Answer: Combination code guideline
Combination codes in ICD-10-CM allow a single code to classify two diagnoses, a diagnosis with an associated sign/symptom, or a diagnosis with an associated complication.
How should a coder handle a diagnosis documented as 'probable' or 'suspected' in an outpatient setting?
