29 CFR §2590.715-2708

1. (a)General rule. A group health plan, and a health insurance issuer offering group health insurance coverage, must not apply any waiting period that exceeds 90 days, in accordance with the rules of this section. If, under the terms of a plan, an individual can elect coverage that would begin on a date that is not later than the end of the 90-day waiting period, this paragraph (a) is considered satisfied. Accordingly, in that case, a plan or issuer will not be considered to have violated this paragraph (a) solely because individuals take, or are permitted to take, additional time (beyond the end of the 90-day waiting period) to elect coverage.
2. (b)Waiting period defined. For purposes of this part, a waiting period is the period that must pass before coverage for an individual who is otherwise eligible to enroll under the terms of a group health plan can become effective. If an individual enrolls as a late enrollee (as defined under § 2590.701-2) or special enrollee (as described in § 2590.701-6), any period before such late or special enrollment is not a waiting period.
3. (c)Relation to a plan's eligibility criteria—(1) In general. Except as provided in paragraphs (c)(2) and (c)(3) of this section, being otherwise eligible to enroll under the terms of a group health plan means having met the plan's substantive eligibility conditions (such as, for example, being in an eligible job classification, achieving job-related licensure requirements specified in the plan's terms, or satisfying a reasonable and bona fide employment-based orientation period). Moreover, except as provided in paragraphs (c)(2) and (c)(3) of this section, nothing in this section requires a plan sponsor to offer coverage to any particular individual or class of individuals (including, for example, part-time employees). Instead, this section prohibits requiring otherwise eligible individuals to wait more than 90 days before coverage is effective. See also section 4980H of the Code and its implementing regulations for an applicable large employer's shared responsibility to provide health coverage to full-time employees.
   1. (2)Eligibility conditions based solely on the lapse of time. Eligibility conditions that are based solely on the lapse of a time period are permissible for no more than 90 days.
   2. (3)Other conditions for eligibility. Other conditions for eligibility under the terms of a group health plan are generally permissible under PHS Act section 2708, unless the condition is designed to avoid compliance with the 90-day waiting period limitation, determined in accordance with the rules of this paragraph (c)(3).
      1. (i)Application to variable-hour employees in cases in which a specified number of hours of service per period is a plan eligibility condition. If a group health plan conditions eligibility on an employee regularly having a specified number of hours of service per period (or working full-time), and it cannot be determined that a newly-hired employee is reasonably expected to regularly work that number of hours per period (or work full-time), the plan may take a reasonable period of time, not to exceed 12 months and beginning on any date between the employee's start date and the first day of the first calendar month following the employee's start date, to determine whether the employee meets the plan's eligibility condition. Except in cases in which a waiting period that exceeds 90 days is imposed in addition to a measurement period, the time period for determining whether such an employee meets the plan's eligibility condition will not be considered to be designed to avoid compliance with the 90-day waiting period limitation if coverage is made effective no later than 13 months from the employee's start date plus, if the employee's start date is not the first day of a calendar month, the time remaining until the first day of the next calendar month.
      2. (ii)Cumulative service requirements. If a group health plan or health insurance issuer conditions eligibility on an employee's having completed a number of cumulative hours of service, the eligibility condition is not considered to be designed to avoid compliance with the 90-day waiting period limitation if the cumulative hours-of-service requirement does not exceed 1,200 hours.
      3. (iii)Limitation on orientation periods. To ensure that an orientation period is not used as a subterfuge for the passage of time, or designed to avoid compliance with the 90-day waiting period limitation, an orientation period is permitted only if it does not exceed one month. For this purpose, one month is determined by adding one calendar month and subtracting one calendar day, measured from an employee's start date in a position that is otherwise eligible for coverage. For example, if an employee's start date in an otherwise eligible position is May 3, the last permitted day of the orientation period is June 2. Similarly, if an employee's start date in an otherwise eligible position is October 1, the last permitted day of the orientation period is October 31. If there is not a corresponding date in the next calendar month upon adding a calendar month, the last permitted day of the orientation period is the last day of the next calendar month. For example, if the employee's start date is January 30, the last permitted day of the orientation period is February 28 (or February 29 in a leap year). Similarly, if the employee's start date is August 31, the last permitted day of the orientation period is September 30.
4. (d)Application to rehires. A plan or issuer may treat an employee whose employment has terminated and who then is rehired as newly eligible upon rehire and, therefore, required to meet the plan's eligibility criteria and waiting period anew, if reasonable under the circumstances (for example, the termination and rehire cannot be a subterfuge to avoid compliance with the 90-day waiting period limitation).
5. (e)Counting days. Under this section, all calendar days are counted beginning on the enrollment date (as defined in § 2590.701-2), including weekends and holidays. A plan or issuer that imposes a 90-day waiting period may, for administrative convenience, choose to permit coverage to become effective earlier than the 91st day if the 91st day is a weekend or holiday.
6. (f)Examples. The rules of this section are illustrated by the following examples:
7. (g)Special rule for health insurance issuers. To the extent coverage under a group health plan is insured by a health insurance issuer, the issuer is permitted to rely on the eligibility information reported to it by the employer (or other plan sponsor) and will not be considered to violate the requirements of this section with respect to its administration of any waiting period, if both of the following conditions are satisfied:
   1. (1)The issuer requires the plan sponsor to make a representation regarding the terms of any eligibility conditions or waiting periods imposed by the plan sponsor before an individual is eligible to become covered under the terms of the plan (and requires the plan sponsor to update this representation with any changes), and
   2. (2)The issuer has no specific knowledge of the imposition of a waiting period that would exceed the permitted 90-day period.
8. (h)No effect on other laws. Compliance with this section is not determinative of compliance with any other provision of State or Federal law (including ERISA, the Code, or other provisions of the Patient Protection and Affordable Care Act). See e.g., § 2590.702, which prohibits discrimination in eligibility for coverage based on a health factor and Code section 4980H, which generally requires applicable large employers to offer coverage to full-time employees and their dependents or make an assessable payment.
9. (i)Applicability date. The provisions of this section apply for plan years beginning on or after January 1, 2015. See § 2590.715-1251 providing that the prohibition on waiting periods exceeding 90 days applies to all group health plans and group health insurance issuers, including grandfathered health plans.
