2026 ICD-10-CM Diagnosis Code K41.90 – Unilateral femoral hernia, without obstruction or gangrene, not specified as recurrent
What it is
K41.90 identifies a femoral hernia on one side of the groin that is not blocked and has no gangrene. Use it when the record does not specify recurrence.
Clinical signs
Clinical features vary; refer to documentation. Commonly, a femoral hernia appears as a groin or upper-thigh bulge and may be reducible, tender, or more noticeable with standing or straining.
When to use this code
Use K41.90 when the provider documents a unilateral femoral hernia without obstruction or gangrene and does not state that it is recurrent. It also fits cases described as uncomplicated or nonincarcerated, if no obstruction or gangrene is documented. Check documentation for laterality and recurrence details.
Do not use for
Do not use this code if the hernia is obstructed, gangrenous, or documented as recurrent. If the record does not confirm a femoral hernia, check documentation before assigning a code.
Coding tip
Confirm laterality, obstruction status, gangrene, and recurrence before coding; missing details can change the ICD-10 code.
