When a "code first" note is present in the ICD-10-CM tabular list, it instructs the coder to sequence the underlying condition before the symptom or related condition. This indicates that the underlying condition is critical to the patient's diagnosis and that coding it first provides a clearer picture of the patient's health condition.

In this scenario, when the documentation reflects the presence of an underlying condition, it must be reported first according to the coding guidelines. This ensures that the primary health issue is identified correctly in the coding and billing process, impacting the patient's medical records and potentially influencing reimbursement.

The presence of a "code first" note emphasizes the importance of this underlying condition, and it mandates that coders prioritize its reporting. By doing so, it maintains compliance with coding standards, accurately reflects the clinical picture, and supports appropriate treatment pathways.
