Approximate Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

• Acquired short bowel syndrome
• Blind loop syndrome
• Fatty stool
• Fatty stool
• Malnutrition
• Malnutrition following gastrointestinal surgery
• Post-gastrointestinal tract surgery malnutrition
• Postoperative blind loop syndrome
• Postprocedural intestinal steatorrhea
• Postprocedural steatorrhea
• Post-surgical malabsorption
• Post-surgical malabsorption
• Protein losing enteropathy due to and following cardiac procedure
• Protein-losing enteropathy
• Short bowel syndrome

Clinical Information

• Short Bowel Syndrome

  a malabsorption syndrome resulting from extensive operative resection of the small intestine, the absorptive region of the gastrointestinal tract.

• Child Nutrition Disorders

  disorders caused by nutritional imbalance, either overnutrition or undernutrition, occurring in children ages 2 to 12 years.

• Fetal Nutrition Disorders

  disorders caused by nutritional imbalance, either overnutrition or undernutrition, in the fetus in utero.

• Infant Nutrition Disorders

  disorders caused by nutritional imbalance, either overnutrition or undernutrition, occurring in infants ages 1 month to 24 months.

• Malnutrition

  an imbalanced nutritional status resulting from insufficient intake of nutrients to meet normal physiological requirement.

• Protein-Energy Malnutrition

  the lack of sufficient energy or protein to meet the body's metabolic demands, as a result of either an inadequate dietary intake of protein, intake of poor quality dietary protein, increased demands due to disease, or increased nutrient losses.

• Severe Acute Malnutrition

  acute form of malnutrition which usually affects children, characterized by a very low weight for height (below -3z scores of the median world health organization standards), visible severe wasting, or occurrence of nutritional edema. it can be a direct or indirect cause of fatality in children suffering from diarrhea and pneumonia. do not confuse with starvation, a condition in which the body is not getting enough food, usually for extended periods of time.

• Blind Loop Syndrome

  a malabsorption syndrome that is associated with a blind loop in the upper small intestine that is characterized by the lack of peristaltic movement, stasis of intestinal contents, and the overgrowth of bacteria. such bacterial overgrowth interferes with bile salts action, fatty acids processing, microvilli integrity, and the absorption of nutrients such as vitamin b12 and folic acid.

• Fetus

  the unborn young of a viviparous mammal, in the postembryonic period, after the major structures have been outlined. in humans, the unborn young from the end of the eighth week after conception until birth, as distinguished from the earlier embryo, mammalian.

• Short Bowel Syndrome

  malabsorption that results from the removal of a large segment of the small intestine or, less frequently, from the complete dysfunction of a large portion of the small intestine. signs and symptoms include diarrhea, steatorrhea, and weight loss.

K91.2 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.

MS-DRG	MS-DRG Title	MCD	Relative Weight
391	ESOPHAGITIS, GASTROENTERITIS AND MISCELLANEOUS DIGESTIVE DISORDERS WITH MCC	06	1.2757
392	ESOPHAGITIS, GASTROENTERITIS AND MISCELLANEOUS DIGESTIVE DISORDERS WITHOUT MCC	06	0.7856

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.

Patient Education

After Surgery

After any operation, you'll have some side effects. There is usually some pain with surgery. There may also be swelling and soreness around the area that the surgeon cut. Your surgeon can tell you which side effects to expect.

There can also be complications. These are unplanned events linked to the operation. Some complications are infection, too much bleeding, reaction to anesthesia, or accidental injury. Some people have a greater risk of complications because of other medical conditions.

Your surgeon can tell you how you might feel and what you will be able to do - or not do - the first few days, weeks, or months after surgery. Some other questions to ask are:

• How long you will be in the hospital
• What kind of supplies, equipment, and help you might need when you go home
• When you can go back to work
• When it is ok to start exercising again
• Are they any other restrictions in your activities

Following your surgeon's advice can help you recover as soon as possible.

Malabsorption Syndromes

Your small intestine does most of the digesting of the foods you eat. If you have a malabsorption syndrome, your small intestine cannot absorb nutrients from foods.

Causes of malabsorption syndromes include:

• Celiac disease
• Lactose intolerance
• Short bowel syndrome. This happens after surgery to remove half or more of the small intestine. You might need the surgery if you have a problem with the small intestine from a disease, injury, or birth defect.
• Whipple disease, a rare bacterial infection
• Genetic diseases
• Certain medicines

Symptoms of different malabsorption syndromes can vary. They often include chronic diarrhea, abnormal stools, weight loss, and gas. Your doctor may use lab, imaging, or other tests to make a diagnosis.

Treatment of malabsorption syndromes depends on the cause.
