2026 ICD-10-CM Diagnosis Code B96.89Other specified bacterial agents as the cause of diseases classified elsewhere
ICD-10-CM B96.89
B96.89 is a billable ICD-10-CM diagnosis code for other specified bacterial agents as the cause of diseases classified elsewhere. It is valid on HIPAA claims for fiscal year 2026 (October 1, 2025 through September 30, 2026) and groups to MS-DRG 867 through 869. The code is not accepted as a principal diagnosis by the Medicare Code Editor. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Bacterial infections.

Medicare Code Editor checks that affect claim validity for B96.89.
There are selected codes that describe a circumstance which influences an individual's health status but not a current illness or injury, or codes that are not specific manifestations but may be due to an underlying cause. These codes are considered unacceptable as a principal diagnosis.

Clinical InformationClinical
Chorioamnionitis
inflammation of the placental membranes (chorion; amnion) and connected tissues such as fetal blood vessels and umbilical cord. it is often associated with intrauterine ascending infections during pregnancy.Enthesitis
inflammation at the site of insertion of ligaments, tendons, and other fibrous structures into bone.Enthesitis-Related Arthritis|ERA|ERA|Enthesitis-Related JIA|Enthesitis-Related JIA|Enthesitis-Related Juvenile Idiopathic Arthritis|Enthesitis-Related Juvenile Idiopathic Arthritis
a category of juvenile idiopathic arthritis associated with arthritis and enthesitis, which may involve the axial skeleton. it is a form of juvenile spondyloarthritis.Bacterial Endophthalmitis
endophthalmitis caused by bacterial infection of the vitreous or aqueous humors.Chronic Prostatitis
an infectious or non-infectious chronic inflammatory process that affects the prostate gland.Neonatal Dacryocystitis
inflammation of the lacrimal sac in a newborn due to blocked drainage of tears or infection.Omphalitis
inflammation of the umbilical cord stump in newborns.Acute Bacterial Prostatitis|acute bacterial prostatitis
an acute infection of the prostate gland caused by bacteria, most often escherichia coli, proteus mirabilis, klebsiella, and pseudomonas aeruginosa. signs and symptoms include fever, lower back pain, urinary frequency, and painful urination. the urinalysis reveals the presence of white cells. risk factors include intraprostatic ductal reflux, phimosis, urinary tract infections, and unprotected anal intercourse.Bacterial Prostatitis
an acute or chronic bacterial infection that affects the prostate gland.Chronic Bacterial Prostatitis|chronic bacterial prostatitis
a chronic infection of the prostate gland caused by bacteria. it is manifested with recurring urinary tract infections. the culture of the prostatic fluid, semen, or post-massage urine specimen reveals the presence of bacteria.Acute Prostatitis
an acute inflammatory process that affects the prostate gland. it is caused by bacteria, most often escherichia coli, proteus mirabilis, klebsiella, and pseudomonas aeruginosa.Chorioamnionitis
a morphologic finding indicating inflammation of the fetal sac membranes. it is characterized by neutrophilic infiltration of the amnion and chorion.Clinical Chorioamnionitis
inflammation of the fetal sac membranes, characterized by otherwise unexplained fever (at or above 38 degree c (100.4f)) with one or more of the following: uterine tenderness and/or irritability, leukocytosis, fetal tachycardia, maternal tachycardia, or malodorous vaginal discharge.Histologic Chorioamnionitis|Acute Amnionitis|Acute Chorioamnionitis|Acute Choriodeciduitis|Acute Chorionitis|Microscopic Chorioamnionitis
inflammation of the fetal sac membranes that is characterized by neutrophilic infiltration of the amnion and chorion.Acute and Subacute Endocarditis, Unspecified|Acute and subacute endocarditis, unspecified
evidence of acute and subacute endocarditis.Acute Endocarditis
acute inflammation of the endocardium. bacteria is the usual etiologic agent, and the distinction between "acute" and "subacute" has traditionally been made based on the pathogenic organism and clinical presentation.

Bacterial Infections
Bacteria are tiny organisms (living things) that have only one cell. Under a microscope, they look like balls, rods, or spirals. They can be found almost everywhere on Earth. There are lots of bacteria in and on your body. In fact, your body has about 10 times more bacteria cells than human cells.

Questions About B96.89Overview
Is B96.89 a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report other specified bacterial agents as the cause of diseases classified elsewhere on HIPAA-covered claims from October 1, 2025 through September 30, 2026.
What MS-DRG does B96.89 group to?
On inpatient claims, other specified bacterial agents as the cause of diseases classified elsewhere maps to MS-DRG 867, 868, 869, with relative weights from 0.7297 to 2.0932 depending on complications. Higher weights mean higher Medicare reimbursement.
Can B96.89 be a principal diagnosis?
No. The Medicare Code Editor rejects this code as a principal diagnosis because other specified bacterial agents as the cause of diseases classified elsewhere describes a circumstance that influences health status rather than a current illness. Report it as a secondary diagnosis.
What is the ICD-9 equivalent of B96.89?
Under the General Equivalence Mappings, other specified bacterial agents as the cause of diseases classified elsewhere converts to ICD-9-CM 041.89 (oth specf bacteria). The mapping is approximate, so confirm the match fits the documentation.
Footnotes
[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
