Account number

The number assigned by your provider (hospital, physician, home care service, etc.) when medical services were provided.

Affordable Coverage

A job-based health plan covering only the employee that costs 9.61% or less of the employee’s household income. If a job-based plan is “affordable,” and meets the “minimum value” standard, you’re not eligible for a premium tax credit if you buy a Marketplace insurance plan instead.

  • The plan used to define affordability is the lowest priced “self-only” plan the employer offers — meaning a plan covering only the employee, not dependents. This is true even if you’re enrolled in a plan that costs more or covers dependents.
  • The cost is the amount the employee would pay for the insurance, not the plan’s total premium.
  • The employee’s total household income is used. Total household income includes income from everybody in the household who’s required to file a tax return.

Example 1

  • Employee’s monthly household income = $4,083 (about $49,000 per year)
  • 9.61% of the employee’s monthly household income = $392
  • Monthly cost to the employee of the lowest-priced plan the employer offers for self-only coverage = $300
  • Is the plan affordable? YES. The employee’s share of the lowest cost self-only plan ($300) is less than 9.61% of the employee’s household income ($392).

Example 2

  • Employee’s monthly household income = $2,333 (about $28,000 per year)
  • 9.61% of the employee’s monthly household income = $224
  • Monthly cost to the employee of the lowest-priced plan the employer offers for self-only coverage = $275
  • Is the plan affordable? NO. The employee’s share of the lowest-cost self-only plan ($275) is more than 9.61% of the employee’s household income ($224).

Advance Premium Tax Credit

A tax credit you can take in advance to lower your monthly health insurance payment (or “premium”). When you apply for coverage in the Health Insurance Marketplace®, you estimate your expected income for the year. If you qualify for a premium tax credit based on your estimate, you can use any amount of the credit in advance to lower your premium.

  • If at the end of the year you’ve taken more premium tax credit in advance than you’re due based on your final income, you’ll have to pay back the excess when you file your federal tax return.
  • If you’ve taken less than you qualify for, you’ll get the difference back.

This brand-name drug will cost more than the generic version, but cost less than other brand-name drugs that are not on the formulary. If you buy brand-name drugs that are not on the formulary, you often pay more because your health plan pays more.

Balance Billing

When a provider bills you for the difference between the provider’s charge and the allowed amount. For example, if the provider’s charge is $100 and the allowed amount is $70, the provider may bill you for the remaining $30. A preferred provider may not balance bill you for covered services.

Benefit Year

A year of benefits coverage under an individual health insurance plan. The benefit year for plans bought inside or outside the Marketplace begins January 1 of each year and ends December 31 of the same year.
