San Mateo County Health is seeking an experienced Medical Records Coder II/III to join Correctional Health and support the coding of CalAIM billable services, including clinic visits and ancillary services. This position plays an important role in ensuring accurate reimbursement while supporting continuity of care for justice-involved individuals.
The successful candidate will perform billing functions related to the Department of Health Care Services (DHCS) Justice-Involved CalAIM Initiative. This initiative allows eligible incarcerated individuals to enroll in Medi-Cal prior to their release and enables reimbursement for covered healthcare services provided during the 90 days before reentry, helping support successful transitions back into the community.
This position requires independent proficiency in ICD-10 and CPT coding, coding audits, physician education on coding practices, Evaluation and Management (E/M) coding, and identifying and resolving billing edits.
This assignment primarily focuses on professional fee (profee) coding, with the majority of work involving outpatient clinic visits. Additional assignments may include other professional fee chart types. A strong understanding of ICD-10/CPT coding guidelines, code combinations, and documentation requirements is essential for success.
Initial training will be provided onsite in the Health Information Management Department in San Mateo. Following training, the successful candidate will primarily work in the adult correctional facilities in Redwood City and/or the Youth Services Center in San Mateo. Remote work options may be available based on operational needs.
