Ob-Gyn Coding Alert

Hint: You can report complications before or after delivery.

If your ob-gyn provides additional visits outside of the normal global ob package, you can see increased payment. However, you’ll have to make sure you’ve coded high-risk or complicated obstetrical care correctly — and that means perfecting your diagnosis coding skills.

Insist on Perfect ICD-9s

You have to link the ICD-9 code on the CMS-1500 claim form (boxes 21 and 24E) to an E/M code, for example, to demonstrate the reason for the additional service. You can add this to the claim that includes the global service, or you can submit it as an additional claim.

Example: A 33-year-old patient, gravida 3, para 2 (both normal spontaneous vaginal delivery [NSVD] full term), is seen in the office 19 times due to developing pre-eclampsia. After the delivery, you review the case and find that the patient required six additional visits (beyond the usual 13) for this care. The documentation for three of these visits supports reporting 99212 (Office or other outpatient visit for the evaluation and management of an established patient ... Physicians typically spend 10 minutes face-to-face with the patient and/or family), while three of the visits have more extensive documentation that supports reporting 99213 (Office or other outpatient visit for the evaluation and management of an established patient ... Physicians typically spend 15 minutes face-to-face with the patient and/or family).

In addition, after delivery, the patient experiences prolonged pain and irritation due to a hemorrhoid. The ob-gyn sees her for a thrombosed hemorrhoid, which he incises in the office two weeks post-delivery. Finally, the ob-gyn rechecks the patient at her six weeks postpartum visit.

Break it down: When coding for this patient, remember the claim form must note both the CPT^® codes describing the additional services, as well as the diagnoses that depict why the patient required the additional services.

Heads up: Notice the fifth digits of these ICD-9 codes. 643.4x (Mild or unspecified pre-eclampsia) will end in a “3” if the care was given before the patient delivered in the outpatient setting.  This digit changes to “1” if the patient is admitted to the hospital with this complication and then goes on to deliver.  Once the patient leaves the hospital after delivery, any complication code reported will carry a “4” as the fifth digit. Therefore, the hemorrhoids she developed following delivery will be reported as 671.84 (Other venous complications).  .

ICD-10: When your diagnosis code system changes in 2013, you should look to the following equivalents:

• 642.41 & 642.43 will become:

       o  O14.00 Mild pre-eclampsia, unspecified trimester

       o  O14.02, Mild pre-eclampsia, second trimester

       o  O14.03, Mild pre-eclampsia, third trimester

• O14.90, Unspecified pre-eclampsia, unspecified trimester

       o  O14.92, Unspecified pre-eclampsia, second trimester

       o  O14.93, Unspecified pre-eclampsia, third trimester

• 671.84 will become O87.2 (Hemorrhoids in the puerperium).

When to Submit Your Claim

You have two options as to when to submit your claim — after the patient delivers, when you can count the number of visits beyond the global ob package, or during her pregnancy when the complication occurs.

Option 1: Most coders recommend the former option. The extent to which complications create more work for the ob-gyn isn’t calculable until after the delivery, so you may wait until that point to decide what extra services to code. Best bet: To ensure you’re not losing revenue in this regard, you should have a system for carefully reviewing patient records to make sure you coded any charges beyond the global.

Option 2: If timely filing is an issue with your payer you may want to report additional visits and services during the pregnancy, but be prepared for a denial if you are still in the antepartum period.  While your diagnosis code will accurately reflect the complication being managed, many payers will deny the visit because the patient has not yet delivered.  If this happens, you can appeal these denials after delivery and not be subject to any payer timely filing rules.  If If you’re paid additional reimbursement for these services, but the patient delivers early so that the total number of antepartum visits did not exceed the global package, you may have to return some of the overpayment.

Red flag: Some payers have specific guidelines for visits or other services paid outside the global package, so you should check with them so see which option you should use.

Keep in mind: The term “high-risk” may represent a current complication, or it may involve a concern that the pregnancy may not go well due to previous history. Payers generally recognize complications, but they do not allow extra for the ob-gyn merely worrying about the pregnancy.
