About Z87.7

Z87.7 is the ICD-10-CM diagnosis code for personal history of (corrected) congenital malformations. It belongs to category Z87 (personal history of other diseases and conditions), 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 a header code, so it can't be reported by itself; one of its 7 subcodes must be used instead.

Within Z87 (personal history of other diseases and conditions), Z87.7 is specifically for personal history of (corrected) congenital malformations. Related codes cover diseases of the respiratory system (Z87.0), diseases of the digestive system (Z87.1), diseases of the skin and subcutaneous tissue (Z87.2), diseases of the musculoskeletal system and connective tissue (Z87.3), diseases of genitourinary system (Z87.4), complications of pregnancy, childbirth and the puerperium (Z87.5), certain (corrected) conditions arising in the perinatal period (Z87.6) and other specified conditions (Z87.8).

To report this condition, pick the subcode that matches the documentation: Z87.71 (of genitourinary system), Z87.72 (of nervous system and sense organs), Z87.73 (of digestive system), Z87.74 (of heart and circulatory system), Z87.75 (of respiratory system), Z87.76 (of integument, limbs and musculoskeletal system) and Z87.79 (malformations).

The conditions in its Excludes2 note aren't part of Z87.7, but may be coded alongside it if the patient has both: congenital malformations that have been partially corrected or repaired but which still require medical treatment - code to condition, other postprocedural states (Z98.-), personal history of medical treatment (Z92.-), presence of cardiac and vascular implants and grafts (Z95.-) and 3 more.

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