894.105—Who may correct an error in my enrollment?

(a) The Administrator may correct administrative errors about the processing of your enrollment or changes in enrollment.

(b) OPM may order correction of an administrative error if it receives evidence that it would be against equity (fairness) and good conscience not to order the correction. This decision is made at the discretion of OPM and is not subject to review.

(c) If the correction gives you retroactive coverage, you must pay the premiums for all periods of the retroactive coverage. These premiums will not be on a pre-tax basis (they are not subject to premium conversion).
