ICD-10 Code M00.132 – Pneumococcal arthritis, left wrist (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M00.132 – Pneumococcal arthritis, left wrist
What it is
M00.132 identifies pneumococcal arthritis affecting the left wrist. Use it when documentation shows a Streptococcus pneumoniae infection causing joint inflammation in that specific wrist.
Clinical signs
Typical findings include a painful, swollen, warm wrist with reduced motion. Clinical features vary; refer to documentation for confirmed septic arthritis and pneumococcal involvement.
When to use this code
Use this code when the provider documents pneumococcal septic arthritis of the left wrist, or clearly identifies Streptococcus pneumoniae as the cause. It is appropriate for confirmed infection of that joint, including inpatient or outpatient encounters. Check documentation if the organism or side is unclear.
Do not use for
Do not use this code for nonspecific arthritis, trauma, or arthritis in another joint. If the record does not confirm pneumococcal infection, check documentation before assigning M00.132.
Coding tip
Capture both the organism and laterality; missing either detail can lead to an incorrect code.
