Supplementary Medical Insurance (Part B) - A Brief Description
10.3 - Supplementary Medical Insurance (Part B) - A Brief Description
(Rev. 12425, Issued: 12-21-23, Effective: 01-01-24, Implementation: 01-02-24)
To obtain SMI, an eligible individual must enroll during an enrollment period and pay the
required premiums. An individual is eligible to enroll if they are entitled to HI or are 65 years
of age and a citizen or resident alien who meets certain residence requirements. SMI provides
for payment to participating providers for furnishing covered services after a yearly cash
deductible is met. The voluntary medical insurance plan is designed to supplement the basic
hospital insurance coverage. It provides coverage for home health visits not available under
hospital insurance (e.g., no Part A entitlement or visits after the first 100 visits) and for medical
and other health services. Payment may not be made under Part B for any service that may be
paid under Part A. However, where payment is not possible under Part A (e.g., no Part A
entitlement or benefits are exhausted) payment may be made under Part B if the service is
covered.
Subject to coverage and limitations described in the Benefit Policy Publication, the following
services are covered under Part B.
