§493.855 Standard: Cytology: gynecologic examinations
(a) The laboratory must ensure that each individual engaged in the examination of
gynecologic preparations is enrolled in a proficiency testing program approved by
CMS by January 1, 1995, if available in the State in which he or she is employed.
Interpretive Guidelines §493.855(a)
Confirm by review of the attestation of enrollment documentation that all the individuals
examining gynecologic cytology slides are enrolled in a CMS-approved cytology PT
program.
If an individual works at more than one laboratory, the individual will be required to
indicate, prior to the first testing event, one laboratory as the primary laboratory where
the individual will be tested. Each laboratory is responsible for ensuring that all
individuals examining gynecologic preparations in their laboratory indicate a location of
testing.
Pathologists who routinely examine gynecologic cytology slide preparations, only after
they have been examined and marked by a cytotechnologist, may be tested by one of two
methods:
a. Using a test that has been previously examined or marked by a cytotechnologist in their
laboratory accompanied by the cytotechnologist’s PT answers, or
b. Using a test set that has not been previously examined.
A pathologist, who examine and interprets slide preparations without pre-screening by a
cytotechnologist, must be tested using a test set that has not been previously examined.
Each individual participating in a CMS-approved Cytology PT Program will be assigned
a unique national PT registration number (PRT#) that will remain, regardless of the
CMS-approved PT program utilized or future places of employment. Identifying
information for individuals will be placed in a Privacy Act protected System of Records
at CMS, and its confidentiality will be maintained in accordance with applicable law.
Personnel Requirement for Cytology Proficiency Testing (PT)
Cytotechnologist—Newly Certified by ASCP
New graduates of schools of cytotechnology who have taken the Certification
Examination in Cytotechnology administered by the American Society for Clinical
Pathology (ASCP) Board of Registry (BOR) and obtained a passing score have
demonstrated an initial competency level in the examination of cervical cytology. These
newly certified individuals will not be monitored for PT by CMS throughout the calendar
year in which they passed their ASCP BOR Examination.
• New graduates of schools of cytotechnology who are employed, have taken the
Certification Examination in Cytotechnology administered by the ASCP BOR,
but have not obtained a passing score are required to participate in a CMS-approved Cytology Proficiency Testing Program.
Pathologists—Newly Board Certified
• Anatomic pathologists who are newly certified by the American Board of
Pathology or the American Osteopathic Board of Pathology have demonstrated an
initial level of competency interpreting cervical cytology specimens by passing
the examination. These newly board certified individuals will not be monitored
for PT by CMS throughout the calendar year in which they became board
certified in Anatomic Pathology.
• Cytopathologists who receive added qualifications in Cytopathology from the
American Board of Pathology or the American Osteopathic Board of Pathology
have demonstrated competency interpreting cervical cytology specimens by
passing this examination. These newly board certified individuals will not be
monitored for PT by CMS throughout the calendar year in which they became
board certified in Cytopathology.
Residents and Fellows
• Anatomic pathology residents are not required to participate in a CMS-approved
Cytology PT Program. Pathology residents are under the constant supervision of
fully licensed physicians and are not responsible for the final diagnosis of cervical
cytology specimens.
• Anatomic pathology fellows whose responsibilities in the cytology laboratory
include the examination and interpretation of gynecologic specimens must enroll
and achieve a passing score in a CMS-approved Cytology PT Program each
calendar year.
All Other Cytotechnologists and Pathologists
• All other individuals subject to Cytology PT must enroll and be tested during each
calendar year.
