Which type of note is found below the infectious disease code in the ICD-10-CM tabular list, indicating the need for additional coding?

The note type indicating the need for additional coding in the ICD-10-CM tabular list is "Use additional code." This note prompts coders to include one or more additional codes to fully capture the clinical picture of the patient's condition. It emphasizes that a single code does not provide a comprehensive view of the diagnosis and that further details are necessary for accurate coding and billing purposes.

In practice, when a coder encounters this note, it is essential to locate and apply the specified additional code(s) that reflect complications or coexisting conditions that are relevant to the primary diagnosis. This ensures that records are complete and reflects the full extent of the patient's illness.

Understanding this coding instruction is critical as it helps in avoiding undercoding, which could result in the loss of potential reimbursement and inadequate representation of a patient's health condition in their medical records. Other note types serve different purposes, such as directing coders to alternative codes or additional information, but do not specifically indicate the need for supplementary codes like this one does.
