ICD-10-CM Code K66.8
Other specified disorders of peritoneum

Billable Code
Billable codes are sufficient justification for admission to an acute care hospital when used a principal diagnosis.
| ICD-10 from 2011 - 2016

K66.8 is a billable ICD code used to specify a diagnosis of other specified disorders of peritoneum. A 'billable code' is detailed enough to be used to specify a medical diagnosis.

The ICD code K668 is used to code Pneumoperitoneum

Pneumoperitoneum is pneumatosis (abnormal presence of air or other gas) in the peritoneal cavity, a potential space within the abdominal cavity. When present, it can often be seen on radiography, but small amounts are often missed, and CT scan is nowadays regarded as a criterion standard in the assessment of a pneumoperitoneum. CT can visualize quantities as small as 5 cm³ of air or gas. The most common cause is a perforated abdominal viscus, generally a perforated peptic ulcer, although any part of the bowel may perforate from a benign ulcer, tumor or abdominal trauma. A perforated appendix seldom causes a pneumoperitoneum.
