Cal. Ins. Code § 10192.19

(a) An issuer shall provide a copy of any Medicare supplement advertisement intended for use in this state whether through written, radio, or television medium to the commissioner for review at least 30 days before dissemination of the advertisement. The advertisement shall comply with all applicable laws of California.
(b) A television, radio, mail, or newspaper advertisement which is designed to produce leads either by use of a coupon or a request to write or otherwise contact the issuer, a production agent, or other person or a subsequent advertisement prior to contact shall include information disclosing that an agent may contact the applicant if that is the fact. In addition, an agent who makes contact with a consumer, as a result of acquiring that consumer’s name from a lead generating device shall disclose that fact in the initial contact with the consumer.
(c) No issuer, agent, broker, solicitor, or other person or other entity shall solicit residents of this state for the purchase of a Medicare supplement policy through the use of a true or fictitious name which is deceptive or misleading with regard to the status, character, or proprietary or representative capacity of the entity or person or the true purpose of the advertisement.
(d) For purposes of this section, an advertisement includes envelopes, stationery, business cards, or other materials designed to describe and encourage the purchase of a Medicare supplement policy.
(e) Advertisements may not employ words, letters, initials, symbols, or other devices which are so similar to those used by governmental agencies, a nonprofit or charitable institution, senior organization, or other insurer that they could have the capacity or tendency to mislead the public. Examples of misleading materials, include, but are not limited to, those which imply any of the following:
1. (1) The advertised coverages are somehow provided by or are endorsed by the governmental agencies or the other insurer.
2. (2) The advertiser is the same as, is connected with, or is endorsed by, the governmental agencies, other entity, or other insurers.
3. (3) That the advertised coverages are somehow provided by or are endorsed by the governmental agencies, other entity, or other insurers.
(f) No advertisement shall use the name of a state or political subdivision thereof in a policy name or description.
(g) No advertisement may use any name, service mark, slogan, symbol, or a device in any manner that implies that the issuer or the Medicare supplement policy advertised, or that any agency who may call upon the consumer in response to the advertisement is connected with a governmental agency, such as the Social Security Administration.
(h) No advertisement shall be used that fails to prominently display the disclaimer to the effect of “Not Connected with or endorsed by the U.S. Government or the federal Medicare program.”
(i) No advertisement may imply that the reader may lose a right or privilege or benefit under federal, state, or local law if he or she fails to respond to the advertisement.
(j) An issuer, agent, broker, or other entity may not use an address so as to mislead or deceive as to the true identity, location, or licensing status of the issuer, agent, broker, or other entity.
(k) No issuer may use, in the trade name of its insurance policy, any terminology or words so similar to the name of a governmental agency or governmental program as to have the tendency to confuse, deceive, or mislead a prospective purchaser.
(l) All advertisements used by agents, producers, brokers, solicitors, or other persons of an issuer must have prior written approval of the issuer before they may be used.
(m) No issuer, agent, broker, or other entity may solicit a particular class by use of advertisements which state or imply that the occupational or other status as members of the class entitles them to reduced rates on a group or other basis when, in fact, the policy being advertised is sold only on an individual basis at regular rates.
