Molecular Pathology (MOPATH) Codes

The CPT Editorial Panel has approved the early release of the most recently approved molecular pathology codes. All published changes provided as an early release of these codes are not intended to take effect until the implementation date.


To assist users in reporting the most recently approved molecular pathology codes, the AMA’s CPT Web site features updates of the CPT Editorial Panel actions and early release of the Category III codes in July and January in a given CPT cycle. These dates for early release correspond with the three annual CPT Editorial Panel meetings for each CPT cycle (June, October, and February).

As for all other CPT codes, inclusion of a descriptor and its associated code number does not represent endorsement by the AMA of any particular diagnostic or therapeutic procedure or service. Inclusion or exclusion of a procedure or service does not imply any health insurance coverage or reimbursement policy.
