workers' compensation policy. Such provider shall have one year after 
the date of the cancellation, denial or return of full or partial payment to

a secondary payor basis, regardless of such organization's timely filing 
requirements. 
(2) (A) Such  organization  shall  give  at  least  thirty  days'  advance 
notice to a provider by [mail, electronic mail or facsimile] certified mail, 
return receipt requested, electronic mail to such electronic mail address 
designated by such provider or facsimile, or through a secure electronic 
provider portal or electronic clearinghouse used for claims or remittance 
communications, of  the  organization's  cancellation,  denial  or  demand 
for the return of full or partial payment pursuant to subdivision (1) of 
this subsection. 
(B) If such organization demands the return of full or partial payment 
from  a  provider,  the  notice  required  under  subparagraph  (A)  of  this 
subdivision   shall   disclose   to   the   provider   (i)   the   amount   that   is 
demanded  to  be  returned,  (ii)  the  claim  that  is  the  subject  of  such 
demand, and (iii) the basis on which such return is being demanded.

under subparagraph (A) of this subdivision, a provider may appeal such 
cancellation,  denial  or  demand  in  accordance  with  the  procedures 
provided  by  such  organization,  which  shall  include,  but  need  not  be 
limited to, an electronic appeal process. If any such organization fails to 
notify the provider of such organization's determination of such appeal 
not later than thirty business days after receipt of such appeal from such 
provider, such appeal shall be construed in favor of such provider. Any

demand for the return of full or partial payment shall be stayed during 
the pendency of such appeal. 
(D) If  there  is  no  appeal  or  an  appeal  is  denied,  such  provider  may 
resubmit an adjusted claim, if applicable, to such organization, not later 
than   thirty   days   after   the   receipt   of   the   notice   required   under 
subparagraph  (A)  of  this  subdivision  or  the  denial  of the  appeal, 
whichever   is   applicable,   except   that   if   a   return  of   payment  was 
demanded  pursuant  to  subparagraph  (C)  of  subdivision  (1)  of  this 
subsection, such claim shall not be resubmitted. 
(E) A provider shall have one year after the date of the written notice 
set forth in subparagraph (A) of this subdivision to identify any other 
appropriate insurance coverage applicable on the date of service and to 
file a claim with such insurer, health care center or other issuing entity, 
regardless of such insurer's, health care center's or other issuing entity's 
timely filing requirements. 
Sec.  2.  (NEW)  (Effective  January  1,  2027)  (a)  For  the  purposes  of  this 
section,  "health  care  provider"  has  the  same  meaning  as  provided  in 
section 38a-477aa of the general statutes. 
(b)  (1)  No  insurer,  health  care  center,  fraternal  benefit  society, 
hospital service corporation, medical service corporation or other entity 
delivering, issuing for  delivery, renewing, amending or continuing an 
individual  or  group  health  insurance  policy  in  this  state  on  or  after 
January 1, 2027, providing coverage of the type specified in subdivisions
