Coverage criteria for enteral nutrition

General medical necessity criteria

Covered when ALL of the following are met:

CMN completion and signatures: Completed Certificate of Medical Necessity (CMN) with ordering clinician (physician, physician assistant, or nurse practitioner) completion of the clinical information section and signature, and supplier attestation that items supplied match the order.

Chunks 2,11

Clinical justification: Documentation demonstrates either a non-function or disease of the structures that normally permit food to reach the small bowel or disease of the small bowel impairing digestion/absorption (anatomic condition or motility disorder), OR inadequate protein/caloric intake from regular, liquefied, or pureed foods.

Chunk 0

Pediatric consultation when under 21: For members under 21 years, documentation of consultation with a registered dietitian or licensed nutritionist within the last 12 months is required (EPSDT or Alaska WIC Nutrition Program consultation acceptable).

Chunk 0

Temporary condition assessment: If enteral needs are due to a temporary condition expected to resolve within 3 months, the CMN must document this assessment (Question 5).

Chunk 0

Quantity limits and documentation: Requested quantities must not exceed Alaska Medicaid maximum allowable quantities per the current DMEPOS fee schedule; requests exceeding those quantities must include supporting medical records demonstrating medical necessity.

Chunk 16

Prescriptions that only change the brand of an enteral formula but remain under the same HCPCS code and quantity as a previously authorized prescription do not require an amendment to the existing service authorization. Providers should forward all other changes or requests for additional services/items to the Alaska Medicaid Fiscal Agent Service Authorization department as instructed on the form.

HCPCS / Procedure codes and fee-schedule quantities

Requested HCPCS / Procedure Codesmixed

HCPCS

Procedure/Drug/HCPCS codes to be entered for requested items (specific codes not listed on form)

Allowed quantities per DMEPOS fee schedule

When to include documentationSupporting medical records must accompany any request that exceeds the Medicaid maximum allowable quantities.

Where limits are definedMaximum allowable quantities are defined on the current Alaska Medicaid DMEPOS fee schedule.

Form fieldThe CMN requests number of monthly refills (1–11 months) to specify recurring quantity amounts.

Service authorization, documentation, and signature requirements

Prior Authorization

Service authorization and retroactive approval rules

Prior authorization is required for enteral nutrition services and supplies. Requests that may be approved retroactively include: an initial request for a member discharging from an inpatient status; a revised prescription for a formula categorized under a different HCPCS code than previously authorized (for example, changing from B4159 to B4161); or a revised prescription with an increase in caloric intake. Retroactive approvals will reflect the dispense date. All other requests (such as transferring providers, annual renewals, or untimely submitted dispensed requests) will be approved with a start date no earlier than the request review date or the expiration date of the existing authorization being renewed, whichever is later.

Retroactive approval scenarios: initial discharge from inpatient, HCPCS code change, increased calories
Other requests: start date = max(review date, existing authorization expiration)

Documentation Required

Pump necessity requirement

When a pump is requested instead of syringe or gravity feeding, the ordering clinician must provide documentation demonstrating medical necessity for the pump over syringe/gravity methods. Medical records should clearly explain why alternative methods are inappropriate or contraindicated for this member.

Route of Administration options include Syringe, Gravity, Pump, Oral
If Pump is requested, medical records must support necessity of pump over syringe/gravity

Documentation Required

Required documentation for requests exceeding maximum quantities

Supporting medical records must accompany any requests for quantities exceeding Alaska Medicaid maximum allowable quantities. Documentation should demonstrate medical necessity and justify the requested quantity relative to the member's clinical condition.

Submit documentation when requested quantities exceed Alaska Medicaid DMEPOS fee schedule maximums
Records should include clinical rationale and relevant assessment data

Documentation Required

Signatures and attestations

The ordering physician, physician assistant, or nurse practitioner must complete the clinical section of the request form, attest to medical necessity, sign and date the form. False statements may result in civil or criminal penalties.

Ordering clinician must complete clinical section and sign attestation
Attestation affirms information is true, accurate, and complete

Denial Risk

Service Authorization ID and potential denial marking

The fiscal agent will record a Service Authorization ID and may mark the request as approved, approved as modified, or denied. Providers should monitor the authorization decision and adhere to any modified terms.

AK Medicaid Fiscal Agent will assign Service Authorization ID
Authorization statuses: Approved as requested, Approved as modified, Denied

Clinical and equipment-route justification

DME route/equipment criteria

Equipment and route selection must be clinically justified and documented.

Route of administration: Requested route(s) of administration (syringe, gravity, pump, oral) must be specified on the CMN.

Chunk 1,11

Pump-specific justification: If pump administration is requested, medical records must specifically support the necessity of a pump over syringe or gravity methods.

Chunk 1

Documentation for non-standard equipment or quantities: When requesting equipment, routes, or quantities that exceed Alaska Medicaid fee schedule allowances or that deviate from common practice, include supporting clinical documentation justifying selection and medical necessity.

Chunk 16

When to attach supporting clinical documentation

Documentation Required

Attach supporting clinical records for pump requests and quantity overrides

When requesting a pump or higher-than-allowed quantities, attach the supporting clinical documentation to justify pump use and the need for quantities above Alaska Medicaid limits.

Documentation must specifically justify pump necessity over syringe/gravity.
Requests for quantities exceeding Alaska Medicaid maximum allowable quantities must include supporting medical records per the DMEPOS fee schedule.

Signatures/attestation on replacementOrdering clinician (physician, PA, or NP) must complete clinical information and attest to medical necessity; supplier must attest items supplied match order — applies to all equipment requests.

Definitions and clinical context

Enteral nutrition need

DefinitionEnteral nutrition is indicated when anatomy or motility prevents adequate oral intake or when small bowel disease impairs digestion/absorption, requiring formula delivered enterally (tube or oral).

Clinical scenarios - anatomic or motility disordersConditions demonstrating non-function or disease of structures that normally permit food to reach the small bowel (may be anatomic or motility disorder).

Clinical scenarios - impaired digestion/absorptionSmall bowel disease that impairs digestion and absorption of an oral diet, necessitating enteral support.

Pediatric considerationFor members under 21 years, consultation with a registered dietitian or licensed nutritionist within the last 12 months is required (EPSDT or WIC acceptable).

Background on enteral nutrition

Enteral nutrition is used when oral intake is inadequate or when anatomic or functional disorders prevent food from reaching or being absorbed in the small bowel. The Certificate of Medical Necessity (CMN) documents the clinical indication, calorie/protein needs, and whether the need is temporary, and it collects information such as diagnosis codes and whether pediatric nutrition consultation has occurred. This information supports coverage decisions and any authorization requests for enteral formulas or delivery equipment.

Non-covered or administrative-notes

Administrative changes that only alter the brand of formula, but leave the HCPCS code and quantity unchanged, are considered administrative and do not require a service authorization amendment. All other modifications to an approved enteral authorization or requests for additional items must be submitted to the Alaska Medicaid Fiscal Agent Service Authorization department.
