Clinical Information

• Pneumoperitoneum

  a condition with trapped gas or air in the peritoneal cavity, usually secondary to perforation of the internal organs such as the lung and the gastrointestinal tract, or to recent surgery. pneumoperitoneum may be purposely introduced to aid radiological examination.

• Pneumoperitoneum, Artificial

  deliberate introduction of air into the peritoneal cavity.

• Mesenteric Cyst

  a rare intra-abdominal tumor in the mesentery. mesenteric cysts are usually benign and can be very large fluid-filled (2000 ml) lesions.

• Peritoneal Fibrosis

  disorder characterized by a wide range of structural changes in peritoneum, resulting from fibrogenic or inflammatory processes. peritoneal fibrosis is a common complication in patients receiving peritoneal dialysis and contributes to its gradual decrease in efficiency.

• Pneumoperitoneum

  free air within the peritoneal cavity.

K66.8 is grouped with Diagnostic Related Groups - MS-DRG Mapping

Diagnostic Related Groups (DRGs) are a classification system used to group together diagnosis codes for the purpose of reimbursement and healthcare management. DRGs are used to standardize the way hospitals and other providers are paid for inpatient services. In this system patients are grouped together based on their principal diagnosis in areas referred to as Major Diagnostic Categories (MDC). Once a patient is assigned a particular diagnostic category, providers receive a predetermined payment rate for the services rendered. This reimbursement rate is often fixed and is meant to cover the cost of care for that patient. Reimbursement is also affected by the relative weight of a diagnostic related group based on the severity of a patient's illness and the associated cost of care during hospitalization.

Diagnostic related groups encourage healthcare providers to focus on quality and efficiency in patient care while managing costs effectively. The diagnosis code is present in the following groups for version MS-DRG V41.0 applicable from 10/01/2023 through 09/30/2024.

The relative weight of a diagnostic related group determines the reimbursement rate based on the severity of a patient's illness and the associated cost of care during hospitalization.

Convert K66.8 to ICD-9-CM

• ICD-9-CM Code: 568.89 - Peritoneal disorder NEC
  Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.

Patient Education

Peritoneal Disorders

Your peritoneum is the tissue that lines your abdominal wall and covers most of the organs in your abdomen. A liquid, peritoneal fluid, lubricates the surface of this tissue.

Disorders of the peritoneum are not common. They include:

• Peritonitis - an inflammation of the peritoneum
• Cancer
• Complications from peritoneal dialysis

Your doctor may use imaging tests or lab tests to analyze the peritoneal fluid to diagnose the problem. Treatment of peritoneal disorders depends on the cause.
