When salary protection insurance benefits are payable to an individual or an individual's beneficiary, the amount of salary protection insurance plus the amount of any in-force disability income insurance, if the individual can obtain disability insurance from an admitted insurer, shall not exceed seventy-five percent (75%) of the individual's annual earned income. As used in this section, "disability income insurance" has the same meaning as "accident and health insurance" in G.S. 58-7-15(3).
N.C. Gen. Stat. § 58-21-22
