Neoplasm of unspecified nature of digestive system

This code signifies the presence of a growth or mass within any part of the digestive system (e.g., esophagus, stomach, intestines, liver, pancreas) where the specific pathological nature (benign, malignant, or uncertain) has not yet been determined or documented. It indicates an abnormal tissue proliferation without a definitive diagnosis of its biological behavior.

Use this code when diagnostic workup for a digestive system mass is ongoing, and the pathology report is pending or inconclusive regarding malignancy. It is appropriate for initial encounters where a lesion is identified but its specific type is unknown, such as after an endoscopy revealing a polyp or an imaging study showing a liver mass.

• This is a temporary code; strive for a more specific diagnosis once pathology results are available.
• Do not use if the documentation clearly states benign, malignant, or uncertain behavior; instead, select the appropriate code from categories 211.x, 150-159.x, or 235.x.
• Always query the provider for definitive pathology results or further clarification if the documentation is ambiguous.
