What does the instruction "See" imply in coding?

The instruction "See" in ICD-10-CM coding suggests that there is related information or additional codes that may be pertinent for the diagnosis or procedure being coded. This instruction indicates that coders must consult another code or section of the coding manual for the proper coding. It indicates that further investigation is necessary to ensure accurate coding.

In this context, a mandatory follow-up coding implies that the coder is required to look up the term or code referenced by "See" to find additional codes that may be applicable or that need to be included for an accurate representation of the patient's condition or treatment. This ensures completeness and accuracy in coding practices, which is important for reimbursement and statistical purposes.

Other interpretations such as substitution of codes or simply reviewing previous codes do not capture the necessity to follow up with additional coding that the "See" instruction specifically mandates. Similarly, the idea that no further coding is needed contradicts the purpose of the "See" instruction, which directs the coder to seek out further detail, thereby underscoring its importance in the coding process.
