Introduction
Billing Medicare for therapy services can be a challenge. If done incorrectly, it can lead to claim denials, delayed payments, and even compliance issues. But don’t worry—you can avoid these problems by following a structured approach. In this guide, we’ll walk you through everything you need to know about billing Medicare for therapy services without errors.
1. Understanding Medicare Coverage for Therapy Services
Before you bill Medicare, you need to understand what’s covered. Medicare provides coverage for three main types of therapy services:
- Physical Therapy (PT) – Helps patients regain movement and strength after injury or illness.
- Occupational Therapy (OT) – Focuses on improving daily living activities, such as dressing, eating, and using household objects.
- Speech-Language Pathology (SLP) – Assists with speech and swallowing disorders, particularly after a stroke or neurological condition.
Medicare Part A vs. Part B for Therapy Services
Medicare provides different coverage based on the setting in which therapy services are provided:
- Medicare Part A covers therapy services provided in hospitals, skilled nursing facilities (SNFs), and home health settings.
- Medicare Part B covers outpatient therapy services, such as those provided in private clinics, outpatient rehabilitation centers, and patients’ homes when medically necessary.
Therapy Service Settings
Therapy services are provided in different settings, such as:
- Outpatient clinics – Common for patients who need ongoing therapy but do not require hospitalization.
- Skilled nursing facilities (SNFs) – Often used for patients recovering from major surgeries, strokes, or injuries.
- Home health care – Available for patients who are homebound and require therapy services at home.
Knowing the correct coverage and setting is essential to avoid claim rejections and ensure accurate billing for occupational therapy billing services and other therapy-related claims.
