Ground Ambulance Procedure code A0425, A0427, A0428, A0433

Bill Type Codes for Ambulance Service (Ground Ambulance)

Contractors may specify Bill Types to help providers identify those Bill Types typically used to report this service. Absence of a Bill Type does not guarantee that the policy does not apply to that Bill Type. Complete absence of all Bill Types indicates that coverage is not influenced by Bill Type and the policy should be assumed to apply equally to all claims.

11x Hospital Inpatient (Including Medicare Part A)
12x Hospital Inpatient (Medicare Part B only)
13x Hospital Outpatient
22x Skilled Nursing - Inpatient (Medicare Part B only)
23x Skilled Nursing - Outpatient
83x Ambulatory Surgery Center
85x Critical Access Hospital

Revenue Codes

Contractors may specify Revenue Codes to help providers identify those Revenue Codes typically used to report this service. In most instances Revenue Codes are purely advisory; unless specified in the policy services reported under other Revenue Codes are equally subject to this coverage determination. Complete absence of all Revenue Codes indicates that coverage is not influenced by Revenue Code and the policy should be assumed to apply equally to all Revenue Codes.

Note: The contractor has identified the Bill Type and Revenue Codes applicable for use with the CPT/HCPCS codes included in this LCD. Providers are reminded that not all CPT/HCPCS codes listed can be billed with all Bill Type and/or Revenue Codes listed. CPT/HCPCS codes are required to be billed with specific Bill Type and Revenue Codes. Providers are encouraged to refer to the CMS Internet-Only Manual (IOM), Publication 100-04, Claims Processing Manual, for further guidance.

ICD-9 Codes that Support Medical Necessity

Group 1 Paragraph : Note: Providers should continue to submit ICD-9-CM diagnosis codes without decimals on their claim forms and electronic claims.

Medical necessity and coverage of ambulance services are not based solely on the presence of a specific diagnosis. Medicare payment for ambulance transportation may be made only for those patients whose condition at the time of transport is such that ambulance transportation is necessary. For example, it is insufficient that a patient merely has a diagnosis such as pneumonia, stroke or fracture to justify ambulance transportation. In each of those instances, the condition of the patient must be such that transportation by any other means is medically contraindicated. In the case of ambulance transportation, the condition necessitating transportation is often that an accident or injury has occurred giving rise to a clinical suspicion that a specific condition exists (for instance, fractures may be strongly suspected based on clinical examination and history of a specific injury).

It is the provider’s responsibility to supply the contractor with information describing the condition of the patient that necessitated ambulance transportation. Medicare recognizes limitations of usual ambulance personnel for establishing a diagnosis and recognizes, therefore, that diagnosis coding of a patient’s condition using ICD-9-CM codes when reporting ambulance services may be less specific than for services reported by other professional providers. Providers who submit diagnosis codes should choose the code that best describes the patient’s condition at the time of transport. As a reminder to providers of ambulance services, “rule out” or “suspected” diagnoses should not be reported using specific codes. In such instances where a diagnosis is not confirmed, it is more correct to use a symptom, finding or injury code.

Reporting ambulance services using a code from the list below certifies to Medicare that the ambulance provider believes the code description reasonably reflects the condition of the patient at the time of transport and that the patient’s condition was consistent with the requirements of the Medicare ambulance transportation benefit.

The contractor recognizes that ambulance suppliers are currently not required to submit diagnosis codes on their claims if filing on a 1500 claim form or utilizing an electronic version other than the 5010 version of the 837P, though their doing so facilitates timely claim adjudication. The CPT/HCPCS codes included in this LCD will be subjected to “procedure to diagnosis” editing. Claims without a diagnosis code from below will be adjudicated manually utilizing the information contained in the claim’s narrative field and/or medical records (the trip report and any other records supplied to Medicare by the provider upon our request). Ambulance suppliers utilizing the 5010 version of the 837P are required to submit diagnosis code(s).

Due to the large number of possible covered diagnosis codes, the Contractor is not providing a comprehensive list of covered diagnosis codes for HCPCS codes A0425, A0426, A0427, A0428, A0429, A0433 and A0434.

All ambulance transports require dual diagnosis codes as described below.

Providers should report the most appropriate ICD-9-CM code that adequately describes the patient's medical condition (for example: stroke, coma, trauma, etc.) at the time of transport as the primary diagnosis. In addition, a secondary diagnosis, from the list below, must be reported.

Additionally, the KX modifier must be reported on the claim for the service to be considered for coverage. Reporting of the KX modifier is an attestation from the provider that the services are reasonable and necessary and that there is documentation of medical necessity in the patient's record. The KX modifier should not be reported if the patient's condition does not require an ambul

Group 1 Codes


Note: Use code V46.11 to denote ventilator dependency transport ONLY.

Note: Use code V46.9 to denote the need for continuous IV fluids, 'active airway management' or the need for multiple machine devices.

Note: Use code V49.87 to denote patient safety: danger to self and others - monitoring other and unspecified reactive psychosis.

Note: Use code V71.9 to denote the need for continuous clinical assessment throughout the transport.
ICD-9 Codes that DO NOT Support Medical Necessity
Note: V68.61 should be reported for those patients who were transported by ambulance but did NOT require the services of an ambulance crew.

CMS Supplied National ZIP Code File and National Ambulance Fee Schedule File

CMS will provide each contractor with two files: a national ZIP Code file and a national Ambulance FS file.

A. The national ZIP5 Code file is a file of 5-digit USPS ZIP Codes that will map each ZIP Code to the appropriate FS locality. Every 2 months, CMS obtains an updated listing of ZIP Codes from the USPS. On the basis of the updated USPS file, CMS updates the Medicare ZIP Code file and makes it available to contractors.

The following is a record layout of the ZIP5 file effective January 1, 2009


Field Name           Position         Format         COBOL Description

State                 1-2               X(02)        Alpha State Code

ZIP Code             3-7          X(05)                 Postal ZIP Code

Carrier                     8-12          X(05)           Medicare Part B Carrier Number

Year/Quarter              76-80           X(05)                YYYYQ

NOTE: Effective October 1, 2007, claims for ambulance services will continue to be submitted and priced using 5-digit ZIP Codes. Contractors will not need to make use of the ZIP9 file for ambulance claims.

Beginning in 2009, contractors shall maintain separate ZIP Code files for each year which will be updated on a quarterly basis. Claims shall be processed using the correct ZIP Code file based on the date of service submitted on the claim.

A ZIP Code located in a rural area will be identified with either a letter “R” or a letter “B.” Some ZIP Codes will be designated as rural due to the Rural Urban Commuting Area (RUCA) Score even though the ZIP Code may be located, in whole or in part, within an MSA or Core Based Statistical Area (CBSA).

A“B” designation indicates that the ZIP Code is in a rural county (or RUCA area) that is comprised by the lowest quartile by population of all such rural areas arrayed by population density. Effective for claims with dates of service between July 1, 2004 and December 31, 2010, contractors must apply a bonus amount to be determined by CMS to the base rate portion of the payment under the FS for ground ambulance services with a POP “B” ZIP Code. This amount is in addition to the rural bonus amount applied to ground mileage for ground transports originating in a rural POP ZIP Code.

Each calendar quarter beginning October 2007, CMS will upload updated ZIP5 and ZIP9 ZIP Code files to the Direct Connect (formerly the Network Data Mover). Contractors shall make use of the ZIP5 file for ambulance claims and the ZIP9 file as appropriate per IOM Pub. 100-04, Medicare Claims Processing Manual, chapter 1 –General Billing Requirements , section - Payment Jurisdiction Among Local Carriers for Services Paid Under the Physician Fee Schedule and Anesthesia Services and the additional information found in Transmittal 1193, Change Request 5208, issued March 9, 2007. The updated files will be available for downloading on approximately November 15th for the January 1 release, approximately February 15th for the April 1 release, approximately May 15th for the July 1 release, and approximately August 15th for the October 1 release.

1. Upon quarterly Change Requests communicating the availability of updated ZIP Code files, go to the Direct Connect and search for the files. Confirm that the release number (last 5 digits) corresponds to the upcoming calendar quarter. If the release number (last 5 digits) does not correspond to the upcoming calendar quarter, notify CMS.

2. After confirming that the ZIP Code files on the Direct Connect corresponds to the next calendar quarter, download the files and incorporate the files into your testing regime for the upcoming model release.

The names of the files will be in the following format: MU00.AAA2390.ZIP5.LOCALITY.Vyyyyr and MU00.AAA2390.ZIP9.LOCALITY.Vyyyyr where “yyyy” equals the calendar year and “r” equals the release number with January =1, April =2, July =3, and October =4. So, for example, the names of the file updates for October 2007 are MU00.AAA2390.ZIP5.LOCALITY.V20074 and MU00.AAA2390.ZIP9.LOCALITY.V20074. The release number for this file is 20074, release 4 for the year 2007.

When the updated files are loaded to the Direct Connect, they will overlay the previous ZIP Code files.

Payment Guideline for multiple ambulance usage

Jurisdiction of the claim is based on whether only one ambulance vehicle or multiple vehicles were used.

A. One Ambulance Vehicle Used

If only one vehicle is used to transport the patient from the point of initial pickup to the final destination, jurisdiction is with the carrier serving the point of origin, i.e., home station of the vehicle. This carrier has qualification information on the ambulance supplier and in most cases all other pertinent details necessary to adjudicate a claim.

EXAMPLE: A patient is picked up at the Johns Hopkins Hospital in Baltimore, Maryland and transported to his home in West Virginia by an ambulance dispatched from the area of the patient’s home. The carrier serving the point of origin of the ambulance, Nationwide Mutual Insurance Company, Part B carrier for the State of West Virginia, has jurisdiction of any claim filed. In this case Nationwide should have all the data necessary to make proper payment, i.e., certification of the ambulance company, price information and data pertaining to the nearest appropriate company, price information and data pertaining to the nearest appropriate facility. Had an ambulance whose home station was in Baltimore been used, the carrier servicing Baltimore, Maryland would have had jurisdiction. The Baltimore carrier would then have had
to obtain data concerning the nearest appropriate facility to the patient’s home from Nationwide

B. More Than One Vehicle Used

If more than one vehicle is used in transporting the patient to their destination, jurisdiction of the claim lies with:

• The carrier serving the home base of the ambulance taking the patient on the first leg of the trip, on a trip to a distant institution more remote than the nearest appropriate facility; or

• The carrier serving the home base of the ambulance taking the patient on the final leg of the trip home, on a trip from an institution more remote than the nearest appropriate facility.

• If there is no claim for the final leg of the trip, the carrier serving the patient’s home area handles any resulting claims or disallowance actions.

EXAMPLE: A patient is transported by ambulance from a hospital in Miami Beach, Florida to Miami International Airport and from there by air ambulance to LaGuardia Airport in Queens, New York City. At the airport he is picked up by an ambulance (based in Yonkers, New York) and taken to his home in Yonkers, New York. The carrier that handles the adjudication is the carrier whose area of responsibility includes Yonkers, New York, since partial reimbursement is based upon the nearest appropriate facility to his residence when he is being returned home from a distant institution.

In rules A and B above, the principle followed is that the carrier having the information to determine the “nearest appropriate facility” is the one to adjudicate the claim. In any event, before any partial reimbursement can be made, the carriers as designated in rules A and B, must have all the information concerning the patient’s transportation, from initial pickup to final destination.

Definition - What is Emergency, Medical necessity


Emergency - A serious medical condition or symptom resulting from Injury, Sickness or [1Mental Illness][2mental illness] which is both of the following:

• Arises suddenly

• In the judgment of a reasonable person, requires immediate care and treatment, generally received within 24 hours of onset, to avoid jeopardy to life or health

Medically Necessary (UHIC 2011 COC) - health care services provided for the purpose of preventing, evaluating, diagnosing or treating a Sickness, Injury, [Mental Illness,] [mental illness,] substance use disorder, condition, disease or its symptoms, that are all of the following as determined by us or our designee, within our sole discretion.

Non network Ambulance would be covered?

Benefit Level for Non-Emergency Ambulance:

The applicable benefit for eligible non-Emergency ambulance transportation depends on the patient pick-up location (origin) as follows:

1. If the patient is inpatient and is transported from a hospital to another hospital or inpatient facility, coverage levels for these ambulance services may vary. Please refer to the enrollee’s specific plan document to determine benefits. The following are UHIC examples for inpatient ambulance transfer:

a. UHIC 2001 COC: The Hospital Inpatient Stay section of the COC

b. UHIC 2007 and 2011 COC: the Ambulance Services section of the COC

2. If the patient is in a sub-acute setting and is transported to an outpatient facility and back (outpatient hospital, outpatient facility, or physician’s office), these ambulance services are covered under the benefits that apply to that sub-acute setting. For example, if the patient is at a Skilled Nursing Facility, the ambulance transport to an outpatient facility (dialysis facility, or radiation whether or not it is attached to a hospital) and back is covered under the Skilled Nursing Facility/Inpatient Rehabilitation Facility Services section of the COC.

Enrollee Pre-Service Notification Requirements for Non-Emergency Ambulance:

• If UHIC initiates the non-Emergency ambulance transportation, enrollee notification is not required.

• If UHIC does not initiate the non-Emergency ambulance transportation certain plans may require the enrollee or the provider to call in for notification. Please see the enrollee-specific plan documents for details on the notification requirements.

Additional Information:

• Provider notification requirements are not addressed by this document.

• Ambulance transportation that is done for convenience of the patient is not covered. Please see the Coverage Limitations and Exclusions section below for more information on non-covered ambulance transportation.

Benefit Level for Non-Network Ambulance (Emergency):

If the ambulance transportation is covered, non-network Emergency ambulance (ground, water, or air), is covered at the network level of deductible and coinsurance.

Additional Information:

• For UHIC Choice, Choice+, and Options PPO plans: Non-network Emergency ambulance is covered at a negotiated rate, or, at billed charges if a negotiated rate is not reached.

• For UHIC Non-Differential PPO plans: The benefits for network and non-network are the same level but these plans do not require billed charges to be paid on non-network ambulance.

• For UHIC Plans without a Network (eg, Managed Indemnity): These plans do not have network benefit levels. These plans do not require billed charges to be paid on ambulance services.

Some payment tips in Ambulance billing

Multi-Carrier System (MCS) Guidelines

Payment under the fee schedule for ambulance services:

• Includes a base rate payment plus a payment for mileage;

• Covers both the transport of the beneficiary to the nearest appropriate facility and all items and services associated with such transport; and

• Precludes a separate payment for items and services furnished under the ambulance benefit.

Payment for items and services is included in the fee schedule payment. Such items and services include but are not limited to oxygen, drugs, extra attendants, and EKG testing - but only when such items and services are both medically necessary and covered by Medicare under the ambulance benefit.

30.1.1 - MCS Coding Requirements for Suppliers

The ambulance fee schedule contains the following HCPCS coding logic:

• Seven categories of ground ambulance services;

• Two categories of air ambulance services;

• Payment based on the condition of the beneficiary, not on the type of vehicle used;

• Payment is determined by the point of pickup (as reported by the 5-digit ZIP Code);

• Increased payment for rural services; and

• Services and supplies included in base rate.
