Reporting and Coding Different Types of Hernia

Hernia is a common problem which causes a localized bulge in the abdomen or groin. The condition occurs when there is a weakness or hole in the peritoneum – the muscular wall that usually keeps abdominal organs in place. This weakness in the peritoneum allows organs and tissues to push through, or herniate, producing a bulge. Generally, a hernia develops between your chest and hips. The condition causes very few symptoms or sometimes no symptoms at all, although in some cases you may notice a swelling or lump in your tummy (abdomen) or groin. The lump may disappear when you lie down, and sometimes it can be pushed back. Coughing or straining may make it reappear. Most hernias aren’t immediately life threatening, but they don’t improve on their own and can lead to severe, life-threatening complications. Medications and self-care measures can help reduce the immediate symptoms to some extent. Physicians, in most cases will recommend surgery to fix a hernia that’s painful or enlarging. As reimbursement rules, regulations, and payer policies are subjected to changes frequently, partnering with an experienced medical billing and coding company is the best option to ensure clean and accurate claims for hernia surgery.

One of the common symptoms associated with the condition is a bulge or painless lump in the affected area. However, the condition may be the cause of serious discomfort and pain, with symptoms often becoming worse when standing, straining or lifting heavy items. Other associated symptoms include sudden, severe pain or discomfort in the affected area (especially when bending over, coughing, or lifting), nausea, vomiting, constipation, a feeling of pressure/heaviness in the abdomen, aburning, gurgling, or aching sensation at the site of the bulge, chest pain, acid reflex and difficulty swallowing.

Types of Hernia

• Inguinal hernia – This is one of the most common types of hernia which mainly affects men. It occurs when the intestines push through a weak spot or tear in the lower abdominal wall, often in the inguinal canal.
• Hiatal hernia – This condition is most common in people over 50 years old. It occurs when part of your stomach protrudes up through the diaphragm into your chest cavity.
• Umbilical hernia – This condition occurs when the intestines bulge through their abdominal wall near the belly button. It is more common among babies below 6 months. This is the only type of hernia that often goes away on its own as the abdominal wall muscles get stronger, typically by the time the child becomes 1 year old.
• Femoral hernia –This type occurs when fatty tissue or a part of your bowel pokes through into your groin at the top of your inner thigh.
• Incisional/ventral hernia – The condition arises when tissue pokes through a surgical wound in your abdomen that hasn’t fully healed.
• Epigastric hernia – It occurs when fatty tissue pokes through your abdomen, between your navel and the lower part of your breastbone (sternum).
• Diaphragmatic hernia – This type of hernia occurs when organs in your abdomen move into your chest through an opening in the diaphragm. This condition can also affect babies if their diaphragm doesn’t develop properly in the womb.

There is no specific cause or reason for a hernia to occur (except the case of incisional hernia that occurs due to a complication of abdominal surgery). They are generally caused by a combination of muscle weakness and strain. The condition occurs more commonly in men than in women and the risks increases with age. Other factors that increase your risk of developing a hernia include family history of the condition, obesity, chronic cough, constipation and conditions like cystic fibrosis, enlarged prostate, peritoneal dialysis, abdominal fluid and undescended testicles.

Diagnosis and Treatment Methods

Hernias are usually diagnosed through a detailed physical examination wherein your physician may feel for a bulge in the abdomen or groin that gets larger when you stand, cough or strain. Diagnostic imaging tests like X-ray, Ultrasound and Endoscopy may be conducted to correctly diagnose the symptoms and determine the exact type of hernia.

Treatment options for this condition depend on the size and type of hernia and the severity of your symptoms. Enlarging or painful hernias usually require surgery to relieve discomfort and prevent serious complications. There are two main types of surgical intervention for hernia –open surgery and laparoscopic operation (keyhole surgery). In the case of open surgery, the surgeon makes an incision and pushes the protruding tissue back into your abdomen. On the other hand, laparoscopic is a less invasive technique where several small incisions are made in your abdomen, thereby allowing the surgeon to use various special instruments to repair the hernia.

General surgery medical coding involves using the specific ICD-10 diagnosis codes, CPT procedure codes, HCPCS codes and MS-DRG codes for reporting hernia on your medical claims.

Integrating positive lifestyle habits can help treat the symptoms of hernia in the long run. These include – making dietary changes, avoiding large or heavy meals, stopping the habit of smoking and doing certain kind of exercises (that help strengthen the muscles around the hernia site) and maintaining a healthy body weight.

Medical billing and coding requires knowledge regarding the right coding modifiers and payer-specific medical billing are essential for correct and on-time reimbursement. With all the complexities involved, the support of a reliable and experienced medical coding service provider can be useful for reporting hernia surgical repair procedure correctly.
