|(a) Applicability of this rule is as follows: (1) This section applies to professional medical services provided in the Texas workers' compensation system, other than: (A) workers' compensation specific codes, services, and programs described in §134.204 of this title (relating to Medical Fee Guideline for Workers' Compensation Specific Services); (B) prescription drugs or medicine; (C) dental services; (D) the facility services of a hospital or other health care facility; and (E) medical services provided through a workers' compensation health care network certified pursuant to Insurance Code Chapter 1305, except as provided in Insurance Code Chapter 1305. (2) This section applies to professional medical services provided on or after March 1, 2008. (3) For professional services provided between August 1, 2003 and March 1, 2008, §134.202 of this title (relating to Medical Fee Guideline) applies. (4) For professional services provided prior to August 1, 2003, §134.201 of this title (relating to Medical Fee Guideline for Medical Treatments and Services Provided under the Texas Workers' Compensation Act) and §134.302 of this title (relating to Dental Fee Guideline) apply. (5) "Medicare payment policies" when used in this section, shall mean reimbursement methodologies, models, and values or weights including its coding, billing, and reporting payment policies as set forth in the Centers for Medicare and Medicaid Services (CMS) payment policies specific to Medicare. (6) Notwithstanding Medicare payment policies, chiropractors may be reimbursed for services provided within the scope of their practice act. (7) Specific provisions contained in the Texas Labor Code or the Texas Department of Insurance, Division of Workers' Compensation (Division) rules, including this chapter, shall take precedence over any conflicting provision adopted or utilized by CMS in administering the Medicare program. Independent Review Organization (IRO) decisions regarding medical necessity made in accordance with Labor Code §413.031 and §133.308 of this title (relating to MDR by Independent Review Organizations), which are made on a case-by-case basis, take precedence in that case only, over any Division rules and Medicare payment policies. (8) Whenever a component of the Medicare program is revised, use of the revised component shall be required for compliance with Division rules, decisions, and orders for professional services rendered on or after the effective date, or after the effective date or the adoption date of the revised component, whichever is later. (b) For coding, billing, reporting, and reimbursement of professional medical services, Texas workers' compensation system participants shall apply the following: (1) Medicare payment policies, including its coding; billing; correct coding initiatives (CCI) edits; modifiers; bonus payments for health professional shortage areas (HPSAs) and physician scarcity areas (PSAs); and other payment policies in effect on the date a service is provided with any additions or exceptions in the rules. (2) A 10 percent incentive payment shall be added to the maximum allowable reimbursement (MAR) for services outlined in subsections (c) - (f) and (h) of this section that are performed in designated workers' compensation underserved areas in accordance with §134.2 of this title (relating to Incentive Payments for Workers' Compensation Underserved Areas). (c) To determine the MAR for professional services, system participants shall apply the Medicare payment policies with minimal modifications. (1) For service categories of Evaluation & Management, General Medicine, Physical Medicine and Rehabilitation, Radiology, Pathology, Anesthesia, and Surgery when performed in an office setting, the established conversion factor to be applied is $52.83. For Surgery when performed in a facility setting, the established conversion factor to be applied is $66.32. (2) The conversion factors listed in paragraph (1) of this subsection shall be the conversion factors for calendar year 2008. Subsequent year's conversion factors shall be determined by applying the annual percentage adjustment of the Medicare Economic Index (MEI) to the previous year's conversion factors, and shall be effective January 1st of the new calendar year. The following hypothetical example illustrates this annual adjustment activity if the Division had been using this MEI annual percentage adjustment: The 2006 Division conversion factor of $50.83 (with the exception of surgery) would have been multiplied by the 2007 MEI annual percentage increase of 2.1 percent, resulting in the $51.90 (with the exception of surgery) Division conversion factor in 2007. (d) The MAR for Healthcare Common Procedure Coding System (HCPCS) Level II codes A, E, J, K, and L shall be determined as follows: (1) 125 percent of the fee listed for the code in the Medicare Durable Medical Equipment, Prosthetics, Orthotics and Supplies (DMEPOS) fee schedule; (2) if the code has no published Medicare rate, 125 percent of the published Texas Medicaid fee schedule, durable medical equipment (DME)/medical supplies, for HCPCS; or (3) if neither paragraph (1) nor (2) of this subsection apply, then as calculated according to subsection (f) of this section. (e) The MAR for pathology and laboratory services not addressed in subsection (c)(1) of this section or in other Division rules shall be determined as follows: (1) 125 percent of the fee listed for the code in the Medicare Clinical Fee Schedule for the technical component of the service; and, (2) 45 percent of the Division established MAR for the code derived in paragraph (1) of this subsection for the professional component of the service. (f) For products and services for which no relative value unit or payment has been assigned by Medicare, Texas Medicaid as set forth in §134.203(d) or §134.204(f) of this title, or the Division, reimbursement shall be provided in accordance with §134.1 of this title (relating to Medical Reimbursement). (g) When there is a negotiated or contracted amount that complies with Labor Code §413.011, reimbursement shall be the negotiated or contracted amount that applies to the billed services. (h) When there is no negotiated or contracted amount that complies with Labor Code §413.011, reimbursement shall be the least of the: (1) MAR amount; (2) health care provider's usual and customary charge, unless directed by Division rule to bill a specific amount; or (3) fair and reasonable amount consistent with the standards of §134.1 of this title. (i) Health care providers (HCPs) shall bill their usual and customary charges using the most current Level I (CPT codes) and Level II HCPCS codes. HCPs shall submit medical bills in accordance with the Labor Code and Division rules. (j) Modifying circumstance shall be identified by use of the appropriate modifier following the appropriate Level I (CPT codes) and Level II HCPCS codes. Division-specific modifiers are identified and shall be applied in accordance with §134.204(n) of this title (relating to Medical Fee Guideline for Workers' Compensation Specific Services). When two or more modifiers are applicable to a single CPT code, indicate each modifier on the bill.
