Z86.005Personal history of in-situ neoplasm of middle ear and respiratory system

Z86.005 is the ICD-10-CM diagnosis code for personal history of in-situ neoplasm of middle ear and respiratory system. It belongs to category Z86 (personal history of certain other diseases), block Z77-Z99 (persons with potential health hazards related to family and personal history and certain conditions influencing health status) and chapter 21 (factors influencing health status and contact with health services). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within Z86.00 (personal history of in-situ neoplasm), Z86.005 is specifically for personal history of in-situ neoplasm of middle ear and respiratory system. Related codes cover of breast (Z86.000), of cervix uteri (Z86.001), of other and unspecified genital organs (Z86.002), of oral cavity, esophagus and stomach (Z86.003), of other and unspecified digestive organs (Z86.004), melanoma in-situ (Z86.006), of skin (Z86.007), of other site (Z86.008) and 1 more.

Code first: any follow-up examination after treatment (Z09).

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.

It is not acceptable as the principal diagnosis for an inpatient stay; it may be reported as a secondary diagnosis.

It is exempt from present-on-admission (POA) reporting, so no POA indicator is required.

It was added in FY2020, effective October 1, 2019.
