True or False Statements

1. The ICD-9-CM coding system was developed in the 1980s - False
2. Modifiers -LT and -RT should be added to the code for a bilateral procedure - False
3. NEC is the equivalent of "unspecified" - False
4. ICD-9-CM procedure codes consist of alphanumeric codes - False
5. When a coder finds the ICD-9-CM code in the alphabetic index, he does not need to look it up in the tabular list also - False
6. Coding internships are typically paid experiences - False
7. The coder is responsible for documenting and authenticating legible, complete, and timely patient records - False
8. Assumption coding is considered fraudulent - True
9. The coding student reports to the supervisor at the professional practice experience (or internship) site - True
10. When coding both an acute and chronic condition, sequence the acute condition first - True

The first statement, "False," indicates that the ICD-9-CM coding system was not developed in the 1980s. The ICD-9-CM (International Classification of Diseases, 9th Revision, Clinical Modification) was actually developed in the 1970s.

The second statement, "False," is incorrect. Modifiers -LT (left side) and -RT (right side) are indeed used to indicate the side of the body on which a procedure is performed, especially for bilateral procedures.

The third statement, "False," is also incorrect. NEC (Not Elsewhere Classified) is not equivalent to "unspecified." NEC is used to classify codes for conditions or diseases that cannot be assigned to a more specific category within the same code range.

The fourth statement, "False," is inaccurate. ICD-9-CM procedure codes are not alphanumeric; they are numeric codes that consist of three to four digits, with no letters involved.

The fifth statement, "False," is incorrect. When a coder finds a code in the Alphabetic Index, they must verify it in the Tabular List to ensure accuracy and completeness of coding, as the Tabular List provides additional specificity and guidelines for code assignment.

The sixth statement, "False," is incorrect. Coding internships are often unpaid experiences, especially in healthcare settings where interns are primarily gaining practical experience and education.

The seventh statement, "False," is incorrect. While coders are responsible for ensuring accurate coding, they are not responsible for documenting patient records. Documentation is typically done by healthcare providers or other medical personnel involved in patient care.

The eighth statement, "True," is accurate. Assumption coding, where a coder assigns a code based on assumptions rather than clear documentation, is considered fraudulent and can lead to legal and ethical consequences.

The ninth statement, "True," is accurate. Coding students typically report to a supervisor or preceptor at their professional practice experience or internship site for guidance and oversight.

The tenth statement, "True," is correct. When coding both an acute and chronic condition, the acute condition is sequenced first to reflect the reason for the encounter and the primary focus of treatment.
