Z12.4

Encounter for screening for malignant neoplasm of cervix

BILLABLE STATUSYes
IMPLEMENTATION DATEOctober 1, 2015

Code Description

ICD-10 Z12.4 is a billable code used to indicate a diagnosis of encounter for screening for malignant neoplasm of cervix.

Key Diagnostic Point:

Z12.4 is used to indicate an encounter for screening for malignant neoplasm of the cervix, primarily cervical cancer. This screening is crucial for early detection, which significantly improves treatment outcomes. Factors influencing health status include access to healthcare, socioeconomic status, education, and cultural beliefs, which can affect a woman's likelihood of undergoing regular screenings. Preventive care, such as Pap smears and HPV testing, is essential in identifying precancerous changes in cervical cells. Social determinants of health, including lack of insurance, transportation issues, and health literacy, can hinder access to these screenings. Regular screening is recommended for women aged 21 to 65, and aftercare may involve follow-up visits based on screening results. Accurate coding of Z12.4 ensures proper tracking of preventive services and facilitates public health initiatives aimed at reducing cervical cancer incidence.

Coding Guidelines

Inclusion Criteria

Use Z12.4 When
  • Z codes are used when a patient is not currently ill but is receiving services for preventive care
  • 4 should be sequenced as the primary diagnosis when the encounter is solely for screening
  • Payer requirements may vary, so it is essential to verify coverage for preventive services

Frequently Asked Questions

What is the recommended age for cervical cancer screening?

The CDC recommends that women begin cervical cancer screening at age 21, with Pap smears every three years until age 29. From ages 30 to 65, women can choose to have a Pap smear alone every three years, or a Pap smear plus HPV testing every five years.
