Missouri Certified Registered Nurse Anesthetist license renewal and CE requirements

Summary

Missouri does not require continuing education for CRNA license renewal, which happens every two years. Missouri licenses the nurse anesthetist as an Advanced Practice Registered Nurse; RSMo 335.016(2) defines APRN as a person licensed to practise advanced practice nursing as a certified clinical nurse specialist, certified nurse midwife, certified nurse practitioner or certified registered nurse anesthetist. RSMo 335.056.2 requires the APRN licence and the registered professional nurse licence to renew at the same time, as prescribed by rule. Registered nurse licences expire April 30 of each odd-numbered year and are renewable between February 1 and April 30 of that year through the MOPRO portal. There is no grace period; the board asks nurses to renew at least three business days before the expiration date, and a lapsed licence requires a reinstatement application, additional fees and fingerprint background checks. Failure to renew and maintain the registered professional nurse licence or privilege to practise, or failure to provide the required fee and evidence of active certification or maintenance of certification, expires the APRN licence.

Missouri Certified Registered Nurse Anesthetist renewal and continuing education rules

"Not stated" means the board's pages and rules we read do not address it. We do not fill in typical values.

Missouri sets no contact hour count for a nurse anesthetist, and there is none underneath it either, which matches the state's nurse practitioner record. What a certified registered nurse anesthetist owes at renewal is the registered nurse licence kept current plus the fee and evidence of active certification or maintenance of certification, which RSMo 335.056.2 states directly. RSMo 335.016(8) defines certified registered nurse anesthetist as a registered nurse currently certified as a nurse anesthetist by the Council on Certification of Nurse Anesthetists, the National Board of Certification and Recertification for Nurse Anesthetists, or another nationally recognized certifying body approved by the board of nursing, so maintaining NBCRNA certification is a condition of holding the licence rather than a source of state continuing education hours. Missouri does not adopt NBCRNA Continued Professional Certification credit totals as a state requirement, and the four year NBCRNA cycle does not line up with the state's two year April 30 cycle. Continuing education does appear in one place, but it is an initial application alternative rather than a renewal requirement: an APRN applying for controlled substance prescriptive authority may evidence the advanced pharmacology requirement with 45 continuing education units in pharmacology within the last five years, alongside options such as a transcript or a three credit hour post-baccalaureate pharmacology course. That does not reach renewal, and Missouri's controlled substance prescriptive authority runs through delegation in a collaborative practice arrangement with a Missouri licensed physician under RSMo 334.104.

Required CE topics for Missouri certified registered nurse anesthetists

The Missouri State Board of Nursing pages and rules we read do not mandate specific subject areas for this license type. Hours may be in any approved subject.

How often does a Missouri CRNA license need to be renewed?

Certified Registered Nurse Anesthetist licenses in Missouri renew every two years. Missouri licenses the nurse anesthetist as an Advanced Practice Registered Nurse; RSMo 335.016(2) defines APRN as a person licensed to practise advanced practice nursing as a certified clinical nurse specialist, certified nurse midwife, certified nurse practitioner or certified registered nurse anesthetist. RSMo 335.056.2 requires the APRN licence and the registered professional nurse licence to renew at the same time, as prescribed by rule. Registered nurse licences expire April 30 of each odd-numbered year and are renewable between February 1 and April 30 of that year through the MOPRO portal. There is no grace period; the board asks nurses to renew at least three business days before the expiration date, and a lapsed licence requires a reinstatement application, additional fees and fingerprint background checks. Failure to renew and maintain the registered professional nurse licence or privilege to practise, or failure to provide the required fee and evidence of active certification or maintenance of certification, expires the APRN licence.

Do Missouri nurse anesthetists have to submit CE certificates at renewal?

Proof of completion must be submitted with the renewal. There is no continuing education to document. What must reach the board is evidence of active certification or maintenance of certification from a board approved national certifying body, and the APRN must notify the board within five business days of any discipline or expiration of the APRN national certification. The board publishes its list of nationally recognized certifying bodies acceptable to it on the APRN general information page.

Missouri does not issue a distinct CRNA credential. It issues an advanced practice registered nurse licence in one of four roles, and RSMo 335.016(2) names certified registered nurse anesthetist among them, so 20 CSR 2200-4.100 is the shared APRN rule. The rule's own definition of advanced practice nursing role lists the four roles and states that any RN who is a CRNA, CNM, CNP or CNS may apply for an APRN licence. The finding that there is no state continuing education is an absence, so it is worth saying how it was established: RSMo 335.056 sets out the renewal requirements in full and names only the application, the fee, the maintained registered nurse licence and evidence of active certification or maintenance of certification; the board's renewal page sets out the RN renewal mechanics with no continuing education step; and the text of 20 CSR 2200-4.100 contains no renewal hour count, its only continuing education reference being the 45 pharmacology continuing education units that an applicant may use to evidence the advanced pharmacology prerequisite when first applying for controlled substance prescriptive authority. Missouri publishes its Code of State Regulations only as PDF and Word files, which the no download rule excludes, so the rule text was read on the Cornell LII mirror and is cited as a supporting source; the statutory and board sources that carry the record's substantive values are on official hosts. The board's own detailed page, Requirements to Maintain an Active Missouri APRN License, exists only as a PDF at https://pr.mo.gov/boards/nursing/RequirementstoMaintainanActiveMissouriAPRNLicense.pdf and was not read; a person should open it to confirm nothing has been added. renewal_url points at the APRN renewal page, whose body is a heading plus that PDF link, and the RN renewal page carrying the dates is cited separately. Missouri mandates no continuing education subjects for nurses, so mandatory_topics is empty. The board does not state an audit practice or a record retention period for nurses, so those fields are null.
