1. All persons once licensed to practice chiropractic in this state shall pay on or before the license renewal date a renewal license fee and shall furnish to the board satisfactory evidence of the completion of the requisite number of hours, which shall not be less than twelve hours nor more than twenty-four hours per year, of postgraduate study or not less than twenty-four hours nor more than forty-eight hours if renewal occurs biennially. The postgraduate study required shall be a course of study approved by the board. The requisite number of hours is to be determined by the board. The board may set the requisite number of hours between the range of twelve to twenty-four hours, but may not increase the number of hours in excess of twelve hours by more than four hours in any two-year period. The board shall give advance notice of one year to all chiropractors licensed in the state before increasing the number of required hours. The educational requirements may be waived by the board upon presentation to it of satisfactory evidence of the illness of the chiropractor or for other good cause. A notice that the renewal fee will be due on the renewal date shall, on or before the first day of the month immediately preceding the renewal date, be mailed to all chiropractors licensed in the state for more than three months. Each practitioner of chiropractic shall display in his or her office, in a conspicuous place, his or her renewal license together with his or her original license showing that such practitioner of chiropractic is lawfully entitled to practice chiropractic. Failure of the licensee to receive the renewal form shall not relieve the licensee of the duty to renew his or her license and pay the fee required by this chapter.

2. Any licensee who allows his or her license to lapse by failing to renew the license as provided in sections 331.010 to 331.100 may be reinstated upon satisfactory explanation of such failure to renew his or her license and the payment of a reactivation fee and the current renewal fee. Any delinquent licensee who has been out of active practice for more than five years shall be required to return to an accredited chiropractic college for a semester of additional study in the clinical subjects prior to the board reviewing his or her request for reinstatement, and to pass a practical examination administered by the board.

3. Notwithstanding any law to the contrary any person licensed pursuant to this chapter may apply to the state board of chiropractic examiners for an inactive license status on a form furnished by the board. Upon receipt of the completed inactive status application form and the board’s determination that the license meets the requirements established by rule the board shall place the license on inactive status. A person whose license is inactive or who has discontinued the practice of chiropractic because of retirement shall be allowed to practice only on himself or herself and such person’s immediate family.

4. During any period of inactive status the licensee shall not be required to comply with the board’s requirements for continuing education.

5. If a licensee is granted inactive status the licensee may return to active status within five years of the license being placed on inactive status by notifying the board in advance in writing, paying the appropriate fees, and meeting all established requirements of the board as defined by rule excluding the licensing examination as a condition of reinstatement.
