Health Law Advocates (HLA) is a public interest law firm whose mission is to provide pro bono legal representation to low-income residents experiencing difficulty accessing or paying for needed medical services. HLA is committed to ensuring universal access to quality health care in Massachusetts, particularly for those who are most at risk due to such factors as race, gender, disability, age, or geographic location. With its partner organization, Health Care For All, HLA combines legal expertise with grassroots organizing and policy reform to advance the statewide movement for universal health care access. They also assist people having difficulty getting adequate medical care while incarcerated. HLA specializes in challenging denials of health insurance enrollment (commercial and public insurance), fighting denials of coverage for specific health care services (commercial and public insurance), protecting patients from illegal medical billing and collection practices and obtaining access to health care through state agencies and school systems, especially for children.
