V.    Academic Integrity and Student Conduct

Students and employees at Oakton Community College are required to demonstrate academic integrity and follow Oakton's Code of Academic Conduct. This code prohibits:

• cheating,
• plagiarism (turning in work not written by you, or lacking proper citation),
• falsification and fabrication (lying or distorting the truth),
• helping others to cheat,
• unauthorized changes on official documents,
• pretending to be someone else or having someone else pretend to be you,
• making or accepting bribes, special favors, or threats, and
• any other behavior that violates academic integrity.

There are serious consequences to violations of the academic integrity policy. Oakton's policies and procedures provide students a fair hearing if a complaint is made against you. If you are found to have violated the policy, the minimum penalty is failure on the assignment and, a disciplinary record will be established and kept on file in the office of the Vice President for Student Affairs for a period of 3 years.

Please review the Code of Academic Conduct and the Code of Student Conduct, both located online at

VII.  Methods of Instruction

Coding instruction will include workbook exercises followed by homework practicing coding principles.  Abstracts and actual hospital records will be used for coding practice Encoder software and grouper will be introduced. 

Course may be taught as face-to-face, hybrid or online course.

VIII. Course Practices Required

Students are required to attend classes, complete assignments, do required readings and participate in class discussions.  Students will complete assignments in a coding workbook and additional coding from instructor handouts.  The computer will be used for the encoder software and grouper.  Computer lab coding practice will include actual hands-on coding of hospital records and simulated patient cases. 

Course may be taught as face-to-face, hybrid or online course.

IX.   Instructional Materials

Note: Current textbook information for each course and section is available on Oakton's Schedule of Classes.

3M and QuadraMed encoder software online.

ICD Coding Handbook with answers, AHA, required.

X.    Methods of Evaluating Student Progress

Evaluation will be based on quizzes, exams, and projects on a cumulative point basis. There will also be a final coding practical involving a variety of diagnoses and treatments.  The grading scale will be:

A = 100 - 90%
B = 89 - 80%
C = 79 - 70%
D = 69 - 60%
F = Below 60%

XI.   Other Course Information

Attendance Attendance is required. Absences should be reported to the instructor. It is the student’s responsibility to arrange for make up of work and to find out what assignments were given.  Absences will affect the final grade, which will by reduced by 1% of the total points for each absence.

Code of Student Conduct:  Refer to college catalog.

Class Policy on:

Late Assignments ‑ It is expected that assignments will be turned in on the due date.  If a late assignment is accepted by the instructor it must be turned in by the agreed upon date. The grade on the late assignment will be reduced by 7%.

Make‑up of Exams ‑ There will be only one make‑up allowed and only when students contact the instructor prior to the exam being given.  Make-up exam must be taken before the next class session.

Incomplete Grades ‑ It is the student's responsibility to initiate requests for an incomplete and to follow through with the procedures to remove the incomplete grade.

If you have a documented learning, psychological, or physical disability you may be entitled to reasonable academic accommodations or services. To request accommodations or services, contact the Access and Disability Resource Center at the Des Plaines or Skokie campus. All students are expected to fulfill essential course requirements. The College will not waive any essential skill or requirement of a course or degree program.

Oakton Community College is committed to maintaining a campus environment emphasizing the dignity and worth of all members of the community, and complies with all federal and state Title IX requirements.

Electronic video and/or audio recording is not permitted during class unless the student obtains written permission from the instructor. In cases where recordings are allowed, such content is restricted to personal use only. Any distribution of such recordings is strictly prohibited. Personal use is defined as use by an individual student for the purpose of studying or completing course assignments.

For students who have been approved for audio and/or video recording of lectures and other classroom activities as a reasonable accommodation by Oakton’s Access Disabilities Resource Center (ADRC), applicable federal law requires instructors to permit those recordings. Such recordings are also limited to personal use. Any distribution of such recordings is strictly prohibited.

Violation of this policy will result in disciplinary action through the Code of Student Conduct.
