Insurance Recode Variable

The Insurance Recode (2007+) variable is available in the 1973-2010 through the 1975-2016 SEER Research Data (November 2012 – November 2018 submissions). The variable has five categories derived from the NAACCR field, Primary Payer at Diagnosis. The recoded categories are:

1 – Uninsured Not insured Not insured, self pay 2 – Any Medicaid Indian/Public Health Service Medicaid Medicaid – Administered through a Managed Care plan Medicare with Medicaid eligibility 3 – Insured Private Insurance: Fee-for-Service Private Insurance: Managed care, HMO, or PPO, TRICARE Medicare – Administered through a Managed Care plan Medicare with private supplement Medicare with supplement, NOS and Military 4 – Insured, No Specifics Medicare/Medicare, NOS Insurance, NOS 5 – Insurance status unknown 6 – Blank(s)

Caution is urged when using this variable. Most patients who were 65 years of age and older at the time of diagnosis that were classified as “Uninsured”, having “Private Insurance”, or as “Insurance status unknown” were Medicare eligible, while patients diagnosed before 65 years of age were not. Stratification of this variable by these age groups may be warranted.
