How long can creditors come after you for medical debt?

If the debt is contractually valid, and you are not disputing the debt, it will be based on the initial contract, and the Statuate of Limitations (SOL). Each state may vary on the SOL. In addition, some Medical Providers (original creditor:e.g., hospital, physician, etc) and individual States, have specific guidelines on the collection of medical debt. Reporting on credit history may be for 7 years, again based on the Medical Provider, and the state's guidelines.
