 Service retirement benefit.

 Retirement of a member on a service retirement allowance shall be made by the system as follows:

 a. Any member in service may retire upon written application to the system, setting forth at what time, not less than thirty nor more than ninety days subsequent to the execution and filing of the application, the member desires to be retired. However, the member at the time specified for retirement shall have attained the age of fifty-five and shall have served twenty-two years or more, and notwithstanding that, during the period of notification, the member may have separated from the service.
 b. Any vested member in service whose employment is terminated, other than by death or disability, prior to the member being credited with twenty-two years of service shall, upon attaining retirement age for a vested member with four or more years of service or upon application to the system for a vested member with less than four years of service, receive a service retirement allowance as calculated in the manner provided in this paragraph “b”. A vested member receiving a retirement allowance pursuant to this paragraph shall receive a service retirement allowance equal to one twenty-seconds of the retirement allowance the member would receive based on twenty-two years of service, multiplied by the number of years of service credited to the member. The amount of the retirement allowance shall be calculated in the manner provided in this paragraph using the average final compensation at the time of termination of employment.
 c. Once a person commences receiving a service retirement allowance pursuant to this section, if the person is reemployed, as defined in section 411.3, the service retirement allowance shall not be recalculated based upon the person’s reemployment.

 Ordinary disability retirement benefit.

 Upon application to the system, of a member in good standing or of the chief of the police or fire departments, respectively, any member in good standing shall be retired by the system, not less than thirty and not more than ninety days next following the date of filing the application, on an ordinary disability retirement allowance, if the medical board after a medical examination of the member certifies that the member is mentally or physically incapacitated for further performance of duty, that the incapacity is likely to be permanent, and that the member should be retired. However, if a person’s membership in the system first commenced on or after July 1, 1992, the member shall not be eligible for benefits with respect to a disability which would not exist, but for a medical condition that was known to exist on the date that membership commenced.

A member who is denied a benefit under this subsection, by reason of a finding by the medical board that the member is not mentally or physically incapacitated for the further performance of duty, shall be entitled to be restored to active service in the same position held immediately prior to the application for disability benefits. The member-in-good-standing requirement of this subsection may be waived for good cause as determined by the board. The burden of establishing good cause is on the member.

 4.

A member who has less than five years of membership service shall receive a pension equal to one-fourth of the member’s average final compensation.
 5.

 Accidental disability benefit.
 a. Upon application to the system, of a member in good standing or of the chief of the police or fire departments, respectively, any member in good standing who has become totally and permanently incapacitated for duty as the natural and proximate result of an injury or disease incurred in or aggravated by the actual performance of duty at some definite time and place, or while acting pursuant to order, outside of the city by which the member is regularly employed, shall be retired by the system if the medical board certifies that the member is mentally or physically incapacitated for further performance of duty, that the incapacity is likely to be permanent, and that the member should be retired. However, if a person’s membership in the system first commenced on or after July 1, 1992, the member shall not be eligible for benefits with respect to a disability which would not exist, but for a medical condition that was known to exist on the date that membership commenced. A medical condition shall be deemed to have been known to exist on the date that membership commenced if the medical condition is reflected in any record or document completed or obtained in accordance with the system’s medical protocols pursuant to section 400.8, or in any other record or document obtained pursuant to an application for disability benefits from the system, if such record or document existed prior to the date membership commenced. A member who is denied a benefit under this subsection, by reason of a finding by the medical board that the member is not mentally or physically incapacitated for the further performance of duty, shall be entitled to be restored to active service in the same position held immediately prior to the application for disability benefits.
 b. If a member in service or the chief of the police or fire departments becomes incapacitated for duty as a natural or proximate result of an injury or disease incurred in or aggravated by the actual performance of duty at some definite time or place or while acting, pursuant to order, outside the city by which the member is regularly employed, the member, upon being found to be temporarily incapacitated following a medical examination as directed by the city, is entitled to receive the member’s full pay and allowances from the city’s general fund or trust and agency fund until reexamined as directed by the city and found to be fully recovered or until the city determines that the member is likely to be permanently disabled. If the temporary incapacity of a member continues more than sixty days, or if the city expects the incapacity to continue more than sixty days, the city shall notify the system of the temporary incapacity. Upon notification by a city, the system may refer the matter to the medical board for review and consultation with the member’s treating physician during the temporary incapacity. Except as provided by this paragraph, the board of trustees of the statewide system has no jurisdiction over these matters until the city determines that the disability is likely to be permanent.
 c. (1) Disease under this subsection shall mean heart disease or any disease of the lungs or respiratory tract and shall be presumed to have been contracted while on active duty as a result of strain or the inhalation of noxious fumes, poison, or gases.

 (2) Disease under this subsection shall also mean cancer or infectious disease and shall be presumed to have been contracted while on active duty as a result of that duty.
 (3) However, if a person’s membership in the system first commenced on or after July 1, 1992, and the heart disease, disease of the lungs or respiratory tract, cancer, or infectious disease would not exist, but for a medical condition that was known to exist on the date that membership commenced, the presumption established in this paragraph “c” shall not apply.
 d. The requirement that a member be in good standing to apply for and receive a benefit under this subsection may be waived for good cause as determined by the board. The burden of establishing good cause is on the member.
 6.

 Retirement after accident.
 a. Upon retirement for accidental disability prior to July 1, 1990, a member shall receive an accidental disability retirement allowance which shall consist of a pension equal to sixty-six and two-thirds percent of the member’s average final compensation.
 b. Upon retirement for accidental disability on or after July 1, 1990, but before July 1, 1998, a member shall receive an accidental disability retirement allowance which shall consist of a pension equal to sixty percent of the member’s average final compensation. However, if the member has had twenty-two or more years of membership service, the member shall receive a disability retirement allowance that is equal to the greater of the retirement allowance that the member would receive under subsection 2 if the member was fifty-five years of age or the disability retirement allowance calculated under this paragraph.
 c. Upon retirement for accidental disability on or after July 1, 1998, a member shall receive an accidental disability retirement allowance which shall consist of a pension in an amount equal to the greater of sixty percent of the member’s average final compensation or the retirement allowance that the member would receive under subsection 2 if the member had attained fifty-five years of age.
 7.

 Reexamination of beneficiaries retired on account of disability.

 The system may, and upon the member’s application shall, require any disability beneficiary who has not yet attained age fifty-five to undergo a medical examination at a place designated by the medical board. The examination shall be made by the medical board or, in special cases, by an additional physician or physicians designated by such board. If any disability beneficiary who has not attained the age of fifty-five refuses to submit to the medical examination, the member’s allowance may be discontinued until withdrawal of such refusal, and if the refusal continues for one year all rights in and to the member’s pension may be revoked by the system. For a disability beneficiary who has not attained the age of fifty-five and whose entitlement to a disability retirement commenced on or after July 1, 2000, the medical board may, as part of the examination required by this subsection, suggest appropriate medical treatment or rehabilitation if, in the opinion of the medical board, the recommended treatment or rehabilitation would likely restore the disability beneficiary to duty.

 a. (1) Should any beneficiary for either ordinary or accidental disability, except a beneficiary who is fifty-five years of age or over, be engaged in a gainful occupation paying more than the difference between the member’s net retirement allowance and one and one-half times the earnable compensation of an active member at the same position on the salary scale within the member’s rank as the member held at retirement, then the amount of the member’s retirement allowance shall be reduced to an amount such that the member’s net retirement allowance plus the amount earned by the member shall equal one and one-half times the amount of the current earnable compensation of an active member at the same position on the salary scale within the member’s rank as the member held at retirement. Should the member’s earnings be later changed, the amount of the member’s retirement allowance may be further modified, provided that the new retirement allowance shall not exceed the amount of the retirement allowance adjusted by annual readjustments of pensions pursuant to subsection 12 of this section nor an amount which would cause the member’s net retirement allowance, when added to the amount earned by the beneficiary, to equal one and one-half times the amount of the earnable compensation of an active member at the same position on the salary scale within the member’s rank as the member held at retirement. A beneficiary restored to active service at a salary less than the average final compensation upon the basis of which the member was retired at age fifty-five or greater, shall not again become a member of the retirement system and shall have the member’s retirement allowance suspended while in active service. If the rank or position held by the retired member is subsequently abolished, adjustments to the allowable limit on the amount of income which can be earned in a gainful occupation shall be computed by the board of trustees as though such rank or position had not been abolished and salary increases had been granted to such rank or position on the same basis as increases granted to other ranks and positions in the department. For purposes of this paragraph, “net retirement allowance” means the amount determined by subtracting the amount paid during the previous calendar year by the beneficiary for health insurance or similar health care coverage for the beneficiary and the beneficiary’s dependents from the amount of the member’s retirement allowance paid for that year pursuant to this chapter. The beneficiary shall submit sufficient documentation to the system to permit the system to determine the member’s net retirement allowance for the applicable year.

 (2) A beneficiary retired under this lettered paragraph, in order to be eligible for continued receipt of retirement benefits, shall no later than May 15 of each year submit to the system a copy of the beneficiary’s federal individual income tax return for the preceding year. The beneficiary shall also submit, within a reasonable period of time, any documentation requested by the system that is determined to be necessary by the system to determine the beneficiary’s gross wages.
 (3) Retroactive to July 1, 1976, the limitations on pay of a member engaged in a gainful occupation who is retired under accidental disability prescribed in this paragraph shall not apply to a member who retired before July 1, 1976.
 b. Should a disability beneficiary under age fifty-five be restored to active service at a compensation not less than the disability beneficiary’s average final compensation, the disability beneficiary’s retirement allowance shall cease, the disability beneficiary shall again become a member and shall contribute thereafter at the rate established in section 411.8, and former service on the basis of which the disability beneficiary’s service was computed at the time of retirement shall be restored to full force and effect and upon subsequent retirement the disability beneficiary shall be credited with all service as a member and also with the period of disability retirement.
 c. Should a disability beneficiary under age fifty-five be employed in a public safety occupation, the disability beneficiary’s retirement allowance shall cease. Notwithstanding any provision of this chapter to the contrary, if a disability beneficiary is employed in a public safety occupation that would otherwise constitute membership service, the disability beneficiary shall not become a member of the system. For purposes of this paragraph, “public safety occupation” means a peace officer, as defined in section 97A.1; a protection occupation, as defined in section 97B.49B; a sheriff or deputy sheriff as defined in section 97B.49C; and a police officer or fire fighter as defined in section 411.1, who was not restored to active service as provided by this subsection.

 (1) An amount equal to fifty percent of the compensation earnable by the member during the year immediately preceding the member’s death if the member is in service, or an amount equal to fifty percent of the compensation earned by the member during the member’s last year of service if the member is not in service.
 (2) An amount the member would have been entitled to withdraw pursuant to section 411.23 if the member had terminated service on the date of the member’s death.
 b. (1) In lieu of the payment specified in paragraph “a”, a beneficiary meeting the qualifications of paragraph “c” may elect to receive a monthly pension equal to one-twelfth of forty percent of the average final compensation of the member, but not less than twenty percent of the average monthly earnable compensation paid to an active member of the system, as reported by the actuary. For a member not in service at the time of death, the pension shall be reduced as provided in subsection 1, paragraph “b”.

 (2) For a member not in service at the time of death, the pension shall be paid commencing when the member would have attained the age of fifty-five except that if there is a child of the member, the pension shall be paid commencing with the member’s death until the child of the member no longer meets the definition of child as provided in section 411.1. The pension shall resume when the member would have attained the age of fifty-five.
 (3) For a member in service at the time of death, the pension shall be paid commencing with the member’s death.

 c. The pension under paragraph “b” may be selected only by the following beneficiaries:

 (1) The spouse, regardless of whether the spouse was designated by the member to the system as the member’s beneficiary.
 (2) If there is no spouse, or if the spouse dies and there is a child of a member, then the member’s child or children, in equal shares. The pension to each child shall terminate when the child no longer meets the definition of child in section 411.1.
 d. If the member failed to designate a beneficiary, or if the beneficiary designated by the member predeceases the member, the benefits provided in paragraph “a” of this subsection shall be paid as follows in the following order of priority:

 (1) To the member’s surviving spouse, unless the surviving spouse selected the pension under paragraph “b”.
 (2) To the member’s surviving children, including any adult children, in equal shares.
 (3) To the member’s surviving parents, in equal shares.
 (4) To the member’s estate.

 Remarriage of surviving spouse.

 Effective July 1, 1990, for a member who died prior to July 1, 1988, if the member’s surviving spouse remarried prior to July 1, 1988, the remarriage does not make the spouse ineligible under subsection 8, paragraph “c”, subparagraphs (1) and (2), to receive benefits under subsections 8, 9, 11, and 12.

 b.

 Recomputation of benefit – surviving spouse.

 A benefit payable under this chapter to a surviving spouse and to any surviving spouse who receives a division of the surviving spouse benefit pursuant to a marriage decree or marital property order under section 411.13 shall not be recomputed upon the death of any surviving spouse.

 14.

 Beneficiary designation.

 A member may designate, in writing on a form prescribed by the system, any person or persons to whom the system will pay a death benefit under this section in the event of the member’s death. If the member is married at the time a designation is signed, a designation of a beneficiary other than the member’s spouse shall not be valid unless the member’s spouse consents in writing to the designation. A designation filed with the system shall be deemed revoked if, subsequent to the designation, a new designation is filed with the system, the member marries, or the member divorces the individual who was the member’s named beneficiary.

 15.

 Line of duty death benefit.
 a. If, upon the receipt of evidence and proof from the chief of the police or fire department that the death of a member in service was the direct and proximate result of a traumatic personal injury incurred in the line of duty, the system decides that death was so caused, there shall be paid, to a person authorized to receive an accidental death benefit as provided in subsection 9, paragraph “b”, the amount of one hundred thousand dollars, which shall be payable in a lump sum. However, for purposes of this subsection, a child who no longer meets the definition of child in section 411.1 shall be eligible to receive a line of duty death benefit pursuant to this subsection.
 b. A line of duty death benefit shall not be payable under this subsection if any of the following applies:

 (1) The death resulted from stress, strain, occupational illness, or a chronic, progressive, or congenital illness, including but not limited to a disease of the heart, lungs, or respiratory system, unless a traumatic personal injury was a substantial contributing factor to the member’s death.
 (2) The death was caused by the intentional misconduct of the member or by the member’s intent to cause the member’s own death.
 (3) The member was voluntarily intoxicated at the time of death.
 (4) The member was performing the member’s duties in a grossly negligent manner at the time of death.
 (5) An individual who would otherwise be entitled to a benefit under this subsection was, through the individual’s actions, a substantial contributing factor to the member’s death.
 (6) The death qualifies for a volunteer emergency services provider death benefit pursuant to section 100B.31.
 16.

 Ineligibility for disability benefits.
 a. A member otherwise eligible to receive a disability retirement benefit under this chapter shall not be eligible to receive such a benefit if the system determines that any of the following conditions for ineligibility applies:

 (1) The disability would not exist but for the member’s chemical dependency on a schedule I controlled substance, as defined in section 124.204, or the member’s chemical dependency on a schedule II controlled substance, as defined in section 124.206, resulting from the inappropriate use of the schedule II controlled substance. For purposes of this subparagraph, “chemical dependency” means an addiction or dependency, either physical or psychological, on a chemical substance. Persons who take medically prescribed drugs shall not be considered chemically dependent if the drug is medically prescribed and the intake is proportionate to the medical need.
 (2) The disability is a mental disability proximately caused by appropriate disciplinary actions taken against the member, or by conflicts with a superior or coworker if the superior or coworker was acting legally and appropriately toward the member when the conflicts occurred.
 b. A member otherwise eligible to receive a disability retirement benefit under this chapter, or who is receiving such a benefit, shall not be eligible to receive such a benefit beginning with the month following the determination by the system that the disability would not exist but for the action of the member for which the member has been convicted of a felony.
 c. A member eligible to commence receiving a disability benefit on or after July 1, 2000, may be ineligible to receive a disability retirement benefit if the system determines that the member’s alcoholism or drug addiction was a contributing factor material to the determination of the member’s disability. Upon a determination that the member’s alcoholism or drug addiction was a contributing factor in the member’s disability, the system shall direct the member to undergo substance abuse treatment that the medical board determines is appropriate to treat the member’s alcoholism or drug addiction. After the end of a twenty-four-month period following the member’s first month of entitlement to a disability benefit, the system shall reevaluate the member’s disability. If the system determines that the member failed to comply with the treatment program prescribed by this paragraph and that the member would not be disabled but for the member’s alcoholism or drug addiction, the member’s entitlement to a disability benefit under this chapter shall terminate effective the first day of the first month following the month the member is notified of the system’s determination.
 17.

 (2) The individual has a spouse, or a child or children, as defined in section 411.1.
 b. The amount of the retirement allowance not paid to the individual under paragraph “a” shall be paid in the following order of priority:

 (1) To the individual’s spouse, if any.
 (2) If there is no spouse, then to the individual’s child or children, as defined in section 411.1.
 c. This subsection shall not be construed in a manner that impairs the rights of any individual under a marital property, spousal support, or child support order. In addition, this subsection shall not be construed to impair the statutory rights of a governmental entity, including but not limited to the right of a governmental entity to collect an amount for deposit in the victim compensation fund established in chapter 915.
