COBGC Coding Guidelines and Conventions 3 — Questions and Answers
Question 1: The global obstetric package (antepartum, delivery, postpartum) applies to which CPT code range?
- 59000–59076
- 59400–59430 (Correct answer)
- 59610–59622
- 59050–59076
Correct answer: 59400–59430
CPT codes 59400 (vaginal delivery) and 59510 (cesarean delivery) and their global counterparts (59400–59430) include routine antepartum care, delivery, and postpartum care as a bundled global package.
Question 2: When a provider other than the one who provided antepartum care performs the delivery, how should it be coded?
- Report the full global OB code with modifier 52
- Report only the delivery component code (e.g., 59409 or 59514) (Correct answer)
- Report the global code and add modifier 54
- Report both providers using split-bill codes
Correct answer: Report only the delivery component code (e.g., 59409 or 59514)
When the delivering provider did not furnish the antepartum care, only the delivery-only CPT code (such as 59409 for vaginal delivery only) should be reported.
Question 3: Which ICD-10-CM chapter contains the majority of codes used for obstetric conditions?
- Chapter 14 – Diseases of the genitourinary system
- Chapter 15 – Pregnancy, childbirth, and the puerperium (Correct answer)
- Chapter 16 – Certain conditions originating in the perinatal period
- Chapter 18 – Symptoms, signs and abnormal clinical findings
Correct answer: Chapter 15 – Pregnancy, childbirth, and the puerperium
Chapter 15 (O00–O9A) is the primary chapter for coding conditions related to pregnancy, childbirth, and the puerperium.
Question 4: Which modifier is appended to a CPT code to indicate that a procedure was performed bilaterally?
- Modifier 50 (Correct answer)
- Modifier 51
- Modifier 59
- Modifier 52
Correct answer: Modifier 50
Modifier 50 indicates that an identical procedure was performed on both sides of the body during the same operative session.
Question 5: Under ICD-10-CM guidelines, the postpartum period is defined as:
- The first 28 days following delivery
- The first 6 weeks (42 days) following delivery (Correct answer)
- The first 3 months following delivery
- The first 10 days following delivery
Correct answer: The first 6 weeks (42 days) following delivery
ICD-10-CM defines the postpartum (puerperium) period as the first 6 weeks (42 days) following delivery.
Question 6: A 'Code First' note in ICD-10-CM instructs the coder to:
- Assign the instructed code as an additional code only
- Sequence the instructed underlying condition code before the manifestation or etiology-specific code (Correct answer)
- Use only the manifestation code and omit the underlying code
- Query the physician before any code is assigned
Correct answer: Sequence the instructed underlying condition code before the manifestation or etiology-specific code
A 'Code First' instruction means the underlying condition or etiology must be sequenced as the principal/first-listed diagnosis before the code with the note.
Question 7: When coding an obstetric complication in ICD-10-CM, how should the episode of care be specified?
- Using the 5th character to indicate antepartum, childbirth, or postpartum
- Using the 7th character where applicable to identify the trimester or episode (Correct answer)
- By adding a note in the medical record rather than a code character
- Using a HCPCS modifier to denote the episode
Correct answer: Using the 7th character where applicable to identify the trimester or episode
Many ICD-10-CM Chapter 15 codes require a 7th character (or a specific character position) to identify whether the complication occurred antepartum, during childbirth, or postpartum.
