  • NDC (National Drug Code, assigned by the FDA to identify specific drugs)
  • ICD-10-CM (International Classification of Diseases, 10th Revision, Clinical Modification, assigned by WHO, World Health Organization to classify diagnoses, used in all places of service)
  • HCPCS (Healthcare Common Procedure Coding System assigned by CMS to identify products or procedures)

The NDC Codes below are assigned to “Omegaven®” (also known as fish oil triglycerides injectable emulsion), a human prescription drug labeled by “Fresenius Kabi USA, LLC”.

NDC Description Concentration Unit of Use
63323-205-21 50 mL single-dose glass bottle 5g/50 mL
(0.1 grams per mL)
63323-205-31 100 mL single-dose glass bottle 10g/100 mL
(0.1 grams per mL)

For reimbursement purposes, some payers may require the Healthcare Provider to include NDCs on the claim form. For claims-reporting purposes, some payers may also require HCPs to convert the 10-digit NDC to an 11-digit NDC by adding a “0” (zero) where appropriate to create a 5-4-2 configuration. The zero is added in front of the second segment of numbers when the 10-digit format is the 5-3-2 configuration.

The following is an example of converting a 10-digit NDC to an 11-digit NDC for Omegaven®: NDC 63323-205-21 would become NDC 63323-0205-21

NDC – National Drug Code (The NDC, or National Drug Code, is a unique 10-digit or 11—digit, 3 segment number, and a universal product identifier for human drugs in the United States.

The 3 segments of the NDC identify:

  • The labeler (Segment #1)
  • The product (Segment #2)
  • The commercial package sizes (Segment #3)

ICD-10-CM – International Classification of Diseases, 10th Revision, Clinical Modification

Daily parenteral nutrition is considered reasonable and necessary for a patient with severe pathology of the alimentary tract which does not allow absorption of sufficient nutrients to maintain weight and strength commensurate with the patient’s general condition.

Below is a table of common diagnosis codes that may be covered by an insurance company. Patient specific diagnosis should be validated with the patient’s insurance company. This list is not all inclusive, but only a small list of possibilities:

Description Diagnosis Code
Malabsorption due to intolerance, not elsewhere classified K90.48
Complete intestinal obstruction, unspecified as to cause K56.601
Acute Infarction of intestine, part and extent unspecified K55.069
Postsurgical malabsorption, not elsewhere classified K91.2
Acquired absence of other specified parts of digestive tract Z90.49
Fistula of Stomach and duodenum K31.6

Gastrointestinal transplantation Z94.82
Irritable Bowel Syndrome K58.1

Payer Types

Medicare – a federal system of health insurance for people over 65 years of age and for certain younger people with disabilities. Medicare coverage is categorized into four groups:

Part A – Hospital Inpatient
Part B – Durable Medical Equipment, prosthetics/orthotics and Enteral/Parenteral Nutrition
Part C – Medicare Advantage plans
Part D – Prescription Drug Coverage

Omegaven® is considered a parenteral nutrition lipid emulsion and therefore covered by Part B, Medicare.  Medicare coverage is administered by commercial insurance companies that contract with Medicare.  Commercial insurers that have been awarded the Part B contracts are called DME-MACs (Durable Medical Equipment Medicare Administrative Contractors).

Below is a table that provides the names of the commercial insurers that have been awarded the DME-MAC contracts for 2020 by state:

2020 Medicare Administrative Carrier Contracts for DME-MAC Coverage

Jurisdiction States Covered Medicare Administrative Carrier (MAC)
Jurisdiction A CT DE DC MD ME ML NH NJ NY PA RI VT Noridian Healthcare Solutions
Jurisdiction B IL ID KY MI MN OH WI CGS, A Celerian Group Company
Jurisdiction C AL AK CO FL GA LA MS NM NC OK PR SC TN TX U.S. VIRGIN ISLANDS VA WV CGS, A Celerian Group Company

Medicare Advantage – Medicare beneficiaries are offered Medicare coverage via commercial insurance companies that at a minimum Medicare coverage, but often enhanced benefits.  These plans are also referred to as Part C.

Medicaid – A federal/state system of health insurance for those patients requiring financial assistance.

Commercial – Health insurance that is typically offered via an employer or purchased by the patient directly from a for-profit insurance company.

Coverage Policy


The following is a brief summary of Medicare’s coverage of parenteral nutrition.  Medicare’s coverage policy is particularly important due to other insurance types (Medicare Advantage, Medicaid and Commercial) often follow Medicare’s coverage policy.

Medicare’s coverage of Parenteral Nutrition is standardized by implementation of a National Coverage Determination (NCD) for Enteral and Parenteral Nutritional Therapy (180.2). This means that all Medicare patients across the U.S. have the same benefits and are held by the same coverage criteria.

Parenteral Nutrition Coverage Criteria:

Parenteral Nutrition Therapy is considered reasonable and necessary for a patient with severe pathology of the alimentary tract which does not allow absorption of sufficient nutrients to maintain weight and strength commensurate with the patient’s general condition.  Coverage of nutritional therapy as a Part B benefit is provided under the prosthetic device benefit provision, which requires that the patient must have a permanently inoperative internal body organ or function thereof. Therefore, parenteral nutritional therapy is normally not covered in situations involving temporary impairments.

Parenteral nutrition therapy claims must be as a result of a physician’s written order or prescription to prove medical necessity. DME MACs will only reimburse for 30-day supplies at a time.

To qualify for coverage of Parenteral Nutrition, the following requirements must be met:

  • To qualify for Medicare coverage of Parenteral Nutrition the patient is required to have severe pathology of the alimentary tract that does not allow absorption of sufficient nutrients to maintain weight and strength commensurate with the patient’s general condition. PN must be administered 7 days per week and PN is required for a minimum of 90 days.
  • A total caloric daily intake (parenteral, enteral, and oral) of 20-35 cal/kg/day is considered sufficient to achieve or maintain appropriate body weight. The ordering physician must document in the medical record the medical necessity for a caloric intake outside this range in an individual patient.
  • The ordering physician must document the medical necessity for protein orders outside of the range of 0.8-1.5 gm/kg/day, dextrose concentration less than 10%, or lipid use greater than 1500 grams (150 units of service of code B4185) per month.
  • Prescription/Orders – Medicare requires a DME Information Form (DIF) be completed, signed, and dated by the supplier, must be kept on file by the supplier and made available upon request. The DIF for parenteral nutrition is CMS Form 10126. The initial claim must include an electronic copy of the DIF. CMS 10126 – ENTERAL AND PARENTERAL NUTRITION
  • Medical Records – Physician prescription documenting continued need/use if applicable. The patient’s diagnosis must be severe pathology of the alimentary tract, which does not allow absorption of sufficient nutrients to maintain weight and strength commensurate with the patient’s general condition.
  • Correct Coding – HCPCS codes correct to the product administered, ICD-10 diagnosis codes to document qualifying diagnosis
  • Proof of Delivery – Signed delivery slip or proof of delivery via shipping

Prior Authorization

Medicare requires precertification/prior authorization for Parenteral Nutrition. A precertification number should be placed in Box 23 of the DMS 1500 claim form.

Most insurance plans require a Prior Authorization be submitted prior to provision of Omegaven® to a patient.  Please contact the patient’s insurance company to identify required forms and how/where to submit the Prior Authorization.

Product Coding

HCPCS codes (Healthcare Common Procedure Coding System) identify a specific product.  Below is a table that demonstrates what codes have been suggested by payers.  Provision of these codes is not a guarantee that the codes will be accepted by every payer.  Check with each patient’s insurance company for coverage of these codes.

Omegaven®(fish oil triglycerides) Injectable emulsion

NDC Fill Volume Description Concentration HCPCS Code Options – Lipids
63323-205-21 50 mL  Single Dose Glass Bottle 5 grams per 50 mL
(0.1 grams per mL)
B4187-Omegaven®, 10 grams lipids
B4185 – Parenteral Nutrition Solution, Not Otherwise Specified, 10 Grams Lipids
63323-205-31 100 mL Single Dose Glass Bottle 10 grams per 100 mL
(0.1 grams per mL)
B4187-Omegaven®, 10 grams lipids
B4185 – Parenteral Nutrition Solution, Not Otherwise Specified, 10 Grams Lipids

HCPCS Code B4185 should be billed with a billing unit of “1” for each 10 Grams. For the 50mL the billing unit would be .5 units per day.  In a 30-day month it would be 15 billing units administered at 5 grams per day.

If an IV Pole and infusion pump are also used, the coding used could be:

Equipment HCPCS Code
IV Pole E0776
Parenteral Nutrition Infusion Pump, Stationary B9006
Parenteral Nutrition Supply Kit; Premix, Per Day B4220
Parenteral Nutrition Administration Kit, Per Day B4224

If the coverage requirements for parenteral nutrition are met, one supply kit (B4220) and one administration kit (B4224) will be covered for each day that parenteral nutrition is administered. For example, June has 30 days in it, therefore the billing unit when billing for the month of June should be “30”. This number should be in box 24G on the CMS 1500 claim form.


A Modifier that apply to the IV Pole or ambulatory infusion pump is “RR” – Rental. Append to appropriate code when billing rental items (inexpensive, capped rental, items that require servicing. Modifiers are to be placed in Box 24D of the CMS-1500. Up to 4 modifiers can be attached to each HCPCS code.

Place of Service Codes

Place of Service Codes tell the insurance company where Omegaven®is administered. The Place of Service code should be placed in Box 24B of the CMS-1500. Coverage of Parenteral Nutrition is based on the patient’s place of service. Products are either paid for using HCPCS codes and payment amounts on the payer’s fee schedule or on a “Per Diem” rate. Per Diem means the facility is paid a daily or monthly amount to provide all services to the patient, which includes their daily nutritional needs. Per Diem rates apply to hospital inpatient or Skilled Nursing Facilities.

Place of Service Code Place of Service Name Place of

31 Skilled Nursing Facility A facility that provides inpatient skilled nursing to patients but does not provide level of care available in a hospital Considered a “Per Diem” situation. Skilled facilities are paid a fixed rate that includes parenteral nutrition

Performing a Benefit Verification

Coverage criteria for each individual patient should be validated by contacting the patient’s insurance company directly.  This process is called a “Benefit Verification”. The phone number for the Benefits or Customer Service department at the patient’s insurance company should be on the back side of the patient’s insurance card.

Some of the information to be gathered from the insurance company during a Benefit Verification can include:
