Final Answer:
ICD-10-CM codes should be between 3 and 7 characters in length. Thus, the correct answer is option c) 7.
Step-by-step explanation:
ICD-10-CM codes should be between 3 and 7 characters in length. These alphanumeric codes are used to classify and report medical diagnoses and procedures. The range of 3 to 7 characters allows for flexibility in coding different conditions while maintaining a standardized format.
In the ICD-10-CM coding system, codes can range from three characters, representing a broad category, to seven characters, providing a more detailed and specific code. The additional characters beyond the first three further specify the location, severity, and other relevant details of the medical condition or procedure. This system aids in accurate billing, epidemiological studies, and overall healthcare management.
Thus, the correct answer is option c) 7.
