A carrier and its subcontractors shall adopt the aforementioned coding standards and guidelines, and all changes thereto, in their entirety, which shall be effective on the same date as the national implementation date established by the entity implementing the coding standards.

(b) Subject to subsection (c), a carrier and its subcontractors shall, without local customization, use the standardized claim formats for processing health care claims as adopted by the National Uniform Claim Committee and the National Uniform Billing Committee and implemented pursuant to the Health Insurance Portability and Accountability Act. A carrier and its subcontractors shall, without local customization, adopt and routinely process all changes to such formats which shall be effective on the same date as the implementation date established by the entity implementing the formats.

(c) Except for the requirements for consistency and uniformity in coding patient diagnostic information and patient care service and procedure information, this section shall not modify or supersede a carrier's or its subcontractor's payment policy, utilization review policy or benefits under a health benefit plan. Nothing in this section shall further preclude a carrier or a subcontractor thereof from adjudicating a claim pursuant to its billing guidelines, payment policies, provider contracts or health benefit plans.

(d) Carriers and their subcontractors shall accept and recognize all claims submitted by health care providers pursuant to this section.
