The billing rules behind most denials, in plain words
Short guides for practice owners and billers. Each one covers a rule that payers deny claims over, and what to put on the claim instead.
Psychotherapy codes payers won't pay together
Most therapy claim denials aren't about whether therapy happened. They're about which codes went on the claim together. Here are the pairings that cause them.
Modifier 25: when a same-day office visit gets paid
A patient comes in for one problem and leaves with a procedure. Whether the office visit gets paid as well comes down to one modifier and what your note shows.
Medicare chiropractic claims: the AT modifier and what Medicare won't pay
Medicare pays chiropractors for one thing, and only while treatment is improving the patient's condition. Getting that right on the claim is most of the work.
GP, GO and GN: the Medicare therapy modifiers, and why a missing one costs you
Every outpatient therapy line on a Medicare claim says which kind of therapy it was. Leave that off and the line is denied, however good the care was.
