Other puerperal infections (O86)

ICD-10 code O86 covers a range of infections that occur during the puerperal period, which is the time following childbirth. These codes are used to classify infections specifically related to obstetric surgical wounds, genital tract infections, urinary tract infections, and other specified postpartum infections.

The ICD-10 code O86 and its subcodes precisely identify conditions such as infection of obstetric surgical wounds; including superficial, deep, and organ/space site infections (O86.00 to O86.09); commonly known as postoperative wound infection or infection of surgical incision wounds after cesarean section. Other codes address infections of the genital tract after delivery, such as cervicitis (postpartum inflammation of the cervix, O86.11), endometritis (puerperal endometritis, O86.12), vaginal infections including bacterial vaginosis (O86.13), and other infections like puerperal salpingitis (O86.19). Urinary tract infections post-delivery, including kidney and bladder infections (O86.20 to O86.29), are also classified here. Additionally, codes like O86.4 capture pyrexia of unknown origin following delivery, often linked to postnatal infection or puerperal fever. Specific complications such as puerperal septic thrombophlebitis (O86.81) and postpartum erysipelas (O86.89) are designated to identify these serious infections accurately. These codes help healthcare professionals document and manage postpartum infections effectively, ensuring proper treatment and follow-up care.

Instructional Notations

Use Additional Code

The “use additional code” indicates that a secondary code could be used to further specify the patient’s condition. This note is not mandatory and is only used if enough information is available to assign an additional code.

Type 2 Excludes

A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

  • infection during labor O75.3
  • obstetrical tetanus A34

Clinical Terms

The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.

Erysipelas

An acute infection of the skin caused by species of STREPTOCOCCUS. This disease most frequently affects infants, young children, and the elderly. Characteristics include pink-to-red lesions that spread rapidly and are warm to the touch. The commonest site of involvement is the face.

Streptococcus

A genus of gram-positive, coccoid bacteria whose organisms occur in pairs or chains. No endospores are produced. Many species exist as commensals or parasites on man or animals with some being highly pathogenic. A few species are saprophytes and occur in the natural environment.
