question

Outcome of Delivery

answer

Code from category Z37 is assigned as additional code whenever patient delivers in the hospital. Fourth characters indicate outcome of delivery: Single or multiple Liveborn or stillborn For multiple births (more than twins), additional characters indicate the number of outcomes (e.g., triplets, quadruplets. For example, liveborn, some liveborn, or all stillborn: Used only on the mother's record. Not used for the newborn record. Do not assign codes from category Z37 when delivery occurs outside the hospital prior to admission.

question

Fetal Seventh Characters

answer

Some obstetric subcategory codes require a seventh character to identify the fetus for which the complication code applies. Seventh characters "1" through "9" apply in cases of multiple gestations to identify the fetus for which the code applies. Seventh character "0" (not applicable or unspecified) only used for the following situations: Single gestations When the documentation is insufficient to determine the fetus affected and it is not possible to obtain clarification Clinically impossible to determine which fetus is affected

question

Fetal Seventh Characters

answer

Assign codes in category O30, Multiple gestation, when using a seventh character of "1" through "9." Review the Tabular List for assignment of the correct seventh character for multiple gestations. Some providers refer to each fetus by alphabetical characters (e.g., fetus A, fetus B, etc.) Fetus A equated to fetus 1. Fetus B equated to fetus 2, etc. No expectation that the same fetus number or alphabetical character be consistently carried over from one admission to another. Identification of the fetus is based on provider documentation.

question

Selection of Principal Diagnosis

answer

For cesarean delivery, the principal diagnosis is the condition established after study responsible for the admission. If admitted with a condition that resulted in a cesarean, that condition is the principal diagnosis. If the reason for encounter is unrelated to the condition resulting in the cesarean delivery, the condition related to the reason for the encounter is selected as the principal diagnosis, even if a cesarean was performed.

question

Supervision of pregnancy with history of in utero procedure during previous pregnancy

answer

Assign code O09.82

question

Pre-existing Conditions

answer

Some conditions complicate or aggravate the pregnancy. Categories in chapter 15 of ICD-10-CM distinguish between pre-existing conditions and those occurring as a result of pregnancy. When assigning codes from chapter 15, determine whether a condition was pre-existing or developed due to the pregnancy. Categories not distinguishing between pre-existing or pregnancy-related conditions may be used for either. It is acceptable to use puerperium codes with codes complicating pregnancy and childbirth if a condition develops postpartum during the delivery episode.

Sequelae includes: Late effects occurring any time after the postpartum period. Code O94 is sequenced after the code describing the residual condition.

question

Obstetrical Procedures

answer

Obstetrical procedures in ICD-10-PCS distinguish between procedures performed on the fetus or the pregnant female. Procedures performed on the fetus (products of conception) are classified to the Obstetrics Section. Procedures performed on the pregnant female (other than the products of conception) are coded to the appropriate root operation in the Medical and Surgical Section. The body system (character 2) is always "pregnancy." There are three values used for body part: "products of conception" (0); "products of conception, retained" (1); and "products of conception, ectopic" (2).

question

Obstetrical Procedures

answer

Two root operations are unique to the Obstetrics Section: Abortion: Artificially terminating a pregnancy Delivery: Assisting the passage of the products of conception from the genital tract Applies only to manually assisted, vaginal delivery. Obstetrics Section, root operation "Extraction," used for: Cesarean deliveries Vaginal deliveries requiring forceps, vacuum, or internal version Procedures following delivery or abortion, such as: Curettage or evacuation of retained products of conception (body part "products of conception, retained")

question

Obstetrical Procedures

answer

Diagnostic or therapeutic dilation and curettage performed during times other than the postpartum or post-abortion period: Coded in the Medical and Surgical Section to the root operation "Extraction" and the body part "endometrium."

question

Procedures Assisting Delivery

answer

Labor induction by artificial rupture of membranes: Medical and Surgical Section, root operation "Drainage," body part "amniotic fluid," or By other surgical induction (cervical dilatation). Amnioinfusion: Administration Section, root operation "Introduction" Prophylactic treatment of oligohydramnios Reduction of variable decelerations of the fetal heart rate Treatment of preterm premature rupture of membranes

question

Forceps and Vacuum Extraction

answer

Forceps assist delivery Coded to the Obstetrics Section, root operation "extraction" Low-forceps delivery (7th-character qualifier value "3") Mid-forceps (7th-character qualifier value "4") High forceps (7th-character qualifier value "5") Breech presentations require: Partial or total breech extraction, with or without forceps to the aftercoming head Vacuum extraction (7th-character qualifier value "6") uses a traction device rather than forceps.

question

Episiotomy and Perineal Laceration

answer

Episiotomy is a surgical incision in the perineum, enlarging the vaginal opening to assist delivery. Episiorraphy (repair) is not coded separately. Repair is integral to the procedure. Episiotomy with forceps delivery requires two codes: Code forceps delivery as well as the episiotomy. For perineal lacerations classified as first, second, third, or fourth degree, assign category O70 codes. An episiotomy can extend to become a perineal laceration or tear. Assign a code for the episiotomy, along with a code for repair of perineal laceration.

question

Cesarean Delivery

answer

Operative delivery is carried out when, for some reason, spontaneous delivery is not possible or advisable. Cesarean sections are classified to the root operation "Extraction," body part "products of conception," and open approach. Extraperitoneal cesarean section is identified with seventh-character qualifier value "2."

question

Contraceptive Management

answer

Category Z30 describes encounters for the purpose of contraceptive management. Codes in this category cover the following services: Initiation of oral contraceptive measures (Z30.011); Counseling in natural family planning to avoid pregnancy (Z30.02); Insertion of intrauterine contraceptive device (Z30.430); Removal of intrauterine contraceptive device (Z30.432); Removal and reinsertion of intrauterine contraceptive device (Z30.433); Sterilization (Z30.2); and Surveillance of injectable contraceptive (Z30.42)

question

Contraceptive Sterilization

answer

Assign code Z30.2 for encounters for the purpose of contraceptive sterilization. Assign also codes for any underlying medical or psychological conditions, if applicable. If elective sterilization is performed during hospital episode for obstetrical delivery, assign code Z30.2 as an additional code along with a chapter 15 code. Assign code Z30.2 for both female and male sterilization. Sterilization is also referred to as tubal ligation: Surgical procedure to cut fallopian tubes, or coagulated, clipped (e.g., Filshie clip), cauterized, or blocked with an external ring (e.g., Falope ring) Root operations "Occlusion," "Excision," or "Destruction"

question

Contraceptive Sterilization

answer

Sterilization procedures for males are classified to the male reproductive system, root operations "Destruction" or "Excision." Code Z30.2 is not assigned when sterilization results from other treatment; or When a sterilization procedure is performed as part of the treatment for another condition. Assign codes for the original condition, any complications or comorbidities, and code the procedures as well. Sterilization procedures are usually permanent. However, reversal of the sterilization procedure is coded Z31.0, Encounter for reversal of previous sterilization.

question

Procreative management

answer

Assign category Z31, Encounter for procreative management, for patients having difficulty becoming pregnant. Assign code Z31.61 for encounters for procreative counseling and advice using natural family planning. Use code Z31.62, Encounter for fertility preservation counseling, to describe encounters for advice and counseling on available options to conceive a child or maintain pregnancy before the start of cancer treatment or the surgical removal of gonads. Use code Z31.84, Encounter for fertility preservation procedure, for fertility preservation encounters

question

Procreative management

answer

Assign code Z31.83 for patients undergoing in vitro fertilization. Assign an additional code to identify the type of infertility. Code Z31.83 is not used for encounters for diagnostic testing prior to starting in vitro fertilization. Assign the reason for the encounter when the patient presents for diagnostic testing. Assign code Z31.41 for encounters for investigations such as sperm counts or fallopian tube insufflation. Assign code Z31.42 for encounters for sperm count following sterilization reversal.

question

Encounters for Testing and Counseling for Genetic Disease

answer

Codes Z31.430, Z31.438, Z31.440, Z31.441, Z31.448, and Z31.5 describe encounters for testing and counseling for genetic disease. If the encounter for genetic screening is not associated with procreative management: Assign a code from subcategory Z13.7, Encounter for screening for genetic and chromosomal anomalies, rather than a code from the Z31.4- series.

question

Encounter for Suspected Maternal or Fetal Condition

answer

Codes from subcategory Z03.7 are used in limited circumstances on a maternal record when an encounter for a suspected maternal or fetal condition is ruled out. Not used when the condition is confirmed; rather, code the confirmed condition. Not used if signs or symptoms are related to the suspected condition or problem present. Codes for the diagnosis/sign or symptom are reported instead. Use codes from subcategory Z03.7, along with other codes, when the encounter is unrelated to the suspected condition being evaluated. Subcategory Z03.7 is not used for encounters for antenatal screening of the mother.
