ICD-10 code for treatment refusal of

Within Z53.2, choose Z53.20 (because of patient's decision for unspecified reasons) only when documentation doesn't support a more specific option: due to patient leaving prior to being seen by health care provider (Z53.21) and because of patient's decision for other reasons (Z53.29).
