Maternal Care for Breech Presentation: ICD-10-CM Coding Guidelines

Fetal positioning is a crucial aspect of late-term pregnancy and delivery. While most fetuses naturally assume a head-down (vertex) position by the third trimester, preparing for vaginal delivery, deviations from this optimal positioning, known as malpresentation or malposition, can complicate labor and delivery. Accurate coding of these conditions is essential for proper medical billing, statistical tracking, and reflecting the complexity of maternal care. This article provides a comprehensive guide to understanding and applying ICD-10-CM coding guidelines for maternal care related to breech presentation, a common type of fetal malpresentation.

Understanding Fetal Presentation, Position, and Lie

Before diving into coding specifics, it’s important to clarify the key terms that describe fetal orientation within the uterus:

Fetal Presentation: This refers to the part of the fetus that is closest to the cervix and will enter the pelvic inlet first. Common presentations include vertex (head), breech (buttocks or feet), and shoulder.
Fetal Position: This describes the location of a specific reference point on the presenting part of the fetus in relation to the maternal pelvis. For vertex presentations, the occiput (back of the head) is the reference point. Position indicates whether the fetus is facing anteriorly (towards the mother’s abdomen), posteriorly (towards the mother’s spine), or transversely (sideways).
Fetal Lie: This describes the orientation of the long axis of the fetus (spinal column) in relation to the long axis of the uterus. The lie can be longitudinal (parallel), transverse (perpendicular), or oblique (diagonal).

Optimal conditions for vaginal delivery involve a vertex presentation, occiput anterior position, and longitudinal lie.

Malpresentation and Malposition Defined

Malpresentation and malposition occur when the fetal presentation, position, or lie deviates from the normal parameters for vaginal delivery. Breech presentation, the focus of this article, is a significant type of malpresentation.

Types of Malpresentation:

Breech Presentation: In breech presentation, the buttocks and/or feet are the presenting parts. There are several types of breech presentations:
- Frank Breech: Buttocks are presenting, with legs extended straight up towards the head.
- Complete Breech: Buttocks are presenting, with hips and knees flexed (baby in a seated position).
- Incomplete Breech: One or both hips are extended, and one or both feet are presenting below the buttocks.
- Footling Breech: One or both feet are the presenting part, below the buttocks.
Face, Brow, or Chin Presentation: These occur when the fetal neck is hyperextended, causing the face, brow, or chin to be the presenting part.
Shoulder Presentation: The shoulder is the presenting part.
High Head at Term: The fetal head remains high in the pelvis and does not engage.
Compound Presentation: A fetal extremity (hand or arm) presents alongside the presenting part (usually the head).

Types of Malposition:

Occiput Posterior: The fetal occiput is directed towards the mother’s posterior pelvis (spine), and the fetus faces the mother’s abdomen (“sunny-side up”).
Occiput Transverse: The fetal occiput is directed towards the side of the mother’s pelvis.

Abnormal Lie:

Oblique Lie: The fetus is positioned diagonally in the uterus.
Transverse Lie: The fetus is positioned sideways in the uterus.
Unstable Lie: The fetal lie changes frequently after 36 weeks of gestation.

ICD-10-CM Coding for Breech Presentation and Other Malpresentations: Category O32

ICD-10-CM category O32, Maternal care for malpresentation of fetus, is specifically designated for coding maternal care related to fetal malpresentation and malposition. It’s crucial to understand the specific codes within this category and their application based on documentation.

Key Codes within Category O32:

O32.0 Maternal care for unstable lie
O32.1 Maternal care for breech presentation
- This code encompasses:
  - Maternal care for buttocks presentation
  - Maternal care for complete breech
  - Maternal care for frank breech
- Excludes 1: footling presentation (O32.8); incomplete breech (O32.8) (This is an important distinction, as footling and incomplete breech are coded differently).
O32.2 Maternal care for transverse and oblique lie
- Includes:
  - Maternal care for oblique presentation
  - Maternal care for transverse presentation
O32.3 Maternal care for face, brow and chin presentation
O32.4 Maternal care for high head at term
- Includes:
  - Maternal care for failure of head to enter pelvic brim
O32.6 Maternal care for compound presentation
O32.8 Maternal care for other malpresentation of fetus
- This code is used for:
  - Maternal care for footling presentation
  - Maternal care for incomplete breech
O32.9 Maternal care for malpresentation of fetus, unspecified

Navigating the Alphabetic Index and Tabular List:

Accurate code selection relies on using both the Alphabetic Index and the Tabular List in ICD-10-CM.

Alphabetic Index Search Examples:

To find the code for breech presentation, you can search under:
- “Delivery cesarean (for) breech presentation” which leads to O32.1
- “Delivery complicated by malposition, malpresentation without obstruction breech” which also leads to O32.1
- “Breech presentation (mother)” which directly points to O32.1
For other malpresentations, similar searches can be performed using terms like “face presentation,” “transverse lie,” etc.

Tabular List Guidance for Category O32:

The Tabular List provides essential notes for category O32:

“Codes from this category are assigned when malpresentation/malposition is the reason for maternal care.” This emphasizes that the malpresentation must be clinically significant and require maternal care for code assignment.
“When malpresentation causes obstructed labor, a code from category O64 is assigned rather than from category O32.” This is a critical distinction. If malpresentation leads to obstructed labor, the coding shifts to category O64 (Obstructed labor due to malposition and malpresentation of fetus).
“A 7th character that reports the affected fetus is assigned to codes for malpresentation/malposition.” ICD-10-CM codes in category O32 require a 7th character to specify the fetus affected in multiple gestations.

7th Character Options for Category O32:

0 – not applicable or unspecified (for single gestations or when the fetus is unspecified in multiple gestations)
1 – fetus 1
2 – fetus 2
3 – fetus 3
4 – fetus 4
5 – fetus 5
9 – other fetus

Placeholder “X”: Because category O32 codes are four characters long, placeholders “X” are used in the 5th and 6th positions to correctly place the 7th character. For example, O32.1XX0 for maternal care for breech presentation, fetus unspecified in a singleton pregnancy.

ICD-10-CM Official Guidelines and Breech Presentation Coding

The ICD-10-CM Official Guidelines for Coding and Reporting provide further direction on sequencing and application of O32 codes. Guideline I.C.15.b.4 Selection of OB Principal or First-listed Diagnosis When a Delivery Occurs is particularly relevant.

Key Guideline Points:

Principal Diagnosis: Malpresentation/malposition (like breech presentation) is sequenced as the principal diagnosis when:
- It is the reason for admission.
- It and another condition prompt admission, but the malpresentation is most related to the delivery (e.g., leading to cesarean section or instrumental vaginal delivery).
- A patient admitted without pregnancy complications develops malpresentation post-admission, and it necessitates maternal care (repositioning, version, instrumental delivery, etc.).
Malpresentation without Maternal Care: If a malpresentation exists but does not require specific maternal care, a code from category O32 is not assigned. The guidelines emphasize “clinically significant conditions that affect patient care.”

Example Scenario (No O32 Code): A preterm infant delivers vaginally in the occiput posterior position (sunny-side up). Because the malposition did not necessitate any specific maternal care or intervention beyond routine delivery management, an O32 code is not assigned.

Breech Presentation as Indication for Cesarean Section

Breech presentation is a frequent indication for cesarean delivery. When vaginal delivery is contraindicated due to breech presentation, a cesarean section may be performed for the safety of both mother and fetus.

Category O32 “Includes” Note and Cesarean Delivery:

The “Includes” note under category O32 is crucial for coding cesarean sections related to malpresentation:

“Includes: the listed conditions as a reason for observation, hospitalization or other obstetric care of the mother, or for cesarean delivery before onset of labor”

This note specifies that O32 codes are appropriate when the decision for cesarean delivery due to malpresentation (including breech) is made before the onset of labor.

Distinction from Obstructed Labor (Category O64):

If a patient presents in labor intending for vaginal delivery, and breech presentation (or another malpresentation) leads to obstructed labor and then necessitates a cesarean section, the coding shifts to category O64, Obstructed labor due to malposition and malpresentation of fetus, not O32.

In summary:

Cesarean before labor due to breech: Code O32.1 (Maternal care for breech presentation)
Cesarean during labor due to breech leading to obstruction: Code from category O64 (Obstructed labor due to malposition and malpresentation of fetus).

Conclusion: Accurate Coding for Maternal Care in Breech Presentation

Accurate ICD-10-CM coding for maternal care related to breech presentation is essential for healthcare providers, coders, and billing specialists. Understanding the definitions of fetal presentation, position, and lie, as well as the nuances of category O32 and related coding guidelines, is crucial.

Key Takeaways for Coding Breech Presentation and Malpresentations:

Clinical Significance: Category O32 codes are assigned only when the malpresentation necessitates maternal care.
Index and Tabular List: Utilize both the Alphabetic Index and Tabular List for accurate code selection.
7th Character: Remember the required 7th character for fetus designation, especially in multiple gestations.
Obstructed Labor vs. Care Before Labor: Differentiate between cesarean deliveries performed before labor due to malpresentation (O32) and those performed during labor due to malpresentation causing obstruction (O64).
Coding Clinic Guidance: For further clarification and specific scenarios, consult official coding resources like Coding Clinic published by the American Hospital Association (AHA) for authoritative guidance on complex obstetric coding situations.

By adhering to these guidelines and seeking authoritative resources when needed, healthcare professionals can ensure accurate and compliant coding for maternal care related to breech presentation and other fetal malpresentations.
