In short

A group health plan at work must let you join if you lose other coverage, when the rule's conditions are met.
The plan must give you at least 30 days to ask. Do not wait.
If you lost the coverage because you did not pay, or for cause, this rule does not count it.

What this means

This is the federal rule for job-based health plans. It is the minimum. Your own plan may give more time. We do not have your plan, so we cannot tell you if your plan does.

The rule says a group health plan must let current employees and their dependents enroll if they lose other coverage and meet the conditions [1]. The plan must give you at least 30 days after the event to ask to enroll [2]. Once the plan gets your request, coverage must begin no later than the first day of the next calendar month [3].

Losing coverage does not count if it happened because you did not pay your premium on time, or because the coverage ended for cause [4].

We do not know if your plan gives more than 30 days. Don't know yet. Check your plan papers.

Your next step

Find the date your other coverage ended. Count 30 days from that date and ask your employer's benefits office, in writing, to enroll you. Keep a copy of your request and the date you sent it.

Check it yourself

Open the rule page above and read paragraphs (a)(3) and (a)(4). Then ask your benefits office for your plan's summary plan description and find the special enrollment section. If it gives a different number of days, tell us.
