The Clinical Roadmap: Navigating SOC, ROC, and DC
By Sonia Chopra Dhir, PT
For therapists in home health, OASIS is not just paperwork. It is the clinical heartbeat of the patient episode. It influences reimbursement under PDGM, quality scores, and the patient's plan of care.
SOC: Start of Care
The SOC is the most comprehensive assessment you will perform. It establishes the patient's Day 1 baseline across body systems and functional tasks, including GG items. The comprehensive assessment is generally completed within 5 calendar days of the Start of Care date.
This visit matters because it helps lock in the clinical picture and resource needs for the episode. If functional limitations are missed, the agency may be expected to deliver more care than the assessment supports.
ROC: Resumption of Care
A ROC is required when a patient returns home after an inpatient stay of 24 hours or more, such as a hospital, rehab, or SNF stay, when the stay was not only for diagnostic testing. The ROC updates the plan of care based on what changed during the facility stay: surgery, medication changes, new safety risks, functional decline, or new caregiver needs.
The ROC visit is generally completed within 2 calendar days of the facility discharge or when the agency becomes aware the patient returned home.
DC: Discharge
The Discharge OASIS is the final scorecard for the episode. It compares the patient's discharge status to the SOC baseline and helps show whether therapy improved function, safety, and readiness for the next level of care.
These end-of-episode outcomes can affect Star Ratings and Value-Based Purchasing performance. When a patient moves from heavy assistance at SOC to safer independence at discharge, the documentation should make that therapy value visible.
OASIS-E2 updates for 2026
CMS OASIS-E2 guidance is effective April 1, 2026. For ROC, clinicians should be aware that hearing, vision, and language items are now part of the assessment.
Common questions
Why does OASIS matter clinically?
OASIS helps define the clinical baseline, reimbursement picture, quality reporting, and plan of care. For therapists, it is one of the clearest ways to show skilled need and functional progress.
How do SOC, ROC, and DC differ?
SOC opens the episode and establishes the baseline. ROC updates the care plan after a qualifying inpatient stay. DC documents the final status and helps show whether therapy improved function and discharge safety.
What changed with OASIS-E2 in 2026?
CMS OASIS-E2 guidance is effective April 1, 2026. ROC now includes hearing, vision, and language items. Transportation item A1255 replaces A1250 and is added to SOC and ROC, so clinicians should confirm the current item set for each assessment type.
