K59.0 Constipation

Name of the Condition

• Constipation
• Medical term: Constipation (ICD-10-CM Code: K59.0)

Summary

Constipation is a common gastrointestinal condition characterized by infrequent bowel movements, difficulty passing stools, or a feeling of incomplete evacuation. It often involves hard, dry stools and may be accompanied by straining or discomfort.

Causes

Constipation can result from various factors, including low fiber intake, inadequate fluid consumption, sedentary behavior, or certain medications (e.g., opioids, antacids). It may also be linked to hormonal changes, neurological conditions, or disruptions in routine.

Risk Factors

• Older age
• Female gender
• Low-fiber diet
• Physical inactivity
• Dehydration
• Use of constipating medications

Symptoms

• Fewer than three bowel movements per week
• Straining during defecation
• Hard or lumpy stools
• Sensation of incomplete evacuation
• Abdominal bloating or discomfort

Diagnosis

Diagnosis typically involves a medical history, physical examination, and review of dietary habits. Additional tests (e.g., colonoscopy, anorectal manometry) may be performed to rule out structural or functional issues if symptoms are persistent or severe.

Treatment Options

• Dietary adjustments: Increased fiber and fluid intake to soften stools.
• Lifestyle changes: Regular exercise to stimulate bowel function.
• Medications: Laxatives, stool softeners, or prokinetic agents for symptom relief.
• Biofeedback therapy: For functional issues like pelvic floor dysfunction.

Prognosis and Follow-Up

Most cases resolve with lifestyle modifications or short-term treatment. Chronic constipation may require ongoing management. Follow-up is recommended if symptoms persist or worsen.

Complications

• Hemorrhoids
• Anal fissures
• Fecal impaction
• Bowel obstruction (rare)

Lifestyle & Prevention

• Maintain a high-fiber diet (fruits, vegetables, whole grains).
• Stay hydrated with adequate water intake.
• Engage in regular physical activity.
• Establish consistent bowel habits (e.g., responding to urges promptly).

When to Seek Professional Help

Consult a healthcare provider if constipation is severe, lasts longer than three weeks, or is accompanied by rectal bleeding, unexplained weight loss, or persistent abdominal pain.

Tips for Medical Coders

Document the clinical details supporting the diagnosis, including symptom frequency, duration, and any contributing factors. Ensure the code aligns with the patient’s documented condition and avoid using this code for acute or secondary causes of constipation unless specified.
