Billing Specialists

At Rabkin Dermatopathology Laboratory, P.C., all insurance and patient billing is completed in-house.

Our Billing Specialists are available to answer any insurance or billing questions from referring physicians and patients. Many years of combined experience in Dermatopathology coding and billing make our Billing Department staff experts in what they do.

Within the Billing Department, claims are filed to the appropriate insurance companies, and incoming materials are processed, posted, and double checked for accuracy. If we can determine that an insurance claim was misprocessed or denied in error by the patient’s insurer, we will follow up with the insurer before billing the patient, thereby saving the patient the time and aggravation of many insurance appeals. All patient statements and claims are carefully reviewed before being mailed.
