(2023) CPT Code G0463 – Description, Guidelines, Reimbursement, Modifiers & Examples

CPT code G0463 will be reported by the physician when service renders at the hospital outpatient clinic visit for assessment and management of a patient.


In 2014, CMS proposed three new HCPCS G codes in OPPS (Outpatient Prospective Payment System) to substitute for five levels of evaluation and management settings.

It includes one G code for type A ED (Emergency Dept) visits and one for type B ED visits.

The new HCPCS code G0463 is an alternative to all clinic visits for new and established patients when billed to Medicare carriers.

G0463 is effective from January 1, 2014, in the place of Clinic visits codes (99201-99215).

The hospital requires to place only one G code instead of CPT (99201-99215) when billed to Medicare insurances. G0463 does not differentiate between new and established patients.

There are two types of charges as one is billed under facility or hospital charge while the other is physician charge.

G code is only used for hospital or facility-based payments when billed to Medicare under the OPPS.

Therefore, it eradicates the criteria of choosing level evaluation and management visits.

Also, it does not require any specific measures to meet for the service provided.
