About coding Pyracin deficiency
The ICD-10-CM code for Pyracin deficiency is E53.1 (Pyridoxine deficiency).
Within E53 (deficiency of other B group vitamins), E53.1 is specifically for Pyridoxine deficiency. Related codes cover Riboflavin deficiency (E53.0), deficiency of other specified B group vitamins (E53.8) and vitamin B deficiency, unspecified (E53.9).
Don't report E53.1 together with the conditions in its Excludes1 note: pyridoxine-responsive sideroblastic anemia (D64.3).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
Don't confuse with (Excludes1 for E53.1)
- pyridoxine-responsive sideroblastic anemia (D64.3)
