Enteral and Parenteral Nutrition

Coverage and Documentation

Enteral Nutrition

Accessories

More than three nasogastric tubes (B4081, B4082, and B4083) or one gastrostomy/jejunostomy tube (B4087 or B4088) every three months is not medically necessary.

Billing

If two enteral nutrition products, which are described by same HCPCS code, are being provided at same time, bill on a single claim line with units of service reflecting total calories of both nutrients.

If coverage requirements for enteral nutrition are met, medically necessary nutrients, administration supplies and equipment are covered.

Formulas

Enteral formulas consisting of semi-synthetic intact protein/protein isolates (B4150 or B4152) are appropriate for a majority of beneficiaries requiring enteral nutrition.

For special enteral formulas (B4149, B4153, B4154, B4155, B4157, B4161, and B4162) medical necessity must be justified for each beneficiary as to why this special formula is needed versus semi-synthetic enteral formula.

Pumps

If an enteral pump (B9002) is ordered, there must be sufficient documentation in the beneficiary's medical record to justify its use. Examples of statements showing medical necessity would be "gravity feeding is not satisfactory due to reflux"; "aspiration"; "severe diarrhea"; "dumping syndrome"; "administration rate less than 100ml/hr"; "blood glucose fluctuations"; "circulatory overload; or "gastrostomy/jejunostomy tube used for feeding". If medical necessity of the pump is not documented, the pump will be denied.

Supply Kit Fee/Allowance

The enteral feeding supply kit is a daily feeding supply fee/allowance, and includes all supplies, other than the feeding tube and nutrients, required for the administration of enteral nutrients to the beneficiary for one day. The supply needs will vary between beneficiaries.

Enteral feeding supply kits (B4034, B4035, B4036, and B4148) are specific to the route of administration and submission of a claim for more than one type of kit code delivered on same date or provided on an ongoing basis will be denied as not medically necessary.

Parenteral Nutrition

Pumps

Only one infusion pump (B9004, B9006) is covered for beneficiaries in whom parenteral nutrition is required.

Supply Kit Fee/Allowance

Parenteral supply allowances (B4220, B4222 and B4224) allow only one supply kit and one administration kit for each day parenteral nutrition is administered. This a daily supply fee rather than a specifically defined "kit" and include all supplies required for the administration of parenteral nutrition to the beneficiary for one day.

Tips

Billing

It is possible for Medicare to have records on file that contain different information than in supplier records. This could result in payments that are not in an amount expected by the supplier. It is imperative that suppliers keep current records on file to properly reflect current provision of nutrition. Denials must follow the appeals process.
