Z86 — Personal history of certain other diseases
Z86 is a non-billable header ICD-10-CM code for personal history of certain other diseases. It cannot be billed on its own: choose one of the more specific child codes below.
Code first
The underlying condition must be sequenced before this code.
- any follow-up examination after treatment (Z09)
Other codes that can never be billed with Z86
These codes carry an Excludes1 note pointing at Z86. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading Z86 alone.
- I27.82Chronic pulmonary embolism
- I69Sequelae of cerebrovascular disease
- I82.7Chronic embolism and thrombosis of veins of upper extremity
- Z87.41Personal history of dysplasia of the female genital tract
- Z87.820Personal history of traumatic brain injury
- I82.5Chronic embolism and thrombosis of deep veins of lower extremity
Risk adjustment
Z86 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
The condition this code belongs to
Every code for the condition on one page, which one applies when, and the mistake coders make with it.
