinical & Coding Specifications

Clinical Context

Service: T2033 — Residential care, not otherwise specified (NOS), waiver; per diem

A typical patient is an adult beneficiary enrolled in a Medicaid waiver program who requires 24-hour supervised residential supports due to chronic medical, behavioral, or functional limitations that prevent safe independent living. Example scenario: a 68-year-old patient with advanced dementia, stage 3 pressure injury risk, and moderate functional dependence is approved for a home-and-community-based waiver. The payer authorizes per diem residential care under waiver rules to cover room, board, supervision, assistance with activities of daily living (ADLs), medication administration, and basic nursing oversight.

Clinical workflow: the interdisciplinary team (primary care clinician, geriatrician or internist, nurse case manager, social worker, and residential program staff) documents the medical necessity for residential placement in the care plan. The provider submits a per diem claim using T2033 with the appropriate diagnosis codes and applicable modifiers reflecting unusual circumstances (for example, increased complexity or a patient-directed transfer). Prior authorization and eligibility verification occur through the Medicaid waiver administrator prior to admission. Ongoing documentation includes daily progress notes, ADL/ILA (instrumental activities of daily living) assessments, medication administration records, and periodic clinical reassessments to support continued billing of the per diem service.

`22`	Increased procedural services	Use when the residential service required substantially greater resources than typical per diem due to extraordinary clinical care needs (e.g., intensive behavioral interventions, wound care requiring multiple daily skilled interventions).

`54`	Surgical care only	Not typically used with `T2033`; include only if a separate surgical global period overlaps and only surgical care portion is being billed by a surgeon.
