Commonly referred to as flatfoot or flat feet when present in both feet.
Summary
Congenital pes planus is a condition where a child is born with an abnormally low or absent arch in the foot, specifically affecting the right foot. It often leads to the entire foot making contact with the ground.
Causes
It is a congenital condition, meaning it is present at birth. The exact cause is often unclear but may involve genetic factors that affect foot development.
Risk Factors
Family history of flatfoot.
Genetic conditions that affect muscle tone or skeletal development.
Symptoms
Difficulty standing on tiptoe.
Feet turning outward.
Pain in the foot, ankle, or lower leg, especially when active.
Shoes wearing out on one side more quickly.
Diagnosis
Physical examination by a healthcare provider.
Imaging tests like X-rays to assess the structure of the foot.
Observation of foot posture and gait while walking.
Treatment Options
Often, no treatment is necessary for asymptomatic cases.
Orthotic devices to provide arch support.
Physical therapy to strengthen foot and ankle muscles.
Surgery in severe cases where flatfoot causes significant pain or functional limitations.
Prognosis and Follow-Up
Many children with congenital pes planus experience little to no symptoms and lead normal lives.
Regular monitoring by a pediatrician or orthopedic specialist to ensure no progression of symptoms or development of complications.
Complications
If symptomatic and untreated, it may lead to foot pain, poor posture, or problems with walking.
Lifestyle & Prevention
Encouraging children to engage in activities that strengthen foot and leg muscles.
Wearing supportive footwear.
When to Seek Professional Help
Persistent pain in the foot or leg.
Changes in walking pattern or frequent tripping.
Difficulty participating in physical activities due to foot discomfort.

Tips for Medical Coders
Ensure the laterality of the condition is correctly noted as "right foot" to differentiate from conditions affecting the left foot or both feet.
Avoid confusing congenital pes planus (Q66.51) with acquired flatfoot deformities, which have different ICD codes.
