    ICD-10-CM / ICD-10-PCS

    Diagnosis (CM) and inpatient procedure (PCS) coding systems used in U.S. claims.

    Reviewed by Christian Espinosa, Founder, Blue Goat CyberLast reviewed May 5, 2026

    Definition

    ICD-10-CM codes are diagnosis codes used across all care settings; ICD-10-PCS codes describe inpatient procedures and drive MS-DRG assignment for hospital reimbursement.

    What this means in practice

    Securing a unique ICD-10-PCS code can materially change inpatient payment for a new procedure or device. CMS holds public ICD-10 Coordination & Maintenance meetings twice yearly.
