About coding functional implant presence
The ICD-10-CM code for functional implant presence is Z96.9 (Presence of functional implant, unspecified). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on Z96.9.
Within Z96, choose Z96.9 (functional implant, unspecified) only when documentation doesn't support a more specific option: urogenital implants (Z96.0), intraocular lens (Z96.1), otological and audiological implants (Z96.2), artificial larynx (Z96.3), endocrine implants (Z96.4), tooth-root and mandibular implants (Z96.5), orthopedic joint implants (Z96.6), other bone and tendon implants (Z96.7) and 1 more.
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 008 (Simultaneous Pancreas, Islet Cell and Kidney Transplant, relative weight 5.5146), DRG 019 (Simultaneous Pancreas, Islet Cell and Kidney Transplant with Hemodialysis, relative weight 7.5493) and DRG 951 (Other Factors Influencing Health Status, relative weight 0.5577), in Pre-MDC and 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.
