The rules that decide whether a claim pays
Coding is the part everyone studies and it is rarely what sinks a claim. The clauses below are: who was covered when, which plan goes first, which payer the case belonged to, and whether anyone wrote down why the treatment was necessary. All of them are knowable before treatment, and almost none of them are appealable afterwards.
By question
Most denials were decided before the claim was written
A frequency limit, a missing tooth clause, an exclusion or a coordination rule is a contract term. It is not a judgement about the treatment, it does not respond to a better narrative, and it will not be overturned on appeal. The work that changes the outcome happens at verification, days or weeks earlier, and it is mostly a matter of asking for dates.
Which is also why a practice with a strong coder and weak verification tends to have aging it cannot explain. The claims are correct. They were never going to be paid.
Next door to this
Why do dental claims get denied when the coding is correct?
Because most denials are not coding decisions. They are contract decisions made before the claim was written: a frequency limit, a missing tooth clause, a waiting period, an exclusion, or a coordination rule between two plans. Correct coding is necessary and it is not sufficient, which is why verification is worth more than a coding review for most practices.
What is the difference between a frequency limit and a missing tooth clause?
A frequency limit restricts how often a benefit can be used and runs from the date of the last procedure. A missing tooth clause excludes specific teeth permanently, based on whether they were already missing when coverage began. One expires and the other usually does not. They are routinely confused, and they require different responses.
When should a dental claim go to medical insurance instead?
When the case is about disease, injury or function rather than teeth. Trauma, pathology and biopsies, oral appliances for obstructive sleep apnoea, temporomandibular disorders, surgical extraction of impacted teeth causing pathology, and medically necessary general anaesthesia are the usual ones. Medical claims need a diagnosis code as well as a procedure code, which is why ICD-10 appears in a dental practice.
Does having two dental plans mean the patient pays nothing?
Often not. Under a non-duplication or maintenance of benefits contract the secondary plan pays only the amount by which its allowance exceeds what the primary already paid, which is frequently zero. Annual maximums do not combine either. The point to establish which kind of contract you are dealing with is verification, before treatment is presented.
What is the single most valuable thing to check before a large case?
The patient's history of dates. The last prosthesis, the extraction dates, the last restoration on that surface, the coverage effective date. Almost every expensive denial in prosthetics and major restorative is decided by one of those dates, and all of them are available before treatment for the cost of asking.
