Workers’ Comp Premium Credits by State: Oil & Gas Guide

Safety-based mechanism overview:

Every major oil & gas state offers a loss-sensitive or safety-based way to lower workers’ comp premium, but the mechanism varies. Some states layer statutory certification credits, medical-network discounts, or drug-free-workplace credits on top of the standard experience-modification (X-Mod) system. Others offer nothing beyond the mod itself.

• Texas: 12% certified health-care-network discount plus safety-group discounts (~12%) and dividends
• Oklahoma: Tiered 10–15% WCPR credit plus Certified Workplace Medical Plan discounts
• Wyoming: Stackable safety, consultation, and drug-free discounts (tiers of 3–10% each)
• New Mexico: Mandates a safety inspection for larger employers but offers no premium credit
• California: No state safety-certification credit; savings come from the X-Mod and carrier schedule rating (±25%)
• Colorado: Cost Containment Certification (up to 5% typical, 10% statutory ceiling) plus a 2.5% Designated Medical Provider credit
• Louisiana: Statutory 5% safety-program credit plus 2% cost-containment-meeting credit
• North Dakota: 10% Safety Management Program plus up to 15% Safety Action Menu (25% combined cap)

The Two-Track System

U.S. workers’ comp rating runs on two tracks: universal loss-sensitive rating that exists everywhere, and state-specific statutory credits that don’t.

Track one: experience and schedule rating

In 36 of 51 U.S. jurisdictions, including Colorado, Louisiana, New Mexico, Oklahoma, and Texas, the National Council on Compensation Insurance (NCCI) administers classifications and rating. The experience modification factor (the “mod,” “e-mod,” or “X-Mod”) is a multiplier on manual premium based on about three years of loss history, excluding the most recent year. A mod below 1.00 reduces premium. On top of the mod, carriers apply schedule rating—subjective credits or debits for risk characteristics not captured in experience—up to 50% in NCCI’s plan, though many states cap it tighter, commonly ±25%. NCCI rolled out state-specific split points for the mod formula on filings on or after Nov. 1, 2023.

Eleven states run independent rating bureaus with parallel systems: California’s WCIRB, New York’s NYCIRB, Pennsylvania’s PCRB, New Jersey’s NJCRIB, North Carolina’s NCRB, Wisconsin’s WCRB, and others. California, New York, Pennsylvania, Delaware, and New Jersey use distinct experience rating plans unaffected by NCCI’s mod changes. Four monopolistic state funds (North Dakota’s WSI, Wyoming’s DWS, Ohio BWC, and Washington L&I) prohibit private WC insurers entirely and set their own base rates and discount menus.

Track two: statute-based credits

Layered on top (or, in monopolistic states, instead), many states run certification, medical-network, or drug-free-workplace programs with fixed percentage credits. These often carry notice or acknowledgment requirements that brokers must affirmatively manage — and they’re easy to leave on the table because no one is obligated to advertise most of them.

Texas is a special case within track one: competitive but not an NCCI-mandated-rate state. TDI adopts NCCI advisory loss costs, but insurers may rate off their own relativities, TDI relativities, or NCCI loss costs, using an NCCI-style experience rating plan.

State-by-State Detail

Texas (HCN and Group Dividends)

• Certified Health Care Network (HCN) discount. Created by the 2005 H.B. 7 reforms and certified by TDI under Insurance Code Chapter 1305. Texas Mutual’s WorkWell, TX network gives a 12% premium discount and covers 231 of Texas’s 254 counties. Acuity/CorVel’s Texas CorCare network offers most eligible policyholders 10%. Under §1305.005 and 28 TAC §10.60, the carrier must deliver a Notice of Network Requirements. The employer must deliver it to employees (new hires by day three or upon injury), obtain signed acknowledgments, post the notice, and keep records. An injured employee is not required to use the network if notice or acknowledgment wasn’t delivered. This is the clearest parallel to Colorado’s notice/acknowledgment mandate. However, Texas’s notice runs to employees while Colorado’s runs to the insured.
• Safety group discounts and dividends. State law allows employers in similar industries to buy as a group. Texas Mutual safety groups pay up-front discounts of about 12.2–12.4% plus potential performance dividends. The TXOGA (Texas Oil & Gas Association) safety group with Texas Mutual has paid multimillion-dollar dividends and is directly relevant to oil & gas clients.

Oklahoma (NCCI)

• WCPR (Workers’ Compensation Premium Reduction). Administered by the Oklahoma Department of Labor since 1988 (Title 40 O.S. § 414; Title 36 O.S. § 924.2; schedule at Okla. Admin. Code § 380:41-3-5). Tiered inversely by premium size: 15% for $1–$5,000 down to 10% for $101,001 and up. It requires a full-service ODOL safety consultation requested 60 days before renewal, hazard correction, an effective safety program, documented loss reductions, and at least one year of participation. Once ODOL issues the certificate, mailed directly to the insurer, the credit is mandatory. §924.2 says insurers “shall allow” it, and willful failure to apply it draws a fine of at least $10,000 or three times the reduction, whichever is greater. Certificates run one year. Insurers report reductions on OID Form 3000.
• Certified Workplace Medical Plan (CWMP). Managed-care option (Title 85A §64, created 1994) administered through the State Department of Health; premium discounts may be available to enrolled employers—Oklahoma’s medical-network analog.
• Safety Pays OSHA Consultation. Free ODOL consultation carrying a $1,000 taxable-income exemption (Title 68 O.S. § 2358), separate from WCPR.

Wyoming (Monopolistic; DWS)

Discounts apply to the base rate, not the mod (Wyo. Stat. § 27-14-201(o); WC Rules Ch. 2 §§ 8–10). They stack, offering the state 20%+ potential savings:

• Safety Discount Program: three tiers up to 10% (top tier requires a safety committee/coordinator, documented meetings, loss ratio ≤10%, and no fatality, catastrophe, willful, or repeat serious offense).
• Health & Safety Consultation Discount: four tiers — 3%, 5%, 7%, 10% — tied to onsite surveys (by Wyoming OSHA Consultation, WC Safety and Risk, the State Mine Inspector, or an approved third party) and, at the top tier, SHARP/VPP participation. Effective up to three years.
• Drug & Alcohol (Drug-Free Workplace) discount: 5–10% for an approved program with pre-employment, random, post-accident, and reasonable-suspicion testing plus training and annual application.
• A Deductible Program and free Risk Management analysis are also available; experience rating applies within the state system.

New Mexico (NCCI; mandate without a credit)

• NMSA 1978, § 52-1-6.2 requires an annual safety inspection for employers with a WC premium of $15,000 or more (or certified self-insureds). A safety affidavit is due to the WCA within 60 days of issuance or renewal. There is no premium discount attached; it is a compliance mandate, not a credit. Loss-sensitive savings come from NCCI experience rating and carrier schedule rating. Carriers such as New Mexico Mutual offer safety consulting but no statutory certification credit.

California (WCIRB; independent)

• No state safety-certification credit. The WCIRB administers the mandatory Experience Rating Plan (10 CCR §2353.1). More than 130,000 California businesses are experience rated, representing roughly 80% of WC premiums paid. Carriers may apply schedule rating up to ±25% under open/competitive rating with WCIRB advisory pure premium rates. Employers control medical treatment via Medical Provider Networks (MPNs), a claims-cost tool, not a premium credit.

Colorado

• The Premium Cost Containment (PCC) Program, administered by the Cost Containment Board within the Division of Workers’ Compensation (CDLE), certifies employers with a documented risk-management or safety program in place for at least a year. Carrier pages describe a direct discount of up to 5%. The CDLE program page cites up to 10% under the statute (§ 8-14.5-101 et seq., C.R.S.; rules at 7 CCR 1101-6). Five percent is the typical realized credit; 10% is the statutory ceiling. Certification runs one year initially, renews for one year, then moves to three-year cycles.
• To qualify for PCC certification, the employer must implement and document a qualifying safety and loss-control program for at least one year. This includes a written safety policy, a safety coordinator and/or safety committee, posted safety rules, employee safety training, a designated medical provider program, written claims management and return-to-work procedures, and supporting loss history and payroll information submitted with the application.
• Colorado separately offers a 2.5% Designated Medical Provider (DMP) credit for employers who establish and maintain a compliant designated-provider program: selecting and providing a list of designated medical providers for work-related injuries, meeting Colorado’s requirements on the number and availability of providers, delivering required notices to employees and injured workers, and maintaining documentation of the program’s implementation.
• The Notice/Acknowledgment Letter is Colorado’s mechanism for making sure these credits aren’t silently left on the table: the state requires that the insured be notified these credits may be available and allowed to pursue them if eligible. The insured’s signature acknowledges only that they’ve been informed — it does not mean the policy is receiving either credit. This employer-facing disclosure requirement is unusually explicit among these states. Carriers also apply schedule rating within a ±25% band.
• Colorado watch item: HB 25-1300, signed June 2025 and effective Jan. 1, 2028, expands injured-worker physician choice and requires employers to notify workers of that right within seven days, potentially reshaping the DMP credit mechanics.

Louisiana (NCCI)

• The closest statutory twin to Colorado, administered by the Louisiana Workforce Commission Office of Workers’ Compensation.
• Cost-Containment Meeting credit (La. R.S. 23:1178): 2% for sending a designated representative to an OSHA-section cost-containment meeting.
• Occupational Safety & Health Program credit (La. R.S. 23:1179): an additional 5% — explicitly stackable with §1178 — for implementing the OSHA section’s program to its satisfaction, including a workplace hazard survey and correction of all hazards. All WC insurers “shall allow” the reduction. Certification lasts one year; requalification is allowed only once every four years.
• Drug-free workplace credits for certified programs, plus a state income tax credit (5% of qualified substance-abuse treatment expenses).

North Dakota (monopolistic — WSI)

• Safety Management Program (SMP): 10% discount, applied after experience-rating adjustments. Requires a written safety policy signed by top management, proactive goals, a safety committee or coordinator, and an annual WSI audit. Apply at least 30 days before the policy period.
• Safety Action Menu (SAM): up to 15% more (multiple 5% items), combinable with SMP to a 25% cap in the same premium period.
• Designated Medical Provider (DMP): employers select and post providers; WSI may not pay for treatment by a non-designated provider absent referral (emergency care exempt). Mirrors Colorado’s DMP concept but functions as a claims-control tool rather than a fixed-percentage credit.
• Other: experience rating begins in year five (75% discount to 75% surcharge; requires ≥$25,000 aggregate premium over five years), a no-claims performance discount (10% credit if no claim over $250), and a Large Deductible Program.

Program Review Topics

1. Understand the distinction between universal mod/schedule-rating levers and the statute-based credits that vary by state and often require affirmative notice.
2. If you work in one of these states, know your biggest work comp credit advantage:
   • Texas: certified HCN (12% with Texas Mutual) plus the TXOGA safety group (~12% up-front plus dividends). Confirm the network notice/acknowledgment paperwork is delivered and signed — failure voids the network requirement and risks the discount.
   • North Dakota: SMP + SAM to the 25% cap; file the DMP designation; apply ≥30 days before the policy period.
   • Oklahoma: WCPR certification (10–15% by premium size) — mandatory once certified — plus a CWMP for medical-cost control.
   • Wyoming: stack all three discount programs against the base rate.
   • Louisiana: capture the 2% + 5% statutory credits plus drug-free credits.
3. Reset your expectations in New Mexico and California. Savings come from mod management, schedule-rating negotiation, and claims/medical-network control. In New Mexico, treat the $15,000+ inspection as a compliance obligation to document.
4. Benchmark based on your X-Mod. If your X-Mod is already well below 1.00, the marginal value of a schedule credit shrinks, and certification credits (which hit base/manual premium) become the higher-leverage move. If a monopolistic-fund client (ND/WY) has a poor loss ratio, the tiered safety programs still apply to the base rate and are worth pursuing even when experience surcharges bite.
5. If in Colorado, watch HB 25-1300 for DMP changes effective 2028.

Program Review Caveats

• Carrier-specific percentages (Texas Mutual 12%, Acuity/CorVel 10%) are set by the insurer/network, not statute, and can change.
• Colorado’s credit: 5% is typical, up to 10% is statutory.
• Texas dividends are declared annually on historical loss performance, never promised.
• Oklahoma’s “up to 15%” applies only at the smallest premium band; WCPR with NCCI schedule credits or group self-insurance discounts are not the same thing. No affirmative insurer duty to advertise WCPR/CWMP was located in statute. Confirmed obligations are only certificate delivery to the insurer and annual-statement reporting.
• Program names, tiers, and thresholds change with legislative sessions and annual rate filings (Wyoming’s base rates change yearly).
