Encounter for screening for depression

BILLABLE STATUSYes
IMPLEMENTATION DATEOctober 1, 2015
LAST UPDATED09/12/2025

Code Description

ICD-10 Z13.31 is a billable code used to indicate a diagnosis of encounter for screening for depression.

Key Diagnostic Point:

Z13.31 is used to indicate an encounter for screening for depression, a critical preventive measure in healthcare. This code is applicable when patients are assessed for depressive disorders, which can significantly impact overall health and quality of life. Screening for depression is essential in various settings, including primary care, mental health, and public health, as it helps identify individuals who may require further evaluation or treatment. Social determinants of health, such as socioeconomic status, education, and access to healthcare, play a crucial role in the prevalence and management of depression. Preventive care through screening can lead to early intervention, reducing the burden of mental health disorders on individuals and healthcare systems. Proper documentation of the screening process, including the tools used and results, is vital for accurate coding and reimbursement.
