Coding for Methotrexate for Treating Ectopic Pregnancies- Published on Fri, May 01, 1998
"Ectopic pregnancy has been increasing in recent years, and recent statistics show it now occurs in one out of 60 pregnancies. This increase is thought to be related to an increasing incidence of chlamydia, gonorrhea and other pelvic infections. For those patients who require intervention, the laparoscopic treatment of ectopic pregnancy with salpingectomy (59151) is still the most common, albeit expensive, treatment. But recently, more ob/gyns are considering using the anticancer drug methotrexate as a viable, nonsurgical alternative to salpingectomy.
Methotrexate kills growing cells of the placenta and induces abortion of the ectopic pregnancy. Several new studies -- including a 1997 report in Lancet -- reaffirm that methotrexate may be an effective alternative to surgery. Commenting on the study for Reuters, James Liu, MD, professor of obstetrics and gynecology and head of reproductive endocrinology at the University of Cincinnati, said, Basically, what this study says is you can use either (methotrexate or surgery). From a cost-effective point of view -- and this is something they (the study) didnt address -- if they are both equally effective, and laparoscopy costs you $10,000, lets say, and methotrexate costs you $1,000 for monitoring and ultrasound, which one would you use? They both end up with the same tubal patency rate, they both end up with similar re-operation rates for persistent hCG levels in some of the folks that fail.
Long Follow Up with Methotrexate
While methotrexate is less expensive, a long follow up period is required, and that is precisely what prompted Michael Anthony, MD, FACOG, of Cary Obstetrics and Gynecology, PA to ask what codes should be used for treating ectopic pregnancy with methotrexate. Because of the more intensive follow-up and risk, I feel I should have a special code for this extensive treatment. Use of methotrexate involves a series of office visits to measure hCG levels, possible ultrasounds and numerous phone calls.
Coding for Methotrexate
First of all, its important to note that currently there are no global codes in the CPT
for the medical treatment of ectopic pregnancy with methotrexate. Therefore, the physician can only be reimbursed for itemized services such as administration of the drug, successive hCG level tests and other procedures performed. If the methotrexate is administered by the physician following a D&C, a modifier 58 (Staged Procedure) can be added to the injection procedure code (90782). The drug should be billed using either the CPTs all purpose code for supplies (99070) or the HCPCS J code J9260
(methotrexate sodium, 50mg -- which is a common dosage).
In both cases, correct diagnosis codes need to be attached to both the D&C code and the injection code. The D&C [...]
