Health insurer Humana Inc. chopped its spending on second-quarter federal lobbying by 33 percent compared to 2010, as it focused only on a health care overhaul-related bill and a handful of other Congressional acts.

The Louisville, Ky., company spent $180,000 in the April-to-June period. That also represented a 35 percent drop from spending in this year's first quarter.

Humana lobbied to repeal an annual fee on health insurance providers enacted by the overhaul, which was passed last year and aims to eventually cover millions of uninsured people. The act promises new business for insurers, but it also imposes a host of fees and restrictions on the industry.

The insurer also lobbied on the FIT Kids Act, the Small Business Health Relief Act of 2011 and the Medicare Data Access for Transparency and Accountability Act, according to lobbying reports filed with the clerk of the House of Representatives.

Humana is the fifth-largest publicly traded health insurer based on enrollment. It sells commercial health insurance and Medicare Advantage plans, which are privately run versions of the government's Medicare program for the elderly and disabled. It also administers Medicaid coverage and provides coverage through the military's Tricare program.

Besides Congress and the White House, Humana also lobbied the Centers for Medicare and Medicaid Services.
