Clinical Information

• Bicornuate Uterus

  a congenital uterine anomaly in which the uterus is divided into two uterine horns with a significant cleft at the uterine fundus due to partial fusion of the mullerian ducts. bicornuate uterus is sometimes associated with a longitudinal vaginal septum and abnormal development of renal tracts.

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 .

O34.599 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 O34.599 to ICD-9-CM

• ICD-9-CM Code: 654.40 - Abn grav uterus NEC-unsp
  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.

Patient Education

Uterine Diseases

The uterus, or womb, is the place where a baby grows when a woman is pregnant. The first sign of a problem with the uterus may be bleeding between periods or after sex. Causes can include hormones, thyroid problems, fibroids, polyps, cancer, infection, or pregnancy.

Treatment depends on the cause. Sometimes birth control pills treat hormonal imbalances. If a thyroid problem is the cause, treating it may also stop the bleeding. If you have cancer or hyperplasia, an overgrowth of normal cells in the uterus, you may need surgery.

With two other uterine problems, tissue that normally lines the uterus grows where it is not supposed to. In endometriosis, it grows outside the uterus. In adenomyosis, it grows in the uterus's outside walls. Pain medicine may help. Other treatments include hormones and surgery.
