Items 11a - 13 - Patient and Insured Information
10.3 - Items 11a - 13 - Patient and Insured Information
(Rev. 3083, Issued: 10-02-14, Effective: CMS-1500: 01-06-14, ICD-10 – Upon
Implementation of ICD-10, Implementation: CMS-1500: 01-06-14, ICD-10 - Upon
Implementation of ICD-10)
Item 11a - Enter the insured's 8-digit birth date (MM | DD | CCYY) and sex if different
from item 3.
Item 11b - Form version 08/05: Enter employer's name, if applicable. If there is a
change in the insured's insurance status, e.g., retired, enter either a 6-digit (MM | DD |
YY) or 8-digit (MM | DD | CCYY) retirement date preceded by the word, "RETIRED."
Form version 02/12: provide this information to the right of the vertical dotted line.
Item 11c - Enter the 9-digit PAYERID number of the primary insurer. If no PAYERID
number exists, then enter the complete primary payer's program or plan name. 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.
Item 11d - Leave blank. Not required by Medicare.
Item 12 - The patient or authorized representative must sign and enter either a 6-digit
date (MM | DD | YY), 8-digit date (MM | DD | CCYY), or an alpha-numeric date (e.g.,
January 1, 1998) 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 specified in chapter 1, may sign on the
patient's behalf. In this event, the statement's signature line must indicate the patient's
name followed by “by” the representative's name, 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.
NOTE: This can be "Signature on File" and/or a computer generated signature.
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 on 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.
Item 13 - The patient’s signature or the statement “signature on file” in this item
authorizes payment of medical benefits to the physician or supplier. The patient or
his/her authorized representative signs this item or the signature must be on file
separately with the provider as an authorization. However, note that when payment
under the Act can only be made on an assignment-related basis or when payment is for
services furnished by a participating physician or supplier, a patient’s signature or a
“signature on file” is not required in order for Medicare payment to be made directly to
the physician or supplier.
The presence of or lack of a signature or “signature on file” in this field will be indicated
as such to any downstream coordination of benefits trading partners (supplemental
insurers) with whom CMS has a payer-to-payer coordination of benefits relationship.
Medicare has no control over how supplemental claims are processed, so it is important
that providers accurately address this field as it may affect supplemental payments to
providers and/or their patients.
In addition, 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/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 of service/supplier's office must be
insurer specific. It may state that the authorization applies to all occasions of service
until it is revoked.
NOTE: This can be "Signature on File" signature and/or a computer generated signature.
