Symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified

Covers symptoms, signs, and abnormal clinical/laboratory findings that are not otherwise classified to a more definitive diagnosis elsewhere.

Key coding points

• •Codes from this chapter are appropriate when a definitive diagnosis has not yet been established, or when the sign/symptom is being reported on its own because no related definitive diagnosis was confirmed for that encounter.
• •If a definitive diagnosis is established, it should generally be coded instead of, or in addition to, the associated symptom, depending on payer and documentation guidance.
