Z46.2
Encounter for fitting and adjustment of other devices related to nervous system and special senses
Z46.2 (also written Z462) is a billable ICD-10-CM diagnosis code for encounter for fitting and adjustment of other devices related to nervous system and special senses. It is part of the FY2027 code set, effective October 1, 2026. It is one of the 12 codes in category Z46 (Encounter for fitting and adjustment of other devices). The Alphabetic Index lists it under 30 entries. Its coding notes include 1 Excludes1 entry and 6 Excludes2 entries.
Guidelines tip
From the FY2027 Official Guidelines. ICD10Ref adds no rules of its own.
Aftercare Z codes are not used when treatment is directed at a current, acute disease, or for aftercare of an injury. For an injury, the acute injury code with a 7th character for a subsequent encounter is used.
Excludes1
Not coded here. The listed conditions generally should not be reported together.
- malfunction or other complications of device - see Alphabetical Index
Excludes2
Not included here. Both codes may be reported if the patient has both conditions.
Also from chapter/block level (1 note)
- follow-up examination for medical surveillance after treatment (Z08-Z09)

Notes
Also from chapter/block level (3 notes)
- Z codes represent reasons for encounters. A corresponding procedure code must accompany a Z code if a procedure is performed. Categories Z00-Z99 are provided for occasions when circumstances other than a disease, injury or external cause classifiable to categories A00-Y89 are recorded as 'diagnoses' or 'problems'. This can arise in two main ways:
- (a) When a person who may or may not be sick encounters the health services for some specific purpose, such as to receive limited care or service for a current condition, to donate an organ or tissue, to receive prophylactic vaccination (immunization), or to discuss a problem which is in itself not a disease or injury.
- (b) When some circumstance or problem is present which influences the person's health status but is not in itself a current illness or injury.
