Encounter for prophylactic Rho(D) immune globulin

BILLABLE STATUSYes
IMPLEMENTATION DATEOctober 1, 2015

Code Description

ICD-10 Z29.13 is a billable code used to indicate a diagnosis of encounter for prophylactic rho(d) immune globulin.

Key Diagnostic Point:

Z29.13 is used to indicate an encounter for the administration of prophylactic Rho(D) immune globulin, a critical preventive measure for Rh-negative pregnant women. This immunoglobulin is administered to prevent Rh immunization, which can lead to hemolytic disease of the newborn in subsequent pregnancies. The administration of Rho(D) immune globulin is a preventive health service that addresses a significant social determinant of health, as it can impact maternal and infant health outcomes. Factors influencing the need for this intervention include access to prenatal care, education about Rh incompatibility, and socioeconomic status. Proper documentation of the encounter is essential to ensure appropriate coding and reimbursement, as well as to track the effectiveness of preventive measures in maternal health care.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Need for accurate patient history regarding Rh status
  • Documentation of the timing of administration in relation to pregnancy
  • Understanding of preventive care guidelines and protocols
  • Potential for co-existing conditions that may complicate coding

Audit Risk Factors

  • Inadequate documentation of patient history and Rh status
  • Failure to document the timing of the Rho(D) immune globulin administration
  • Incorrect coding due to misunderstanding of preventive care guidelines
  • Lack of supporting documentation for the encounter

Coding Guidelines

Inclusion Criteria

Use Z29.13 When
  • Z codes are used when a patient encounters health services for reasons other than a current illness or injury
  • 13 should be sequenced appropriately, often as a secondary code following a primary diagnosis related to pregnancy
  • Payer requirements may vary, so it is essential to verify coverage for preventive services
