DESCRIPTIONParenteral nutritional support (PEN), also known as parenteral hyperalimentation, is used for patients with medical conditions that impair gastrointestinal absorption to a degree incompatible with life. It is also used for variable periods of time to bolster the nutritional status of severely malnourished patients with medical or surgical conditions. PEN involves percutaneous transvenous implantation of a central venous catheter into the vena cava or right atrium. A nutritionally adequate hypertonic solution consisting of glucose (sugar), amino acids (protein), electrolytes (sodium, potassium), vitamins and minerals, and sometimes fats is administered daily. An infusion pump is generally used to assure a steady flow of the solution either on a continuous (24-hour) or intermittent schedule. If intermittent, a heparin lock device and diluted heparin are used to prevent clotting inside the catheter.
Enteral nutrition support (EN) is used for patients with a functioning intestinal tract, but with disorders of the pharynx, esophagus or stomach that prevent nutrients from reaching the absorbing surfaces in the small intestine. The patient is at risk of severe malnutrition. EN involves administering non-sterile liquids directly into the gastrointestinal tract through nasogastric, gastrostomy, or jejunostomy tubes. An infusion pump may be used to assist the flow of liquids. Feedings may be either intermittent or continuous (infused 24 hours/day).
POLICYParticipating providers are required to follow the American Dietetic Association Medical Nutrition Therapy Protocols for Parenteral and Enteral Feeding Support.
Parenteral feeding support (PEN) in the home is considered medically necessary in the treatment of inanition associated with conditions resulting in impaired intestinal absorption, including the following conditions, but not limited to, any of the conditions listed in the "Code Reference" section.
The following criteria must be met prior to the initial implementation of parenteral feeding support (PEN):
Enteral feeding support (EN) in the home is considered medically necessary under the following conditions:
If 25% of estimated calories needed per day or less are being administered by PEN or EN, they are considered supplemental and benefits will be denied as not medically necessary.
Benefits will not be provided for nutritional substances when used:
Blenderized baby food and regular shelf food used with an enteral system are not eligible for benefits.
Nutrients and their method of administration for both PEN and EN must be specifically ordered by a physician.
Approved PEN or EN services (those that require a physician's prescription) may include, but are not limited to, the following:
POLICY GUIDELINESGlobal allowances for PEN and EN feeding support in the home include nursing services, cost of supplies, clinical pharmacy service, dietitian monitoring, supply delivery and administrative overhead.
Benefits may be provided for placement of central venous catheters and nasogastric, nasojejunostomy, gastrostomy or jejunostomy feeding tubes when policy guidelines have been met for PEN or EN.
The total cost of renting equipment should not exceed the purchase cost of the equipment.
The coverage guidelines outlined in the Medical Policy Manual should not be used in lieu of the Member's specific benefit plan language.
