Texas Workers' Compensation Certified Doctor Addresses and Certification Periods

A registry of Texas healthcare providers certified for Maximum Medical Improvement (MMI) and Designated Doctor evaluations. The dataset includes doctor names, certification periods, phone numbers, and multiple address types. It is maintained by the Texas Department of Insurance, Division of Workers' Compensation and was last updated in March 2026.

Use Cases

• Map provider locations using `City Name`, `State Code`, and `Postal Code` for geographic coverage analysis.
• Analyze certification validity periods by comparing `MMI Start Date` and `MMI End Date` for compliance checks.
• Identify primary contact points for providers by filtering on `Primary Address Flag` and using `Primary Phone`.
• Distinguish between practice and mailing addresses using the `Practice Address` and `Mailing Address` columns for administrative correspondence.
• Model doctor availability by categorizing addresses as `DD Traveling Address` or `DD Non-Traveling Address`.

Strengths

• Contains 30 distinct columns covering certification, contact, and location details.
• Includes temporal data fields (`MMI Start Date`, `DDL End Date`) for tracking certification status.
• Maintained by the authoritative state agency, the Texas Department of Insurance.

Limitations

• Sample size and total row count are unknown, limiting assessment of statistical power.
• Geographic coverage is explicitly limited to the state of Texas, reducing broader applicability.
• Data completeness for fields like `Middle Name` or `Suffix` cannot be verified without sample data.
