The Complete Diagnosis Coding Book

Answer:

The punctuations used in coding are brackets, parenthesis, brace, and colons. The use of these punctuations is different. It adds information to the code and helps in designing the most appropriate code.
A descriptor presented within the parentheses is an optional part of the code description. Therefore, option b. is correct.
Reason for the correct statement:
Parenthesis ( ) is used for enclosing supplementary words or descriptors. These supplementary words are optional in the statement of disease and do not affect the code number to which it is assigned.
Hence, option b. is correct.
Reasons for the incorrect statements:
Option a. is given as, "A mandatory part of the code description."
Parenthesis encloses supplementary words and these words are optional, not compulsory. The compulsory part of a code description is written inside the italicized bracket.
Option c. is given as, "A previously deleted code description."
There is no punctuation sign to write a previously deleted code description.
Option d. is given as, "A manifestation."
Manifestation is identified and depicted in the form of notations, not punctuations.
Hence, options a. , c. , and d. are incorrect.
Parenthesis ( ) is used for enclosing descriptor words, and these words are optional and do not affect the code number to which they are assigned.

Answer:

In medical coding, the extra notation directs the reader towards identifying the manifestations or other conditions that are probable to be associated with the condition. Different types of notations used are NEC, NOS, other specified and unspecified, and see also conditions.
NOS means the physician didn't provide more details. Therefore, option b. is correct.
Reason for the correct statement:
NOS stands for "not otherwise specified" which means this notation is used if the physician did not provide any more details that are identified in any of the other available code descriptions.
Hence, option b. is correct.
Reasons for the incorrect statements:
Option a. is given as, "The hospital didn't provide more details."
The coder uses NOS during the medical coding, and medical coding is based on the information provided by the physician and not the hospital.
Option c. is given as, "The ICD-9-CM didn't provide more details."
The coder uses NOS during the medical coding, and medical coding is based on the information provided by the physician and not the ICD-9-CM.
Option d. is given as, "The patient didn't provide more details."
The patient can only provide information about the sign and symptoms, but the diagnosis is carried out by the physician, and the coding is done based on the notes prepared by the physician.
Hence, options a. , c. , and d. are incorrect.
NOS stands for "not otherwise specified" means the physician did not provide more details.
