Pregnancy is a unique phase of a woman’s life as there are considerable physiological changes that can adversely affect the oral health of women. Maintaining oral health is vital to ensure overall well-being and health. Dental services may be reimbursed and dentists can partner with a reliable dental billing company to accurately code their diagnoses and treatments provided.

Dentists provide preventive, diagnostic and restorative dental treatment for the following commonoral health problems:

  • Gingivitis- Fluctuations in hormones can induce the response to bacteria in the gum tissue.
  • Dental caries- Changes in diet and increased craving for sugary foods can cause tooth pain and infection. Nausea and vomiting increases acidity in the mouth.
  • Pyogenic granuloma-Inflammatory hyperplasia around anterior teeth due to hormonal changes.
  • Erosion of teeth- It stems from vomiting associated with morning sickness.
  • Periodontitis-Pregnant women have increased risk of peridiontitis due to hormonal changes.

Dentists providing specialized care to pregnant women presenting with various dental problems find the coding of dental problems hectic and time-consuming. A medical billing and coding company can assist dentists with accurate dental coding and ensure speedy claims processing while minimizing denials. With a good outsourcing dental billing partner, dentists can focus on treating their patients and ensuring optimum care and patient satisfaction.
