CMS Claim Filing Instructions

Published 07/05/2018

The following instructions have been developed as a guide for submitting the CMS-1500 claim form to Palmetto GBA.

Dot Matrix Printers
Palmetto GBA will no longer accept paper claims printed on dot matrix printers. Paper claims are scanned and electronically entered into our processing system, and dot matrix printers produce type that is very light, which causes delays in processing your claims.

Even if you qualify to submit paper claims, consider submitting electronically. Electronic claims are processed more quickly, and you will generally receive reimbursement sooner than if you submit paper claims. Please contact our EDI Technology Support Center for more information.

Why Use the CMS-1500 Claim Form?
The CMS-1500 claim form answers the needs of many insurers. It is the basic form prescribed by the Centers of Medicare & Medicaid Services (CMS) for the Medicare program for claims from physicians and suppliers.

The revised version of the CMS 1500 claim form is version 2012-02-01 and is approved under the OMB control number 0938-1197. 

Reminder: The Administrative Simplification and Compliance Act (ASCA) prohibits Medicare from making payments on claims not submitted electronically on or after October 16, 2003, unless a provider is small (fewer than 10 full-time equivalent employees for providers required to bill Medicare carriers) or meets one of the very few limited exceptions to this requirement.

You must submit your claims electronically unless you meet the exceptions criteria established by ASCA.

If you qualify to submit paper claims, follow these instructions when completing your CMS-1500 claim forms:

Preparing the CMS-1500 Claim Form
Palmetto GBA scans claim information from the CMS-1500 claim form into the processing system. Successful scanning begins with the proper submission of claim data. It is important that claims be submitted with proper and legible coding. Claims that are not legible or properly coded will be returned or rejected.

CMS-1500 Helpful Hints
The font should be:

  • Legible (computerized or typed claims, laser printers are recommended)

Attachment Reminders:

  • All attachments must identify the patient’s name, Medicare ID number, date of service and other pertinent information
  • Attachments must be a full page (8 ½ x 11)
  • Operative reports, radiology reports, etc., should be submitted with paper claims only when either the coding guidelines indicate these reports are needed to process the service(s) or when a Medicare representative requests this additional information
  • Medicare Secondary Paper claims: Only attach the summary notice from the primary insurer that specifically corresponds to the claim you are submitting

Claims Submitted with Multiple Pages
Do not complete Item 28 for each CMS-1500 claim form. The total for Item 28 must be completed on the last CMS-1500 claim form. This only applies when there are more than six detail lines for one claim.

If multiple CMS-1500 claim forms are submitted with totals on each claim form, the claims will be scanned as separate claims and not as multi-page claim. 

Show the type of health insurance coverage applicable to this claim by checking the appropriate box (e.g., if a Medicare claim is being filed, check the Medicare box).
Insured's ID Number:
Enter the patient's Medicare ID number, whether Medicare is primary or secondary payer.
Patient's Name:
Enter the patient's last name, first name and middle initial, if any, as shown on the patient's Medicare card.
Patient's Birthdate:
Enter the patient's 8-digit birth date (MM/DD/YYYY) and sex.
Insured's Name:
If there is insurance primary to Medicare, either through the patient or spouse's employment or any other source, list the name of the insured here. When the insured and the patient are the same, enter the word "Same." If Medicare is primary, leave blank.
Patient's Address:
Enter the patient's mailing address and telephone number. On the first line enter the street address; the second line, the city and state; the third line, the ZIP Code and phone number.
Patient's Relationship to Insured:
Check the appropriate box to indicate the patient's relationship to the insured when Item 4 is completed
Insured's Address:
Enter the insured's address and telephone number. When the address is the same as the patient's, enter the word "Same." Complete this item only when Items 4, 6 and 11 are completed.
Patient Status:
Check the appropriate box for the patient's marital status and whether employed or a student.
Other Insured's Name:
Enter the last name, first name and middle initial of the enrollee in a Medigap policy, if it is different from that shown in Item 2. Otherwise, enter the word "Same." If no Medigap benefits are assigned, leave blank.

Note: Only participating physicians and suppliers are to complete Item 9 and its subdivisions, and only when the patient wishes to assign his or her benefits under a Medigap policy to the participating physician or supplier.

Participating physicians and suppliers must enter information required in Item 9 and its subdivision if requested by the patient. Participating physicians or suppliers sign an agreement with Medicare to accept assignment of Medicare benefits for all Medicare patients. A claim for which a patient elects to assign his or her benefits under a Medigap policy to a participating physician or supplier is called a mandated Medigap transfer. See Pub. 100-04, Chapter 28 (PDF, 619 KB) of the CMS Internet Only Manual.

Medigap: A Medigap policy meets the statutory definition of a "Medicare supplemental policy" contained in Section 1882 (g) (1) of Title XVIII of the Social Security Act and the definition contained in the NAIC Model Regulation, which is incorporated by reference to the statute. It is a health insurance policy or other health benefit plan offered by a private entity to those persons entitled to Medicare benefits and is specifically designed to supplement Medicare benefits. It fills in some of the gaps in Medicare coverage by providing payment for some of the charges for which Medicare does not have responsibility due to the applicability of deductibles, coinsurance amounts or other limitations imposed by Medicare. It does not include limited benefit coverage available to Medicare beneficiaries such as "specified disease" or "hospital indemnity" coverage. Also, it explicitly excludes a policy or plan offered by an employer to employees or former employees, as well as that offered by a labor organization to members or former members.

Do not list other supplemental coverage in Item 9 and its subdivisions at the time a Medicare claim is filed. Other supplemental claims are forwarded automatically to the private insurer if the private insurer contracts with the carrier to send Medicare claim information electronically. If there is no such contract, the beneficiary must file his/her own supplemental claim.
Other Insured's Policy or Group Number:
Enter the policy and/or group number of the Medigap enrollee preceded by Medigap, MG or MGAP.

Note: Item 9d must be completed if you enter a policy and/or group number in Item 9a.
Other Insured's Date of Birth:
Leave blank.

Employer's Name or School Name:
Leave blank if item 9d is completed. Otherwise, enter the claims processing address of the Medigap insurer. Use an abbreviated street address, two-letter postal code, and ZIP code copied from the Medigap insured's Medigap identification card. For example:

1257 Anywhere Street
Baltimore, MD 21204

is shown as "1257 Anywhere St. MD 21204."

Insurance Plan Name or Program Name:
Enter the Coordination of Benefits Agreement (COBA) Medigap-based Identifier (ID). Refer to IOM Pub. 100-04, chapter 28, section 70.6.4.
Is the Patient's Condition Related to:
Check "Yes" or "No" to indicate whether employment, auto liability or other accident involvement applies to one or more of the services described in Item 24. Enter the state postal code. Any items checked "Yes" indicate there may be other insurance primary to Medicare. Identify primary insurance information in Item 11.
Reserved for Local Use:
Use this item exclusively for Medicaid (MCD) information. If the patient is entitled to Medicaid, enter the patient's Medicaid number preceded by MCD.

Currently, Palmetto GBA receives an eligibility tape from Medicaid. This procedure will continue, and this will not be a required item at this time.
Insured's Policy Group or FECA Number:
This item must be completed. By completing this item, the physician or supplier acknowledges having made a good faith effort to determine whether Medicare is the primary or secondary payer.

Important: This item must not be left blank or the claim will be rejected.
  • If there is insurance primary to Medicare, enter the insured's policy or group number and proceed to Items 11a-11c. Items 4, 6 and 7 must also be completed
    Note: Enter the appropriate information in Item 11c if insurance primary to Medicare is indicated in Item 11
  • If there is no insurance primary to Medicare, enter the word "None," and proceed to Item 12
  • If the insured reports a terminating event with regard to insurance which had been primary to Medicare (e.g., insured, retired, etc.), enter the word 'None' and proceed to Item 11b
  • If a lab has collected previously and retained MSP information for a beneficiary, the lab may use that information for billing purposes of the non-face-to-face lab service. If the lab has no MSP information for the beneficiary, the lab will enter the word "None" in Item 11 of form CMS-1500, when submitting a claim for payment of a reference lab service. Where there has been no face-to-face encounter with the beneficiary, the claim will then follow the normal claims process. When a lab has a face-to-face encounter with a beneficiary, the lab is expected to collect the MSP information and bill accordingly.
  • Insurance primary to Medicare: Circumstances under which Medicare payment may be secondary to other insurance include:
    • Group health plan coverage
      • Working aged
      • Disability (large group health plan)
      • End stage renal disease
    • No fault and/or other liability
    • Work-related illness or injury
      • Workers' compensation
      • Black Lung
      • Veterans benefits
Note: For a paper claim to be considered for Medicare Secondary Payer benefits, a copy of the primary payer's explanation of benefits (EOB) notice must be forwarded along with the claim form. See Pub. 100-05, Chapter 3, Medicare Secondary Payer Manual (PDF, 477 KB).

Employer's Name or School Name:
Provide this information to the right of the vertical dotted line.
Insurance Plan Name or Program Name:
Enter the 9-digit Payer ID number for the primary insurer. If no Payer ID exists, then complete insurance primary payer's program or plan name (e.g., Blue Shield of [state]). If the primary payer's EOB does not contain the claims processing address, record the primary payer's claims processing address directly on the EOB. This is required if there is insurance primary to Medicare that is indicated in Item 11.
Is There Another Health Benefit Plan?
Leave blank. Not required by Medicare.
Patient's or Authorized Person's Signature:
The patient or authorized representative must sign and enter either a six-digit date (MM/DD/YY), eight-digit date (MM/DD/YYYY) or an alphanumeric date (e.g., January 1, 2009) unless the signature is on file. In lieu of signing the claim, the patient may sign a statement to be retained in the provider, physician or supplier file in accordance with Chapter 1, "General Billing Requirements." If the patient is physically or mentally unable to sign, a representative as specified in Pub. 100-04, Chapter 1, "General Billing Requirements," may sign on the patient's behalf. In this event, the statement's signature line must indicate the patient's name followed by the word "by," the representative's name, address, relationship to the patient and the reason the patient cannot sign. The authorization is effective indefinitely unless the patient or the patient's representative revokes this arrangement.

The patient's signature authorizes release of medical information necessary to process the claim. It also authorizes payment of benefits to the provider of service or supplier, when the provider of service or supplier accepts assignment of the claim.

Signature by mark (X): When an illiterate or physically handicapped enrollee signs by mark, a witness must enter his/her name and address next to the mark.
Insured's or Authorized Person's Signature:
The signature in this item authorizes payment of mandated Medigap benefits to the participating physician or supplier if required Medigap information is included in Item 9 and its subdivisions. The patient or his or her authorized representative signs this item or the signature must be on file as a separate Medigap authorization. The Medigap assignment on file in the participating provider or service or supplier's office must be insurer specific. It may state that the authorization applies to all services until it is revoked.

Name of Referring Physician or Other Source:
Enter the name of the referring or ordering physician if the service or item was ordered or referred by a physician.

All physicians who order services or refer Medicare beneficiaries must report this data. When a claim involves multiple referring and/or ordering physicians, a separate form CMS-1500 shall be used for each ordering/referring physician.
Enter one of the following qualifiers as appropriate to identify the role that the physician (or nonphysician practitioner) is performing:

Qualifier: DN — Provider role: Referring Provider

If this information is submitted voluntarily, it must be correct or it will cause rejection or denial of the claim. However, when the therapy service is provided incident to the services of a physician or nonphysician practitioner, then incident to policies continue to apply. For example, for identification of the ordering physician who provided the initial service, see Item 17 and 17b, and for the identification of the supervisor, see item 24J of this section.

Enter either a six-digit (MM/DD/YY) or an eight-digit (MM/DD/YYYY) x-ray date for chiropractor services (if an X-ray, rather than a physical examination was the method used to demonstrate the subluxation). By entering an X-ray date and the initiation date for course of chiropractic treatment in Item 14, the chiropractor is certifying that all the relevant information requirements (including level of subluxation) of Pub. 100-02, Medicare Benefit Policy Manual, Chapter 15, are on file, along with the appropriate x-ray and all are available for carrier review.

The six service lines in section 24 have been divided horizontally to accommodate submission of both the NPI and legacy identifier during the NPI transition and to accommodate the submission of supplemental information to support the billed service. The top portion in each of the six service lines is shaded and is the location for reporting supplemental information. It is not intended to allow the billing of 12 service lines. At this time, the shaded area in 24a through 24h is not used by Medicare. Future guidance will be provided on when and how to use this shaded area for the submission of Medicare claims.

When required to submit NDC drug and quantity information for Medicaid rebates, submit the NDC code in the red shaded portion of the detail line item in positions 01 through position 13. The NDC is to be preceded with the qualifier N4 and followed immediately by the 11 digit NDC code (e.g., N499999999999). Report the NDC quantity in positions 17 through 24 of the same red shaded portion. The quantity is to be preceded by the appropriate qualifier: UN (units), F2 (international units), GR (gram) or ML (milliliter). There are six bytes available for quantity. If the quantity is less than six bytes, left justify and space fill the remaining positions (e.g., UN2 or F2999999).

The form CMS-1500 has the ability to capture up to four modifiers. See Item 19 "CMS modifier 99" if you have more than four modifiers.

Enter the specific procedure code without a narrative description. However, when reporting an "unlisted procedure code" or a "not otherwise classified" (NOC) code, include a narrative description in item 19 if a coherent description can be given within the confines of that box. Otherwise, an attachment shall be submitted with the claim.

Diagnosis Code:
Enter the diagnosis code reference number or letter as shown in item 21 to relate the date of service and the procedures performed to the primary diagnosis. Enter only one reference number/letter per line item. When multiple services are performed, enter the primary reference number/letter for each service.
