Sarcoid pyelonephritis

This code signifies kidney inflammation (pyelonephritis) specifically caused by sarcoidosis, a systemic inflammatory disease characterized by granuloma formation. It indicates renal involvement as a manifestation of sarcoidosis.

Apply this code when documentation clearly states pyelonephritis is a direct consequence of sarcoidosis. This typically occurs in patients with a confirmed diagnosis of sarcoidosis who subsequently develop kidney infection attributed to the underlying systemic condition.

• Always sequence the underlying sarcoidosis code (D86.x) first, followed by this code to show the manifestation.
• Ensure documentation explicitly links the pyelonephritis to sarcoidosis; avoid using for general pyelonephritis in a patient with sarcoidosis if no causal link is stated.
• Do not confuse with other causes of pyelonephritis (e.g., bacterial) even if sarcoidosis is present.
