ICD-10 code for implanted device management

The ICD-10-CM code for implanted device management is Z45.9 (Encounter for adjustment and management of unspecified implanted device). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on Z45.9.

Within Z45, choose Z45.9 (unspecified implanted device) only when documentation doesn't support a more specific option: cardiac device (Z45.0), infusion pump (Z45.1), vascular access device (Z45.2), s of the special senses (Z45.3), implanted nervous system device (Z45.4) and other implanted devices (Z45.8).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 951 (Other Factors Influencing Health Status, relative weight 0.5577), in MDC 23 (Factors Influencing Health Status and Other Contacts with Health Services), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
