Personal history of certain other diseases (Z86) ICD-10-CM
The Z86 code range covers personal history of certain other diseases with 51 ICD-10-CM diagnosis codes. 40 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.
Code First
Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions, the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists, there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation.

About the Z86 Code Range
A person's history may include growths, infections, or diseases affecting different body systems. This category groups those histories by the kind of condition involved.
Z86.0 separates in-situ, benign, and uncertain-behavior growths. Its subdivisions distinguish sites and, for a history of colon polyps, polyp types. Z86.1 groups infectious and parasitic diseases by the named disease. Z86.2 addresses blood and immune-related disorders; Z86.3 addresses endocrine, nutritional, and metabolic diseases.
Z86.5 groups mental and behavioral disorders, while Z86.6 groups nervous system and sense organ diseases. Z86.7 groups circulatory diseases, with subdivisions for conditions such as pulmonary embolism, thrombophlebitis, and sudden cardiac arrest.
FY 2027 changes: The FY 2027 ICD-10-CM update, effective October 1, 2026, added Z86.17.
