Range Overview
The ICD-10 category Q30-Q38 pertains to congenital malformations of the respiratory system. These codes are used to document congenital anomalies, such as malformations of the nose, larynx, trachea, bronchus, lung, and other parts of the respiratory system. They also cover congenital malformations of the circulatory system, including those of the heart, arteries, veins, and other vessels.
Key Usage Points:
- •Use these codes for congenital malformations diagnosed at any age, not just in infants or children.
- •Always code to the highest level of specificity, using additional characters if available.
- •Use additional codes to identify any associated conditions or complications.
- •Remember that these codes are not used for acquired conditions or diseases of the respiratory or circulatory systems.
- •When coding for congenital malformations of the heart, be sure to specify the exact type of malformation.
Coding Guidelines
When to Use:
- ✓When a patient is diagnosed with a congenital malformation of the respiratory or circulatory system.
- ✓When a congenital malformation is the cause of a patient's symptoms or condition.
- ✓When a congenital malformation is discovered during a routine physical examination.
- ✓When a congenital malformation is found during a diagnostic imaging procedure.
When NOT to Use:
- ✗When a patient has an acquired disease or condition of the respiratory or circulatory system.
- ✗When a patient has a temporary or reversible condition of the respiratory or circulatory system.
- ✗When a patient has a condition that is not related to a congenital malformation.
- ✗When a patient's condition is due to an injury or trauma.
Code Exclusions
Always verify exclusions with the latest version of the ICD-10-CM Official Guidelines for Coding and Reporting.
Documentation Requirements
Proper documentation for these codes should include a detailed description of the congenital malformation, its location, and any associated conditions or complications. The patient's medical history, physical examination findings, and diagnostic test results should also be documented.
Clinical Information:
- •Detailed description of the congenital malformation
- •Location of the malformation
- •Associated conditions or complications
- •Patient's medical history
- •Physical examination findings
Supporting Evidence:
- •Diagnostic imaging reports
- •Laboratory test results
- •Operative reports
- •Consultation notes
Good Documentation Example:
Patient has a congenital malformation of the heart, specifically a ventricular septal defect. This was confirmed by echocardiogram.
Poor Documentation Example:
Patient has a heart defect.
Common Documentation Errors:
- âš Not documenting the specific type of congenital malformation
- âš Not including the location of the malformation
- âš Not providing supporting evidence from diagnostic tests
- âš Not documenting associated conditions or complications
Range Statistics
Coding Complexity
These codes have a medium complexity rating because they require a detailed understanding of the anatomy and physiology of the respiratory and circulatory systems, as well as the ability to distinguish between congenital and acquired conditions. They also require the ability to code to the highest level of specificity and to use additional codes for associated conditions or complications.
Key Factors:
- â–¸The need to code to the highest level of specificity
- â–¸The need to use additional codes for associated conditions or complications
- â–¸The need to distinguish between congenital and acquired conditions
- â–¸The need to verify exclusions
Specialty Focus
These codes are primarily used by pediatricians, cardiologists, pulmonologists, and other specialists who diagnose and treat congenital malformations of the respiratory and circulatory systems.
Primary Specialties:
Clinical Scenarios:
- • A newborn is diagnosed with a congenital diaphragmatic hernia.
- • A child is found to have a patent ductus arteriosus during a routine physical examination.
- • A teenager is diagnosed with a congenital malformation of the nose after complaining of chronic nasal congestion.
- • An adult is found to have a congenital malformation of the lung during a diagnostic imaging procedure for an unrelated condition.

Frequently Asked Questions
Can these codes be used for acquired diseases or conditions of the respiratory or circulatory systems?
No, these codes are only used for congenital malformations. Acquired diseases or conditions should be coded with the appropriate codes from other sections of the ICD-10.
