2024 ICD-10-CM Diagnosis Code O33.0

Approximate Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

• Disproportion - major pelvic abnormality
• Disproportion - major pelvic abnormality with antenatal problem
• Pelvis not adequate for delivery
• Problem of pelvis for delivery

Code Edits

The Medicare Code Editor (MCE) detects and reports errors in the coding of claims data. The following ICD-10-CM Code Edits are applicable to this code:

• Maternity diagnoses - The Medicare Code Editor detects inconsistencies in maternity cases by checking a patient's age and any diagnosis on the patient's record. The maternity code edits apply to patients age ange is 9–64 years inclusive (e.g., diabetes in pregnancy, antepartum pulmonary complication).
• Diagnoses for females only - The Medicare Code Editor detects inconsistencies between a patient’s sex and any diagnosis on the patient’s record, these edits apply to FEMALES only .

O33.0 is grouped with Diagnostic Related Groups - MS-DRG Mapping

Diagnostic Related Groups (DRGs) are a classification system used to group together diagnosis codes for the purpose of reimbursement and healthcare management. DRGs are used to standardize the way hospitals and other providers are paid for inpatient services. In this system patients are grouped together based on their principal diagnosis in areas referred to as Major Diagnostic Categories (MDC). Once a patient is assigned a particular diagnostic category, providers receive a predetermined payment rate for the services rendered. This reimbursement rate is often fixed and is meant to cover the cost of care for that patient. Reimbursement is also affected by the relative weight of a diagnostic related group based on the severity of a patient's illness and the associated cost of care during hospitalization.

Diagnostic related groups encourage healthcare providers to focus on quality and efficiency in patient care while managing costs effectively. The diagnosis code is present in the following groups for version MS-DRG V41.0 applicable from 10/01/2023 through 09/30/2024.

The relative weight of a diagnostic related group determines the reimbursement rate based on the severity of a patient's illness and the associated cost of care during hospitalization.

Convert O33.0 to ICD-9-CM

• ICD-9-CM Code: 648.71 - Bone disorder-delivered
  Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.
• ICD-9-CM Code: 648.72 - Bone disorder-del w p/p
  Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.
• ICD-9-CM Code: 653.01 - Pelvic deform NOS-deliv
  Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.

Childbirth Problems

Childbirth is the process of giving birth to a baby. It includes labor and delivery. Usually everything goes well, but problems can happen. They may cause a risk to the mother, baby, or both. Some of the more common childbirth problems include:

• Preterm (premature) labor, when your labor starts before 37 completed weeks of pregnancy
• Premature rupture of membranes (PROM), when your water breaks too early. If labor does not start soon afterwards, this can raise the risk of infection.
• Problems with the placenta, such as the placenta covering the cervix, separating from the uterus before birth, or being attached too firmly to the uterus
• Labor that does not progress, meaning that labor is stalled. This can happen when
  • Your contractions weaken
  • Your cervix does not dilate (open) enough or is taking too long to dilate
  • The baby is not in the right position
  • The baby is too big or your pelvis is too small for the baby to move through the birth canal
• Abnormal heart rate of the baby. Often, an abnormal heart rate is not a problem. But if the heart rate gets very fast or very slow, it can be a sign that your baby is not getting enough oxygen or that there are other problems.
• Problems with the umbilical cord, such as the cord getting caught on the baby's arm, leg, or neck. It's also a problem if cord comes out before the baby does.
• Problems with the position of the baby, such as breech, in which the baby is going to come out feet first
• Shoulder dystocia, when the baby's head comes out, but the shoulder gets stuck
• Perinatal asphyxia, which happens when the baby does not get enough oxygen in the uterus, during labor or delivery, or just after birth
• Perineal tears, tearing of your vagina and the surrounding tissues
• Excessive bleeding, which can happen when the delivery causes tears to the uterus or if you are not able to deliver the placenta after you give birth to the baby
• Post-term pregnancy, when your pregnancy lasts more than 42 weeks

If you have problems in childbirth, your health care provider may need to give you medicines to induce or speed up labor, use tools to help guide the baby out of the birth canal, or deliver the baby by Cesarean section.
