No DPC law at present, but House Bill 159 "An Act exempting certain health care agreements from regulation as insurance" was proposed in 2016 (my thoughts about this legislation are included below).  There are multiple DPC practices within Alaska's borders. When designing your contract be sure to review Alaska Insurance Code, most importantly AS 21.12.050 (Insurance language) and AS 21.86.900 (Health Maintenance Organization language).  The Alaska State Medical Board has issued brief guidelines on physician dispensing.

Sec. 21.12.050. Health and health care insurance defined.
   (a) Health insurance is insurance of human beings (1) against bodily injury, disablement, or death by accident or accidental means; (2) against the resulting expenses of the injury, disablement, or death; (3) against disablement or expense resulting from sickness or childbirth; (4) against expense incurred in prevention of sickness; (5) for dental care; and (6) including every insurance that applies to injury, disablement, or death. Transaction of health insurance includes disability insurance and stop-loss insurance but does not include workers' compensation insurance. Health care insurance described in (b) of this section is a type of health insurance under this subsection.
   (b) Health care insurance means that part of health insurance that provides, delivers, arranges for, pays for, or reimburses any of the costs of medical care.
   (c) In this section, "stop-loss insurance" means insurance purchased by a self-insured employer to cover benefits the employer incurs in excess of a preset limit.

Sec. 21.86.900 Definitions
(10) "health maintenance organization" means a person that undertakes to provide or arrange for basic health care services to enrollees on a prepaid basis;

(3) "basic health care services" means emergency care, inpatient hospital and physician care, and outpatient medical services, but does not include mental health services or services for alcohol or drug abuse;

Here are some thoughts about the proposed legislation (HB 159):

HB 159 does not actually use and appropriately define the term "Direct Primary Care."  (Note the easy to understand three part definition.)  For some odd reason there is fear that using this term would exclude outpatient based specialists from practicing in this manner - this is not the case.  We should ditch the phrase "routine" in section K(1) and replace it a "direct primary care or similar medical services arrangement." 
In section K(5) we should strike the phrase "specific routine."  Similarly at the end of the legislation we should strike the entire section (L)(3) that seeks to define "routine health care services."  Simply require that the DPC contract specify the health care services that it covers.  Attempting to give it an adjective such as "routine" will inevitably back you into a corner where you make some physicians narrow their scope unnecessarily and obligate others to expand it uncomfortably.  Remember that we should anticipate some level of scope restrictions to come on the federal side (when the IRS has to interpret legislation designed to make DPC HSA deductible, then by necessity they will need to decide which DPC services "count").
In section K(9) - this was written as an attempt to prohibit fee for noncovered service practices (aka concierge) from double dipping and claiming to be DPC.  A wise concept, but the problem is that the language was poorly drafted.  As written this section causes collateral damage.  If read literally, it could prohibit a DPC practice from billing an "other person" (such as an individual's employer) for the services provided under the agreement.  If we appropriately defined DPC using the three part definition listed above then sections like this are unnecessary.
