Are ICD-10 codes related to product classification?

While not directly a product classification system like those used by the FDA, ICD-10 codes describe the conditions treated by or procedures performed with MedTech products. Adequate coding ensures proper identification of medical necessity and utilization.

What is the significance of the CMS ICD-10 Coordination & Maintenance meetings?

These public meetings are where new and revised ICD-10 codes are discussed and approved. For MedTech companies, these meetings represent a crucial opportunity to advocate for codes that accurately reflect their innovative technologies and ensure appropriate reimbursement.

Do other countries use ICD-10 codes?

Many countries use some form of ICD, which is maintained by the World Health Organization (WHO) for mortality and morbidity statistics. However, specific implementation and usage, such as for reimbursement, can vary significantly by country. ICD-10-CM and ICD-10-PCS are US-specific adaptations.

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 the regulation says

ICD-10-CM codes are used for reporting diagnoses across all healthcare settings, as mandated by the Health Insurance Portability and Accountability Act (HIPAA) for electronic transactions. ICD-10-PCS codes are specifically for reporting inpatient procedures and are critical for reimbursement under systems like Medicare Severity-Diagnostic Related Groups (MS-DRGs) in the United States, as managed by the Centers for Medicare and Medicaid Services (CMS). The correct application of these codes directly impacts billing, data collection, and public health reporting.

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.

Examples

A MedTech manufacturer develops a novel surgical implant; they must ensure that a corresponding ICD-10-PCS code exists or is proposed to ensure hospitals can bill for its use effectively.
A regulatory affairs specialist reviews clinical study data to identify diagnoses that will be reported using ICD-10-CM codes, verifying alignment with the intended use and claims for the device.
During post-market surveillance, ICD-10-CM codes associated with device complications or adverse events are analyzed to identify potential trends or issues.

Common pitfalls

•Assuming that a MedTech product automatically receives a unique ICD-10-PCS code without active engagement in the CMS coordination and maintenance process is a common mistake.
•Failing to understand the specific criteria and timelines for proposing new ICD-10 codes can lead to delayed market access or suboptimal reimbursement for new technologies.
•Incorrectly coding diagnoses (ICD-10-CM) or procedures (ICD-10-PCS) can result in claim denials, audits, and potential penalties.
•Overlooking the distinction between ICD-10-CM for diagnoses and ICD-10-PCS for inpatient procedures can lead to mischaracterization of a device’s impact or use.

Frequently asked questions

Regulatory professionals monitor the development of new ICD-10 codes, particularly ICD-10-PCS, to ensure that their MedTech products can be appropriately coded for reimbursement and data tracking. They may engage in the CMS coordination and maintenance process to advocate for new codes relevant to their devices.
