Treatment plans are a must, experts say. You've treated your chiropractic patient, you've selected the correct codes, and you've submitted your claim. All set, right? Not quite. Check out this common mistake that chiropractors make. "Many chiropractors do not create written chiropractic treatment plans for every new patient," says Marty Kotlar, DC, CHCC, CBCS, president of Target Coding, a chiropractic coding and billing consulting firm. "Medicare would like to see chiropractors include the following information with every new patient plan of care," Kotlar says: 1. The history 2. Present illness 3. Family history 4. The past health history 5. The physical examination 6. The diagnosis 7. The plan -- This should include: 8. Signature/initials to authenticate the records.
