Understanding Newborn Jaundice
Newborn jaundice manifests as a yellowish discoloration of a baby's skin and the sclerae (the whites of the eyes). It results from elevated levels of bilirubin—a yellow pigment produced during the normal breakdown of red blood cells. In most cases, neonatal jaundice is benign and resolves spontaneously, but in some instances, high bilirubin levels can lead to serious complications such as kernicterus, a form of brain damage.
What Causes Newborn Jaundice?
The causes of neonatal jaundice can be broadly categorized into physiological, pathological, and other less common factors:
1. Physiological Jaundice:
- Occurs in 60% of term and 80% of preterm infants.
- Results from immature liver function and increased bilirubin production.
- Typically appears 2-3 days after birth and resolves within a week.
2. Pathological Jaundice:
- Appears within the first 24 hours of life.
- Due to underlying conditions such as hemolytic disease, infections, or metabolic disorders.
3. Other Causes:
- Breastfeeding jaundice.
- Breast milk jaundice.
- Hemolytic disease of the newborn due to blood group incompatibilities.

ICD-10 Coding for Newborn Jaundice
The International Classification of Diseases, 10th Revision (ICD-10), provides specific codes to classify and document neonatal jaundice accurately. Correct coding reflects the true clinical picture and ensures appropriate management and reimbursement.
Primary ICD-10 Codes for Neonatal Jaundice
- P55.0 — Neonatal jaundice due to pre-existing isoimmunization
- P55.1 — Neonatal jaundice due to other specified hemolytic disease
- P59.0 — Neonatal jaundice due to physiologic jaundice of newborn
- P59.1 — Neonatal jaundice due to breast milk jaundice
- P59.8 — Other specified neonatal jaundice
- P59.9 — Neonatal jaundice, unspecified
Coding Based on Etiology and Timing
While some codes specify the cause, others are more general, especially when the etiology is unknown or unspecified. Accurate documentation by clinicians helps in selecting the most precise code.

Detailed Breakdown of Relevant ICD-10 Codes
P59.0 — Neonatal Jaundice Due to Physiologic Jaundice of Newborn
This code applies when the jaundice is considered a normal adaptation after birth. It generally appears between days 2 and 3 and resolves within a week in term infants. It is the most common type and does not indicate underlying pathology.
Key features:
- Onset: 2-3 days post-birth
- Duration: up to one week
- Cause: immature liver enzyme activity
P59.1 — Neonatal Jaundice Due to Breast Milk Jaundice
Breast milk jaundice is a benign condition that can persist longer than physiologic jaundice, often lasting beyond 2 weeks. It is thought to be related to substances in breast milk that inhibit bilirubin conjugation.
Features:
- Onset: after the first week
- Duration: may last several weeks
- Clinical considerations: usually no need for treatment unless bilirubin levels are dangerously high
P55 Series — Jaundice Due to Hemolytic Disease
Codes in this series are used when jaundice results from hemolytic conditions such as Rh or ABO incompatibility:
- P55.0 — Neonatal jaundice due to pre-existing isoimmunization
- P55.1 — Other specified hemolytic disease
Important points:
- These conditions require specific laboratory confirmation.
- They often necessitate interventions like phototherapy or exchange transfusion.
P59.8 and P59.9 — Other and Unspecified Neonatal Jaundice
These codes are used when the cause is not specified or falls outside the common categories. They are useful in cases where documentation does not clearly indicate the etiology.

Clinical Considerations for Coding
Accurate ICD-10 coding for neonatal jaundice depends on careful clinical documentation. Providers should include details about:
- Onset and duration of jaundice
- Underlying cause or suspected etiology
- Severity and bilirubin levels
- Any complications or treatments administered
Proper documentation ensures that the selected code correctly reflects the clinical scenario, which is vital for quality reporting, research, and reimbursement.
Common Pitfalls in Coding
- Using unspecified codes when specific etiology is known.
- Overlooking the timing of jaundice onset.
- Failing to document severity or complications, which might influence coding choices.

Related Conditions and Additional Codes
In some cases, neonatal jaundice may be associated with other conditions, requiring additional coding:
- P70.0 — Neonatal jaundice associated with hemolytic disease of the newborn
- P76.0 — Neonatal hyperbilirubinemia due to kernicterus
- O99.81 — Maternal-fetal blood group incompatibility affecting fetus and newborn
Including these codes can provide a comprehensive picture of the neonatal condition.

Importance of Proper Coding and Documentation
Accurate coding of neonatal jaundice is essential for multiple reasons:
- Quality of Care: Helps in monitoring disease prevalence and outcomes.
- Billing and Reimbursement: Ensures appropriate compensation for services rendered.
- Research and Public Health: Facilitates data collection for epidemiological studies.
- Legal and Compliance: Meets coding standards and legal requirements.
Healthcare providers should stay current with ICD-10 updates and guidelines to ensure compliance.

Conclusion
The ICD-10 coding system provides a structured and detailed approach to classifying newborn jaundice. Understanding the nuances of each code—ranging from physiological jaundice to complex hemolytic conditions—enables clinicians and medical coders to document cases accurately. Proper coding not only supports effective clinical management but also plays a pivotal role in public health surveillance, research, and healthcare reimbursement.
In summary, key ICD-10 codes for newborn jaundice include:
- P59.0 for physiological jaundice
- P59.1 for breast milk jaundice
- P55.0 and P55.1 for hemolytic disease-related jaundice
- P59.8 and P59.9 for other or unspecified causes
By ensuring precise documentation and coding, healthcare systems can better serve neonatal populations, improve outcomes, and advance neonatal health research.

Frequently Asked Questions
What is the ICD-10 code for newborn jaundice?
The ICD-10 code for neonatal jaundice is P59.0, which covers jaundice of newborn, including both physiological and pathological types.
How is neonatal jaundice classified in ICD-10?
In ICD-10, neonatal jaundice is classified under code P59.0, with further subcategories for specific causes such as hemolytic disease (P59.1) or other specified causes.
Why is accurate coding of newborn jaundice important in ICD-10?
Accurate ICD-10 coding for newborn jaundice ensures proper documentation for treatment, billing, and epidemiological tracking, facilitating better patient care and health statistics.
Are there other ICD-10 codes related to neonatal hyperbilirubinemia?
Yes, other related codes include P59.1 for hemolytic jaundice of the newborn and P59.9 for neonatal jaundice, unspecified.
How does ICD-10 distinguish between physiological and pathological jaundice in newborns?
ICD-10 primarily uses the code P59.0 for neonatal jaundice generally, but clinicians should specify the cause in the medical record; coding may reflect specific causes like P59.1 for hemolytic jaundice.
