Update: Crown Prior Authorization (PA) Exception for Endodontic Therapy

On October 19, 2022, the Office of MaineCare Services (OMS) issued a bulletin informing providers that MaineCare will no longer require a PA for crowns provided in conjunction with endodontic therapy when a qualifying diagnosis was included on the dental claim. The list of qualifying diagnosis inadvertently listed ICD-10-CM code K04.0-Pulpitis. Official guidance issued by the American Academy of Professional Coders (AAPC) requires the use of a 5th digit when ICD-10-CM code K04.0 is used. Please reference the chart below for qualifying diagnosis codes and descriptions. 

Qualifying Diagnosis Code 

Diagnosis Code Description 

K02.53 

Dental caries on pit and fissure surface penetrating into pulp 

K02.63 

Dental caries on smooth surface penetrating into pulp 

K04.01
