Riders, explained
A rider is an add-on to a base policy that changes what's covered or how much you're paid. A few are worth their cost for most physicians; some aren't.
Residual / partial disability
Pays a partial benefit if you can still work, but at reduced capacity or reduced income — for example, a surgeon who can only see patients part-time after an injury. Most carriers trigger this rider once a disability causes roughly a 15–20% or greater loss of income, with the exact threshold varying by carrier. Without this rider, many policies pay nothing unless you're fully unable to work, which misses a large share of real-world claims.
Future increase option (FIO)
Lets you increase your coverage amount later — as income rises during training or early practice — without new medical underwriting. This is especially relevant for residents and fellows buying a policy early, before their income has caught up to their eventual attending salary.
Cost-of-living adjustment (COLA)
Increases your monthly benefit over time (typically tied to CPI) while you're on claim, so a benefit that starts adequate doesn't lose real value during a long-term claim. More relevant for younger buyers who could plausibly be on claim for years or decades.
Catastrophic disability
Pays an additional benefit on top of the base policy if you can't perform a certain number of activities of daily living, or have a severe cognitive impairment — meant to cover the higher cost of care in the most severe disability scenarios.
How to think about the added cost
Each rider adds to the premium. The calculator's expert mode lets you toggle riders on and off to see the rough premium impact. Residual and FIO are the two most commonly recommended for physicians early in their career; COLA and catastrophic disability matter more the longer you expect to hold the policy.
