In simple words: This code refers to a peptic ulcer in an unspecified location. It is not known whether the ulcer is acute or chronic, and it's not bleeding or perforated.

Peptic ulcer of unspecified site, unspecified as acute or chronic, without hemorrhage or perforation. This code includes gastroduodenal ulcers and peptic ulcers NOS.It excludes peptic ulcer of newborn (P78.82).

Example 1: A patient presents with abdominal pain and discomfort. Endoscopy reveals a peptic ulcer, but the location isn't clearly identified, and there are no signs of bleeding or perforation. The physician cannot determine whether it is acute or chronic at this time. K27.9 is appropriate., A patient with a history of dyspepsia undergoes an upper GI series showing an ulcer, but the exact site within the stomach or duodenum is not clearly visualized.There is no evidence of hemorrhage or perforation. The physician documents the ulcer as unspecified as acute or chronic. K27.9 is the appropriate code to use., A patient admitted for abdominal pain is found to have an ulcer, but further investigation is needed to determine the exact location, chronicity, and the presence of complications like hemorrhage or perforation. Initially, K27.9 can be used until more definitive information is available.

Documentation should include details of patient history, presenting symptoms (e.g., abdominal pain, nausea, vomiting), diagnostic findings from imaging or endoscopic procedures (e.g., location, size of the ulcer if known), and absence of hemorrhage and perforation.If the physician can determine whether the ulcer is acute or chronic, that should also be documented.

** It is important to distinguish K27.9 from other K27 codes that specify the presence of hemorrhage or perforation. If further investigation reveals the specific site, chronicity, or presence of complications, the code should be updated accordingly.
