About coding device removal

The ICD-10-CM code for device removal is Z46.9 (Encounter for fitting and adjustment of unspecified device). The official index lists 4 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on Z46.9.

Within Z46, choose Z46.9 (unspecified device) only when documentation doesn't support a more specific option: spectacles and contact lenses (Z46.0), hearing aid (Z46.1), related to nervous system and special senses (Z46.2), dental prosthetic device (Z46.3), orthodontic device (Z46.4), other gastrointestinal appliance and device (Z46.5), urinary device (Z46.6) and other specified devices (Z46.8).

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.
