Z31.82

Encounter for Rh incompatibility status

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

Code Description

ICD-10 Z31.82 is a billable code used to indicate a diagnosis of encounter for rh incompatibility status.

Key Diagnostic Point:

Z31.82 is used to indicate an encounter for patients who have a history of Rh incompatibility, which can pose significant risks during pregnancy. This code is crucial for preventive care, as it allows healthcare providers to monitor and manage potential complications associated with Rh incompatibility, such as hemolytic disease of the newborn. Social determinants of health, such as access to prenatal care, education about Rh incompatibility, and socioeconomic status, can influence health outcomes. Preventive measures include regular screenings and immunoglobulin administration to prevent sensitization. This code is also relevant in aftercare settings, where ongoing monitoring and education are essential for managing the health of both the mother and the newborn.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Requires understanding of maternal-fetal medicine and Rh incompatibility implications.
  • Documentation must include detailed patient history and current status.
  • Potential for multiple encounters leading to confusion in coding.
  • Need for accurate sequencing with other relevant codes.

Audit Risk Factors

  • Inadequate documentation of patient history related to Rh incompatibility.
  • Failure to document preventive measures taken during encounters.
  • Incorrect sequencing with other diagnosis codes.
  • Lack of clarity on the reason for the encounter.
