CMS Finalizing Principal Illness Navigation (PIN) Services

This is information from the 2024 Physician Fee Schedule Final Rule

https://public-inspection.federalregister.gov/2023-24184.pdf

CMS developed four HCPCS codes for Principal Illness Navigation. This service is intended to help patients with serious conditions navigate their health care treatment.

PIN services are incident-to services so may only be performed in a non-facility setting
Informed consent is required-the patient must agree to receive these services. Consent may be written or verbal, as long as it is documented in the record
An initiating visit is required (see below)
HCPCS codes: G0023, G0024, G0140, G0146
The navigator may be someone who has had the disease or condition being treated
